[p. 573] Justice Scalia delivered the opinion of the Court.
We consider whether a District of Columbia prohibition on the possession of usable handguns in the home violates the Second Amendment to the Constitution. [p. 574]

#### I

The District of Columbia generally prohibits the possession of handguns. It is a crime to carry an unregistered [p. 575] firearm, and the registration of handguns is prohibited. See D. C. Code §§7–2501.01(12), 7–2502.01(a), 7– 2502.02(a)(4) (2001). Wholly apart from that prohibition, no person may carry a handgun without a license, but the chief of police may issue licenses for 1-year periods. See §§22–4504(a), 22–4506. District of Columbia law also requires residents to keep their lawfully owned firearms, such as registered long guns, "unloaded and disassembled or bound by a trigger lock or similar device" unless they are located in a place of business or are being used for lawful recreational activities. See §7–2507.02.
Respondent Dick Heller is a D. C. special police officer authorized to carry a handgun while on duty at the Federal Judicial Center. He applied for a registration certificate for a handgun that he wished to keep at home, but the District refused. He thereafter filed a lawsuit in the Federal District Court for the District of Columbia seeking, [p. 576] on Second Amendment grounds, to enjoin the city from enforcing the bar on the registration of handguns, the licensing requirement insofar as it prohibits the carrying of a firearm in the home without a license, and the trigger-lock requirement insofar as it prohibits the use of "functional firearms within the home." App. 59a. The District Court dismissed respondent's complaint, see Parker v. District of Columbia, 311 F.Supp.2d 103, 109 (2004). The Court of Appeals for the District of Columbia Circuit, construing his complaint as seeking the right to render a firearm operable and carry it about his home in that condition only when necessary for self-defense, reversed, see Parker v. District of Columbia, 478 F.3d 370, 401 (2007). It held that the Second Amendment protects an individual right to possess firearms and that the city's total ban on handguns, as well as its requirement that firearms in the home be kept nonfunctional even when necessary for self-defense, violated that right. See id., at 395, 399–401. The Court of Appeals directed the District Court to enter summary judgment for respondent. We granted certiorari. 552 U.S. 1035 (2007).

#### II

We turn first to the meaning of the Second Amendment.

##### A

The Second Amendment provides: "A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed." In interpreting this text, we are guided by the principle that "[t]he Constitution was written to be understood by the voters; its words and phrases were used in their normal and ordinary as distinguished from technical meaning." United States v. Sprague, 282 U.S. 716, 731 (1931); see also Gibbons v. Ogden, 9 Wheat. 1, 188 (1824). Normal meaning may of [p. 577] course include an idiomatic meaning, but it excludes secret or technical meanings that would not have been known to ordinary citizens in the founding generation.
The two sides in this case have set out very different interpretations of the Amendment. Petitioners and today's dissenting Justices believe that it protects only the right to possess and carry a firearm in connection with militia service. See Brief for Petitioners 11–12; post, at 636-637 (Stevens, J., dissenting). Respondent argues that it protects an individual right to possess a firearm unconnected with service in a militia, and to use that arm for traditionally lawful purposes, such as self-defense within the home. See Brief for Respondent 2–4.
The Second Amendment is naturally divided into two parts: its prefatory clause and its operative clause. The former does not limit the latter grammatically, but rather announces a purpose. The Amendment could be rephrased, "Because a well regulated Militia is necessary to the security of a free State, the right of the people to keep and bear Arms shall not be infringed." See J. Tiffany, A Treatise on Government and Constitutional Law §585, p. 394 (1867); Brief for Professors of Linguistics and English as Amici Curiae 3 (hereinafter Linguists' Brief). Although this structure of the Second Amendment is unique in our Constitution, other legal documents of the founding era, particularly individual-rights provisions of state constitutions, commonly included a prefatory statement of purpose. See generally Volokh, The Commonplace Second Amendment, 73 N. Y. U. L. Rev. 793, 814–821 (1998).
Logic demands that there be a link between the stated purpose and the command. The Second Amendment would be nonsensical if it read, "A well regulated Militia, being necessary to the security of a free State, the right of the people to petition for redress of grievances shall not be infringed." That requirement of logical connection may cause a prefatory clause to resolve an ambiguity in the operative clause [p. 578] ("The separation of church and state being an important objective, the teachings of canons shall have no place in our jurisprudence." The preface makes clear that the operative clause refers not to canons of interpretation but to clergymen.) But apart from that clarifying function, a prefatory clause does not limit or expand the scope of the operative clause. See F. Dwarris, A General Treatise on Statutes 268–269 (P. Potter ed. 1871) (hereinafter Dwarris); T. Sedgwick, The Interpretation and Construction of Statutory and Constitutional Law 42–45 (2d ed. 1874). "'It is nothing unusual in acts...for the enacting part to go beyond the preamble; the remedy often extends beyond the particular act or mischief which first suggested the necessity of the law.'" J. Bishop, Commentaries on Written Laws and Their Interpretation §51, p. 49 (1882) (quoting Rex v. Marks, 3 East, 157, 165 (K. B. 1802)). Therefore, while we will begin our textual analysis with the operative clause, we will return to the prefatory clause to ensure that our reading of the operative clause is consistent with the announced purpose. [p. 579]
1. Operative Clause.
a. "Right of the People." The first salient feature of the operative clause is that it codifies a "right of the people." The unamended Constitution and the Bill of Rights use the phrase "right of the people" two other times, in the First Amendment's Assembly-and-Petition Clause and in the Fourth Amendment's Search-and-Seizure Clause. The Ninth Amendment uses very similar terminology ("The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people"). All three of these instances unambiguously refer to individual rights, not "collective" rights, or rights that may be exercised only through participation in some corporate body.
Three provisions of the Constitution refer to "the people" in a context other than "rights"—the famous preamble ("We the people"), §2 of Article I (providing that "the people" will choose members of the House), and the Tenth Amendment (providing that those powers not given the Federal Government remain with "the States" or "the people"). Those provisions arguably refer to "the people" acting collectively— [p. 580] but they deal with the exercise or reservation of powers, not rights. Nowhere else in the Constitution does a "right" attributed to "the people" refer to anything other than an individual right.
What is more, in all six other provisions of the Constitution that mention "the people," the term unambiguously refers to all members of the political community, not an unspecified subset. As we said in United States v. Verdugo-Urquidez, 494 U.S. 259, 265 (1990):
   "'[T]he people' seems to have been a term of art employed in select parts of the Constitution.... [Its uses] sugges[t] that 'the people' protected by the Fourth Amendment, and by the First and Second Amendments, and to whom rights and powers are reserved in the Ninth and Tenth Amendments, refers to a class of persons who are part of a national community or who have otherwise developed sufficient connection with this country to be considered part of that community."
This contrasts markedly with the phrase "the militia" in the prefatory clause. As we will describe below, the "militia" in colonial America consisted of a subset of "the people"— those who were male, able bodied, and within a certain age range. Reading the Second Amendment as protecting only the right [p. 581] to "keep and bear Arms" in an organized militia therefore fits poorly with the operative clause's description of the holder of that right as "the people."
We start therefore with a strong presumption that the Second Amendment right is exercised individually and belongs to all Americans.
b. "Keep and bear Arms." We move now from the holder of the right—"the people"—to the substance of the right: "to keep and bear Arms."
Before addressing the verbs "keep" and "bear," we interpret their object: "Arms." The 18th-century meaning is no different from the meaning today. The 1773 edition of Samuel Johnson's dictionary defined "arms" as "weapons of offence, or armour of defence." 1 Dictionary of the English Language 107 (4th ed.) (hereinafter Johnson). Timothy Cunningham's important 1771 legal dictionary defined "arms" as "any thing that a man wears for his defence, or takes into his hands, or useth in wrath to cast at or strike another." 1 A New and Complete Law Dictionary (1771); see also N. Webster, American Dictionary of the English Language (1828) (reprinted 1989) (hereinafter Webster) (similar).
The term was applied, then as now, to weapons that were not specifically designed for military use and were not employed in a military capacity. For instance, Cunningham's legal dictionary gave as an example of usage: "Servants and labourers shall use bows and arrows on Sundays, &c. and not bear other arms." See also, e.g., An Act for the trial of Negroes, 1797 Del. Laws ch. XLIII, §6, p. 104, in 1 First Laws of the State of Delaware 102, 104 (J. Cushing ed. 1981 (pt. 1)); see generally State v. Duke, 42 Tex. 455, 458 (1874) (citing decisions of state courts construing "arms"). Although one founding-era thesaurus limited "arms" (as opposed to "weapons") to "instruments of offence generally made use of in war," even that source stated that all firearms constituted "arms." 1 J. Trusler, The Distinction Between Words Es- [p. 582] teemed Synonymous in the English Language 37 (1794) (emphasis added).
Some have made the argument, bordering on the frivolous, that only those arms in existence in the 18th century are protected by the Second Amendment. We do not interpret constitutional rights that way. Just as the First Amendment protects modern forms of communications, e.g., Reno v. American Civil Liberties Union, 521 U.S. 844, 849 (1997), and the Fourth Amendment applies to modern forms of search, e.g., Kyllo v. United States, 533 U.S. 27, 35–36 (2001), the Second Amendment extends, prima facie, to all instruments that constitute bearable arms, even those that were not in existence at the time of the founding.
We turn to the phrases "keep arms" and "bear arms." Johnson defined "keep" as, most relevantly, "[t]o retain; not to lose," and "[t]o have in custody." Johnson 1095. Webster defined it as "[t]o hold; to retain in one's power or possession." No party has apprised us of an idiomatic meaning of "keep Arms." Thus, the most natural reading of "keep Arms" in the Second Amendment is to "have weapons."
The phrase "keep arms" was not prevalent in the written documents of the founding period that we have found, but there are a few examples, all of which favor viewing the right to "keep Arms" as an individual right unconnected with militia service. William Blackstone, for example, wrote that Catholics convicted of not attending service in the Church of England suffered certain penalties, one of which was that they were not permitted to "keep arms in their houses." 4 Commentaries on the Laws of England 55 (1769) (hereinafter Blackstone); see also 1 W. & M., c. 15, §4, in 3 Eng. Stat. at Large 422 (1689) ("[N]o Papist...shall or may have or keep in his House...any Arms..."); 1 Hawkins, Treatise on the Pleas of the Crown 26 (1771) (similar). Petitioners point to militia laws of the founding period that required militia members to "keep" arms in connection with [p. 583] militia service, and they conclude from this that the phrase "keep Arms" has a militia-related connotation. See Brief for Petitioners 16–17 (citing laws of Delaware, New Jersey, and Virginia). This is rather like saying that, since there are many statutes that authorize aggrieved employees to "file complaints" with federal agencies, the phrase "file complaints" has an employment-related connotation. "Keep arms" was simply a common way of referring to possessing arms, for militiamen and everyone else.
[p. 584] At the time of the founding, as now, to "bear" meant to "carry." See Johnson 161; Webster; T. Sheridan, A Complete Dictionary of the English Language (1796); 2 Oxford English Dictionary 20 (2d ed. 1989) (hereinafter Oxford). When used with "arms," however, the term has a meaning that refers to carrying for a particular purpose—confrontation. In Muscarello v. United States, 524 U.S. 125 (1998), in the course of analyzing the meaning of "carries a firearm" in a federal criminal statute, Justice Ginsburg wrote that "[s]urely a most familiar meaning is, as the Constitution's Second Amendment...indicate[s]: 'wear, bear, or carry...upon the person or in the clothing or in a pocket, for the purpose...of being armed and ready for offensive or defensive action in a case of conflict with another person.'" Id., at 143 (dissenting opinion) (quoting Black's Law Dictionary 214 (6th ed. 1998)). We think that Justice Ginsburg accurately captured the natural meaning of "bear arms." Although the phrase implies that the carrying of the weapon is for the purpose of "offensive or defensive action," it in no way connotes participation in a structured military organization.
From our review of founding-era sources, we conclude that this natural meaning was also the meaning that "bear arms" had in the 18th century. In numerous instances, "bear arms" was unambiguously used to refer to the carrying of weapons outside of an organized militia. The most prominent examples are those most relevant to the Second Amendment: Nine state constitutional provisions written in the 18th century or the first two decades of the 19th, which enshrined a right of citizens to "bear arms in defense of themselves and the state" or "bear arms in defense of himself and [p. 585] the state."It is clear from those formulations that "bear arms" did not refer only to carrying a weapon in an organized military unit. Justice James Wilson interpreted the Pennsylvania Constitution's armsbearing right, for example, as a recognition of the natural right of defense "of one's person or house"—what he called the law of "self preservation." 2 Collected Works of James Wilson 1142, and n. x (K. Hall & M. Hall eds. 2007) (citing Pa. Const., Art. IX, §21 (1790)); see also T. Walker, Introduction to American Law 198 (1837) ("Thus the right of self-defence [is] guaranteed by the [Ohio] constitution"); see also id., at 157 (equating Second Amendment with that provision of the Ohio Constitution). That was also the interpretation of those state constitutional provisions adopted by pre-Civil War state courts. These pro- [p. 586] visions demonstrate—again, in the most analogous linguistic context—that "bear arms" was not limited to the carrying of arms in a militia.
The phrase "bear Arms" also had at the time of the founding an idiomatic meaning that was significantly different from its natural meaning: "to serve as a soldier, do military service, fight" or "to wage war." See Linguists' Brief 18; post, at 646 (Stevens, J., dissenting). But it unequivocally bore that idiomatic meaning only when followed by the preposition "against," which was in turn followed by the target of the hostilities. See 2 Oxford 21. (That is how, for example, our Declaration of Independence ¶28, used the phrase: "He has constrained our fellow Citizens taken Captive on the high Seas to bear Arms against their Country....") Every example given by petitioners' amici for the idiomatic meaning of "bear arms" from the founding period either includes the preposition "against" or is not clearly idiomatic. See Linguists' Brief 18–23. Without the preposition, "bear arms" normally meant (as it continues to mean today) what Justice Ginsburg's opinion in Muscarello said.
In any event, the meaning of "bear arms" that petitioners and Justice Stevens propose is not even the (sometimes) idiomatic meaning. Rather, they manufacture a hybrid definition, whereby "bear arms" connotes the actual carrying of arms (and therefore is not really an idiom) but only in the service of an organized militia. No dictionary has ever adopted that definition, and we have been apprised of no source that indicates that it carried that meaning at the time of the founding. But it is easy to see why petitioners and the dissent are driven to the hybrid definition. Giving "bear Arms" its idiomatic meaning would cause the protected right to consist of the right to be a soldier or to wage war—an absurdity that no commentator has ever endorsed. See L. Levy, Origins of the Bill of Rights 135 (1999). Worse still, [p. 587] the phrase "keep and bear Arms" would be incoherent. The word "Arms" would have two different meanings at once: "weapons" (as the object of "keep") and (as the object of "bear") one-half of an idiom. It would be rather like saying "He filled and kicked the bucket" to mean "He filled the bucket and died." Grotesque.
Petitioners justify their limitation of "bear arms" to the military context by pointing out the unremarkable fact that it was often used in that context—the same mistake they made with respect to "keep arms." It is especially unremarkable that the phrase was often used in a military context in the federal legal sources (such as records of congressional debate) that have been the focus of petitioners' inquiry. Those sources would have had little occasion to use it except in discussions about the standing army and the militia. And the phrases used primarily in those military discussions include not only "bear arms" but also "carry arms," "possess arms," and "have arms"—though no one thinks that those other phrases also had special military meanings. See Barnett, Was the Right to Keep and Bear Arms Conditioned on Service in an Organized Militia?, 83 Tex. L. Rev. 237, 261 (2004). The common references to those "fit to bear arms" in congressional discussions about the militia are matched by use of the same phrase in the few nonmilitary federal contexts where the concept would be relevant. See, e.g., 30 Journals of Continental Congress 349–351 (J. Fitzpatrick ed. 1934). Other legal sources frequently used "bear arms" in nonmilitary contexts. Cunningham's legal dictionary, cited [p. 588] above, gave as an example of its usage a sentence unrelated to military affairs ("Servants and labourers shall use bows and arrows on Sundays, &c. and not bear other arms"). And if one looks beyond legal sources, "bear arms" was frequently used in nonmilitary contexts. See Cramer & Olson, What Did "Bear Arms" Mean in the Second Amendment?, 6 Georgetown J. L. & Pub. Pol'y 511 (2008) (identifying numerous nonmilitary uses of "bear arms" from the founding period).
Justice Stevens points to a study by amici supposedly showing that the phrase "bear arms" was most frequently used in the military context. See post, at 647-648, n. 9; Linguists' Brief 24. Of course, as we have said, the fact that the phrase was commonly used in a particular context does not show that it is limited to that context, and, in any event, we have given many sources where the phrase was used in nonmilitary contexts. Moreover, the study's collection appears to include (who knows how many times) the idiomatic phrase "bear arms against," which is irrelevant. The amici also dismiss examples such as "'bear arms...for the purpose of killing game'" because those uses are "expressly [p. 589] qualified." Linguists' Brief 24. (Justice Stevens uses the same excuse for dismissing the state constitutional provisions analogous to the Second Amendment that identify private-use purposes for which the individual right can be asserted. See post, at 647.) That analysis is faulty. A purposive qualifying phrase that contradicts the word or phrase it modifies is unknown this side of the looking glass (except, apparently, in some courses on Linguistics). If "bear arms" means, as we think, simply the carrying of arms, a modifier can limit the purpose of the carriage ("for the purpose of self defense" or "to make war against the King"). But if "bear arms" means, as the petitioners and the dissent think, the carrying of arms only for military purposes, one simply cannot add "for the purpose of killing game." The right "to carry arms in the militia for the purpose of killing game" is worthy of the mad hatter. Thus, these purposive qualifying phrases positively establish that "to bear arms" is not limited to military use.
Justice Stevens places great weight on James Madison's inclusion of a conscientious-objector clause in his original draft of the Second Amendment: "but no person religiously scrupulous of bearing arms, shall be compelled to render military service in person." Creating the Bill of Rights 12 (H. Veit, K. Bowling, & C. Bickford eds. 1991) (hereinafter Veit). He argues that this clause establishes that the drafters of the Second Amendment intended "bear Arms" to refer only [p. 590] to military service. See post, at 660-661. It is always perilous to derive the meaning of an adopted provision from another provision deleted in the drafting process. In any case, what Justice Stevens would conclude from the deleted provision does not follow. It was not meant to exempt from military service those who objected to going to war but had no scruples about personal gunfights. Quakers opposed the use of arms not just for militia service, but for any violent purpose whatsoever—so much so that Quaker frontiersmen were forbidden to use arms to defend their families, even though "[i]n such circumstances the temptation to seize a hunting rifle or knife in self-defense...must sometimes have been almost overwhelming." P. Brock, Pacifism in the United States 359 (1968); see M. Hirst, The Quakers in Peace and War 336–339 (1923); 3 T. Clarkson, Portraiture of Quakerism 103–104 (3d ed. 1807). The Pennsylvania Militia Act of 1757 exempted from service those "scrupling the use of arms"—a phrase that no one contends had an idiomatic meaning. See 5 Stat. at Large of Pa. 613 (J. Mitchell & H. Flanders comm'rs 1898) (emphasis in original). Thus, the most natural interpretation of Madison's deleted text is that those opposed to carrying weapons for potential violent confrontation would not be "compelled to render military service," in which such carrying would be required.
[p. 591] Finally, Justice Stevens suggests that "keep and bear Arms" was some sort of term of art, presumably akin to "hue and cry" or "cease and desist." (This suggestion usefully evades the problem that there is no evidence whatsoever to support a military reading of "keep arms.") Justice Stevens believes that the unitary meaning of "keep and bear Arms" is established by the Second Amendment's calling it a "right" (singular) rather than "rights" (plural). See post, at 651. There is nothing to this. State constitutions of the founding period routinely grouped multiple (related) guarantees under a singular "right," and the First Amendment protects the "right [singular] of the people peaceably to assemble, and to petition the Government for a redress of grievances." See, e.g., Pa. Declaration of Rights §§IX, XII, XVI, in 5 Thorpe 3083–3084; Ohio Const., Arts. VIII, §§11, 19 (1802), in id., at 2910–2911. And even if "keep and bear Arms" were a unitary phrase, we find no evidence that it bore a military meaning. Although the phrase was not at all common (which would be unusual for a term of art), we have found instances of its use with a clearly nonmilitary connotation. In a 1780 debate in the House of Lords, for example, Lord Richmond described an order to disarm pri- [p. 592] vate citizens (not militia members) as "a violation of the constitutional right of Protestant subjects to keep and bear arms for their own defense." 49 The London Magazine or Gentleman's Monthly Intelligencer 467 (1780). In response, another member of Parliament referred to "the right of bearing arms for personal defence," making clear that no special military meaning for "keep and bear arms" was intended in the discussion. Id., at 467–468.
c. Meaning of the Operative Clause. Putting all of these textual elements together, we find that they guarantee the individual right to possess and carry weapons in case of confrontation. This meaning is strongly confirmed by the historical background of the Second Amendment. We look to this because it has always been widely understood that the Second Amendment, like the First and Fourth Amendments, codified a pre-existing right. The very text of the Second Amendment implicitly recognizes the pre-existence of the right and declares only that it "shall not be infringed." As we said in United States v. Cruikshank, 92 U. S. 542, 553 (1876), "[t]his is not a right granted by the Constitution. Neither is it in any manner dependent upon that instrument for its existence. The Second amendment declares that it shall not be infringed..."
Between the Restoration and the Glorious Revolution, the Stuart Kings Charles II and James II succeeded in using select militias loyal to them to suppress political dissidents, in part by disarming their opponents. See J. Malcolm, To Keep and Bear Arms 31–53 (1994) (hereinafter Malcolm); L. Schwoerer, The Declaration of Rights, 1689, p. 76 (1981). [p. 593] Under the auspices of the 1671 Game Act, for example, the Catholic James II had ordered general disarmaments of regions home to his Protestant enemies. See Malcolm 103–106. These experiences caused Englishmen to be extremely wary of concentrated military forces run by the state and to be jealous of their arms. They accordingly obtained an assurance from William and Mary, in the Declaration of Right (which was codified as the English Bill of Rights), that Protestants would never be disarmed: "That the subjects which are Protestants may have arms for their defense suitable to their conditions and as allowed by law." 1 W. & M., c. 2, §7, in 3 Eng. Stat. at Large 441 (1689). This right has long been understood to be the predecessor to our Second Amendment. See E. Dumbauld, The Bill of Rights and What It Means Today 51 (1957); W. Rawle, A View of the Constitution of the United States of America 122 (1825) (hereinafter Rawle). It was clearly an individual right, having nothing whatever to do with service in a militia. To be sure, it was an individual right not available to the whole population, given that it was restricted to Protestants, and like all written English rights it was held only against the Crown, not Parliament. See Schwoerer, To Hold and Bear Arms: The English Perspective, in Bogus 207, 218; but see 3 J. Story, Commentaries on the Constitution of the United States §1858 (1833) (hereinafter Story) (contending that the "right to bear arms" is a "limitatio[n] upon the power of parliament" as well). But it was secured to them as individuals, according to "libertarian political principles," not as members of a fighting force. Schwoerer, Declaration of Rights, at 283; see also id., at 78; G. Jellinek, The Declaration of the Rights of Man and of Citizens 49, and n. 7 (1901) (reprinted 1979).
By the time of the founding, the right to have arms had become fundamental for English subjects. See Malcolm 122–134. Blackstone, whose works, we have said, "constituted the preeminent authority on English law for the found- [p. 594] ing generation," Alden v. Maine, 527 U.S. 706, 715 (1999), cited the arms provision of the Bill of Rights as one of the fundamental rights of Englishmen. See 1 Blackstone 136, 139–140 (1765). His description of it cannot possibly be thought to tie it to militia or military service. It was, he said, "the natural right of resistance and self preservation," id., at 139, and "the right of having and using arms for self-preservation and defence," id., at 140; see also 3 id., at 2–4 (1768). Other contemporary authorities concurred. See G. Sharp, Tracts, Concerning the Ancient and Only True Legal Means of National Defence, by a Free Militia 17–18, 27 (3d ed. 1782); 2 J. de Lolme, The Rise and Progress of the English Constitution 886–887 (1784) (A. Stephens ed. 1838); W. Blizard, Desultory Reflections on Police 59–60 (1785). Thus, the right secured in 1689 as a result of the Stuarts' abuses was by the time of the founding understood to be an individual right protecting against both public and private violence.
And, of course, what the Stuarts had tried to do to their political enemies, George III had tried to do to the colonists. In the tumultuous decades of the 1760's and 1770's, the Crown began to disarm the inhabitants of the most rebellious areas. That provoked polemical reactions by Americans invoking their rights as Englishmen to keep arms. A New York article of April 1769 said that "[i]t is a natural right which the people have reserved to themselves, confirmed by the Bill of Rights, to keep arms for their own defence." A Journal of the Times: Mar. 17, New York Journal, Supp. 1, Apr. 13, 1769, in Boston Under Military Rule 79 (O. Dickerson ed. 1936); see also, e.g., Shippen, Boston Gazette, Jan. 30, 1769, in 1 The Writings of Samuel Adams 299 (H. Cushing ed. 1968). They understood the right to enable individuals to defend themselves. As the most important early American edition of Blackstone's Commentaries (by the law professor and former Antifederalist St. George Tucker) made clear in the notes to the [p. 595] description of the arms right, Americans understood the "right of self-preservation" as permitting a citizen to "repe[l] force by force" when "the intervention of society in his behalf, may be too late to prevent an injury." 1 Blackstone's Commentaries 145–146, n. 42 (1803) (hereinafter Tucker's Blackstone). See also W. Duer, Outlines of the Constitutional Jurisprudence of the United States 31–32 (1833).
There seems to us no doubt, on the basis of both text and history, that the Second Amendment conferred an individual right to keep and bear arms. Of course the right was not unlimited, just as the First Amendment's right of free speech was not, see, e.g., United States v. Williams, 553 U.S. 285 (2008). Thus, we do not read the Second Amendment to protect the right of citizens to carry arms for any sort of confrontation, just as we do not read the First Amendment to protect the right of citizens to speak for any purpose. Before turning to limitations upon the individual right, however, we must determine whether the prefatory clause of the Second Amendment comports with our interpretation of the operative clause.
2. Prefatory Clause.
The prefatory clause reads: "A well regulated Militia, being necessary to the security of a free State...."
a. "Well-Regulated Militia." In United States v. Miller, 307 U.S. 174, 179 (1939), we explained that "the Militia comprised all males physically capable of acting in concert for the common defense." That definition comports with founding-era sources. See, e.g., Webster ("The militia of a country are the able bodied men organized into companies, regiments and brigades … and required by law to attend military exercises on certain days only, but at other times left to pursue their usual occupations"); The Federalist No. 46, pp. 329, 334 (B. Wright ed. 1961) (J. Madison) ("near half a million of citizens with arms in their hands"); Letter to Destutt de Tracy (Jan. 26, 1811), in The Portable Thomas [p. 596] Jefferson 520, 524 (M. Peterson ed. 1975) ("[T]he militia of the State, that is to say, of every man in it able to bear arms").
Petitioners take a seemingly narrower view of the militia, stating that "[m]ilitias are the state- and congressionally- regulated military forces described in the Militia Clauses (art. I, §8, cls. 15–16)." Brief for Petitioners 12. Although we agree with petitioners' interpretive assumption that "militia" means the same thing in Article I and the Second Amendment, we believe that petitioners identify the wrong thing, namely, the organized militia. Unlike armies and navies, which Congress is given the power to create ("to raise...Armies"; "to provide...a Navy," Art. I, §8, cls. 12–13), the militia is assumed by Article I already to be in existence. Congress is given the power to "provide for calling forth the militia," §8, cl. 15; and the power not to create, but to "organiz[e]" it—and not to organize "a" militia, which is what one would expect if the militia were to be a federal creation, but to organize "the" militia, connoting a body already in existence, Ibid., cl. 16. This is fully consistent with the ordinary definition of the militia as all able-bodied men. From that pool, Congress has plenary power to organize the units that will make up an effective fighting force. That is what Congress did in the first militia Act, which specified that "each and every free able-bodied white male citizen of the respective states, resident therein, who is or shall be of the age of eighteen years, and under the age of forty-five years (except as is herein after excepted) shall severally and respectively be enrolled in the militia." Act of May 8, 1792, 1 Stat. 271. To be sure, Congress need not conscript every able-bodied man into the militia, because nothing in Article I suggests that in exercising its power to organize, discipline, and arm the militia, Congress must focus upon the entire body. Although the militia consists of all ablebodied men, the federally organized militia may consist of a subset of them.
[p. 597] Finally, the adjective "well-regulated" implies nothing more than the imposition of proper discipline and training. See Johnson 1619 ("Regulate": "To adjust by rule or method"); Rawle 121–122; cf. Va. Declaration of Rights §13 (1776), in 7 Thorpe 3812, 3814 (referring to "a well-regulated militia, composed of the body of the people, trained to arms").
b. "Security of a Free State."
The phrase "security of a free state" meant "security of a free polity," not security of each of the several States as the dissent below argued, see 478 F.3d, at 405, and n. 10. Joseph Story wrote in his treatise on the Constitution that "the word 'state' is used in various senses [and in] its most enlarged sense, it means the people composing a particular nation or community." 1 Story §208; see also 3 id., §1890 (in reference to the Second Amendment's prefatory clause: "The militia is the natural defence of a free country"). It is true that the term "State" elsewhere in the Constitution refers to individual States, but the phrase "security of a free state" and close variations seem to have been terms of art in 18th-century political discourse, meaning a "'free country'" or free polity. See Volokh, "Necessary to the Security of a Free State," 83 Notre Dame L. Rev. 1, 5 (2007); see, e.g., 4 Blackstone 151 (1769); Brutus Essay III (Nov. 15, 1787), in The Essential Antifederalist 251, 253 (W. Allen & G. Lloyd eds., 2d ed. 2002). Moreover, the other instances of "state" in the Constitution are typically accompanied by modifiers making clear that the reference is to the several States—"each state," "several states," "any state," "that state," "particular states," "one state," "no state." And the presence of the term "foreign state" in Article I and Article III shows that the word "state" did not have a single meaning in the Constitution.
There are many reasons why the militia was thought to be "necessary to the security of a free state." See 3 Story §1890. First, of course, it is useful in repelling invasions and suppressing insurrections. Second, it renders large [p. 598] standing armies unnecessary—an argument that Alexander Hamilton made in favor of federal control over the militia. The Federalist No. 29, pp. 226, 227 (B. Wright ed. 1961) (A. Hamilton). Third, when the able-bodied men of a nation are trained in arms and organized, they are better able to resist tyranny.
3. Relationship between Prefatory Clause and Operative Clause
We reach the question, then: Does the preface fit with an operative clause that creates an individual right to keep and bear arms? It fits perfectly, once one knows the history that the founding generation knew and that we have described above. That history showed that the way tyrants had eliminated a militia consisting of all the ablebodied men was not by banning the militia but simply by taking away the people's arms, enabling a select militia or standing army to suppress political opponents. This is what had occurred in England that prompted codification of the right to have arms in the English Bill of Rights. The debate with respect to the right to keep and bear arms, as with other guarantees in the Bill of Rights, was not over whether it was desirable (all agreed that it was) but over whether it needed to be codified in the Constitution. During the 1788 ratification debates, the fear that the federal government would disarm the people in order to impose rule through a standing army or select militia was pervasive in Antifederalist rhetoric. See, e.g., Letters from The Federal Farmer III (Oct. 10, 1787), in 2 The Complete Anti-Federalist 234, 242 (H. Storing ed. 1981). John Smilie, for example, worried not only that Congress's "command of the militia" could be used to create a "select militia," or to have "no militia at all," but also, as a separate concern, that "[w]hen a select militia is formed; the people in general may be disarmed." 2 Documentary History of the Ratification of the Constitution 508–509 (M. Jensen ed. 1976) (hereinafter [p. 599] Documentary Hist.). Federalists responded that because Congress was given no power to abridge the ancient right of individuals to keep and bear arms, such a force could never oppress the people. See, e.g., A Pennsylvanian III (Feb. 20, 1788), in The Origin of the Second Amendment 275, 276 (D. Young ed., 2d ed. 2001) (hereinafter Young); White, To the Citizens of Virginia, Feb. 22, 1788, in id., at 280, 281; A Citizen of America, (Oct. 10, 1787) in id., at 38, 40; Remarks on the Amendments to the federal Constitution, Nov. 7, 1788, in id., at 556. It was understood across the political spectrum that the right helped to secure the ideal of a citizen militia, which might be necessary to oppose an oppressive military force if the constitutional order broke down.
It is therefore entirely sensible that the Second Amendment's prefatory clause announces the purpose for which the right was codified: to prevent elimination of the militia. The prefatory clause does not suggest that preserving the militia was the only reason Americans valued the ancient right; most undoubtedly thought it even more important for self-defense and hunting. But the threat that the new Federal Government would destroy the citizens' militia by taking away their arms was the reason that right—unlike some other English rights—was codified in a written Constitution. Justice Breyer's assertion that individual self-defense is merely a "subsidiary interest" of the right to keep and bear arms, see post, at 714, is profoundly mistaken. He bases that assertion solely upon the prologue—but that can only show that self-defense had little to do with the right's codification; it was the central component of the right itself.
Besides ignoring the historical reality that the Second Amendment was not intended to lay down a "novel principl[e]" but rather codified a right "inherited from our English ancestors," Robertson v. Baldwin, 165 U.S. 275, 281 (1897), petitioners' interpretation does not even achieve the nar- [p. 600] rower purpose that prompted codification of the right. If, as they believe, the Second Amendment right is no more than the right to keep and use weapons as a member of an organized militia, see Brief for Petititioners 8—if, that is, the organized militia is the sole institutional beneficiary of the Second Amendment's guarantee—it does not assure the existence of a "citizens' militia" as a safeguard against tyranny. For Congress retains plenary authority to organize the militia, which must include the authority to say who will belong to the organized force. That is why the first Militia Act's requirement that only whites enroll caused States to amend their militia laws to exclude free blacks. See Siegel, The Federal Government's Power to Enact Color-Conscious Laws, 92 Nw. U. L. Rev. 477, 521–525 (1998). Thus, if petitioners are correct, the Second Amendment protects citizens' right to use a gun in an organization from which Congress has plenary authority to exclude them. It guarantees a select militia of the sort the Stuart kings found useful, but not the people's militia that was the concern of the founding generation.

##### B

Our interpretation is confirmed by analogous arms-bearing rights in state constitutions that preceded and im- [p. 601] mediately followed adoption of the Second Amendment. Four States adopted analogues to the Federal Second Amendment in the period between independence and the ratification of the Bill of Rights. Two of them—Pennsylvania and Vermont—clearly adopted individual rights unconnected to militia service. Pennsylvania's Declaration of Rights of 1776 said: "That the people have a right to bear arms for the defence of themselves, and the state...." §XIII, in 5 Thorpe 3082, 3083 (emphasis added). In 1777, Vermont adopted the identical provision, except for inconsequential differences in punctuation and capitalization. See Vt. Const., ch. 1, §15, in 6 id., at 3741.
North Carolina also codified a right to bear arms in 1776: "That the people have a right to bear arms, for the defence of the State...." Declaration of Rights §XVII, in id., at 2787, 2788. This could plausibly be read to support only a right to bear arms in a militia—but that is a peculiar way to make the point in a constitution that elsewhere repeatedly mentions the militia explicitly. See §§14, 18, 35, in 5 id., 2789, 2791, 2793. Many colonial statutes required individual arms-bearing for public-safety reasons—such as the 1770 Georgia law that "for the security and defence of this province from internal dangers and insurrections" required those men who qualified for militia duty individually "to carry fire arms" "to places of public worship." 19 Colonial Records of the State of Georgia 137–139 (A. Candler ed. 1911 (pt. 2)) (emphasis added). That broad public-safety understanding was the connotation given to the North Carolina right by that State's Supreme Court in 1843. See State v. Huntly, 3 Ired. 418, 422–423.
The 1780 Massachusetts Constitution presented another variation on the theme: "The people have a right to keep and to bear arms for the common defence. …" Pt. First, Art. XVII, in 3 Thorpe 1888, 1892. Once again, if one gives narrow meaning to the phrase "common defence" this can be thought to limit the right to the bearing of arms in a [p. 602] state-organized military force. But once again the State's highest court thought otherwise. Writing for the court in an 1825 libel case, Chief Justice Parker wrote: "The liberty of the press was to be unrestrained, but he who used it was to be responsible in cases of its abuse; like the right to keep fire arms, which does not protect him who uses them for annoyance or destruction." Commonwealth v. Blanding, 20 Mass. 304, 313–314. The analogy makes no sense if firearms could not be used for any individual purpose at all. See also Kates, Handgun Prohibition and the Original Meaning of the Second Amendment, 82 Mich. L. Rev. 204, 244 (1983) (19th-century courts never read "common defence" to limit the use of weapons to militia service).
We therefore believe that the most likely reading of all four of these pre-Second Amendment state constitutional provisions is that they secured an individual right to bear arms for defensive purposes. Other States did not include rights to bear arms in their pre-1789 constitutions—although in Virginia a Second Amendment analogue was proposed (unsuccessfully) by Thomas Jefferson. (It read: "No freeman shall ever be debarred the use of arms [within his own lands or tenements]." 1 The Papers of Thomas Jefferson 344 (J. Boyd ed. 1950)).
Between 1789 and 1820, nine States adopted Second Amendment analogues. Four of them—Kentucky, Ohio, Indiana, and Missouri—referred to the right of the people to "bear arms in defence of themselves and the State." See n. 8, supra. Another three States—Mississippi, Connecticut, and Alabama—used the even more individualistic phrasing that each citizen has the "right to bear arms in defence of himself and the State." See Ibid. Finally, two States—Tennessee and Maine—used the "common defence" language [p. 603] of Massachusetts. See Tenn. Const., Art. XI, §26 (1796), in 6 Thorpe 3414, 3424; Me. Const., Art. I, §16 (1819), in 3 id., at 1646, 1648. That of the nine state constitutional protections for the right to bear arms enacted immediately after 1789 at least seven unequivocally protected an individual citizen's right to self-defense is strong evidence that that is how the founding generation conceived of the right. And with one possible exception that we discuss in Part II–D–2, 19th-century courts and commentators interpreted these state constitutional provisions to protect an individual right to use arms for self-defense. See n. 9, supra; Simpson v. State, 5 Yer. 356, 360 (Tenn. 1833).
The historical narrative that petitioners must endorse would thus treat the Federal Second Amendment as an odd outlier, protecting a right unknown in state constitutions or at English common law, based on little more than an overreading of the prefatory clause.

Justice Stevens relies on the drafting history of the Second Amendment—the various proposals in the state conventions and the debates in Congress. It is dubious to rely on such history to interpret a text that was widely understood to codify a pre-existing right, rather than to fashion a new one. But even assuming that this legislative history is relevant, Justice Stevens flatly misreads the historical record.
It is true, as Justice Stevens says, that there was concern that the Federal Government would abolish the institution of the state militia. See post, at 655. That concern found expression, however, not in the various Second Amendment precursors proposed in the State conventions, but in separate structural provisions that would have given the States concurrent and seemingly nonpre-emptible authority to organize, discipline, and arm the militia when the Federal Government failed to do so. See Veit 17, 20 (Virginia proposal); 4 J. Eliot, The Debates in the Several State [p. 604] Conventions on the Adoption of the Federal Constitution 244, 245 (2d ed. 1836) (reprinted 1941) (North Carolina proposal); see also 2 Documentary Hist. 624 (Pennsylvania minority's proposal). The Second Amendment precursors, by contrast, referred to the individual English right already codified in two (and probably four) State constitutions. The Federalist-dominated first Congress chose to reject virtually all major structural revisions favored by the Antifederalists, including the proposed militia amendments. Rather, it adopted primarily the popular and uncontroversial (though, in the Federalists' view, unnecessary) individual-rights amendments. The Second Amendment right, protecting only individuals' liberty to keep and carry arms, did nothing to assuage Antifederalists' concerns about federal control of the militia. See, e.g., Centinel, Revived, No. XXIX, Philadelphia Independent Gazetteer, Sept. 9, 1789, in Young 711, 712.
Justice Stevens thinks it significant that the Virginia, New York, and North Carolina Second Amendment proposals were "embedded...within a group of principles that are distinctly military in meaning," such as statements about the danger of standing armies. Post, at 657. But so was the highly influential minority proposal in Pennsylvania, yet that proposal, with its reference to hunting, plainly referred to an individual right. See 2 Documentary Hist. 624. Other than that erroneous point, Justice Stevens has brought forward absolutely no evidence that those proposals conferred only a right to carry arms in a militia. By contrast, New Hampshire's proposal, the Pennsylvania minority's proposal, and Samuel Adams' proposal in Massachusetts unequivocally referred to individual rights, as did two state constitutional provisions at the time. See Veit 16, 17 (New Hampshire proposal); 6 Documentary Hist. 1452, 1453 (J. Kaminski & G. Saladino eds. 2000) (Samuel Adams' proposal). Justice Stevens' view thus relies on the proposition, unsupported by any evidence, that different people of the founding period [p. 605] had vastly different conceptions of the right to keep and bear arms. That simply does not comport with our longstanding view that the Bill of Rights codified venerable, widely understood liberties.

##### D

We now address how the Second Amendment was interpreted from immediately after its ratification through the end of the 19th century. Before proceeding, however, we take issue with Justice Stevens' equating of these sources with postenactment legislative history, a comparison that betrays a fundamental misunderstanding of a court's interpretive task. See post, at 662, n. 28. "Legislative history," of course, refers to the pre-enactment statements of those who drafted or voted for a law; it is considered persuasive by some, not because they reflect the general understanding of the disputed terms, but because the legislators who heard or read those statements presumably voted with that understanding. Ibid. "Postenactment legislative history," ibid., a deprecatory contradiction in terms, refers to statements of those who drafted or voted for the law that are made after its enactment and hence could have had no effect on the congressional vote. It most certainly does not refer to the examination of a variety of legal and other sources to determine the public understanding of a legal text in the period after its enactment or ratification. That sort of inquiry is a critical tool of constitutional interpretation. As we will show, virtually all interpreters of the Second Amendment in the century after its enactment interpreted the amendment as we do.
1. Postratification Commentary
Three important founding-era legal scholars interpreted the Second Amendment in published writings. All three understood it to protect an individual right unconnected with militia service.
[p. 606] St. George Tucker's version of Blackstone's Commentaries, as we explained above, conceived of the Blackstonian arms right as necessary for self-defense. He equated that right, absent the religious and class-based restrictions, with the Second Amendment. See 2 Tucker's Blackstone 143. In Note D, entitled, "View of the Constitution of the United States," Tucker elaborated on the Second Amendment: "This may be considered as the true palladium of liberty.... The right to self-defence is the first law of nature: in most governments it has been the study of rulers to confine the right within the narrowest limits possible. Wherever standing armies are kept up, and the right of the people to keep and bear arms is, under any colour or pretext whatsoever, prohibited, liberty, if not already annihilated, is on the brink of destruction." 1 id., at App. 300 (ellipsis in original). He believed that the English game laws had abridged the right by prohibiting "keeping a gun or other engine for the destruction of game." Ibid; see also 2 id., at 143, and nn. 40 and 41. He later grouped the right with some of the individual rights included in the First Amendment and said that if "a law be passed by congress, prohibiting" any of those rights, it would "be the province of the judiciary to pronounce whether any such act were constitutional, or not; and if not, to acquit the accused...." 1 id., at App. 357. It is unlikely that Tucker was referring to a person's being "accused" of violating a law making it a crime to bear arms in a state militia.
In 1825, William Rawle, a prominent lawyer who had been a member of the Pennsylvania Assembly that ratified the Bill of Rights, published an influential treatise, which analyzed the Second Amendment as follows:
   "The first [principle] is a declaration that a well regulated militia is necessary to the security of a free state; a proposition from which few will dissent....
   "The corollary, from the first position is, that the right of the people to keep and bear arms shall not be infringed.
   "The prohibition is general. No clause in the constitution could by any rule of construction be conceived to give to congress a power to disarm the people. Such a flagitious attempt could only be made under some general pretence by a state legislature. But if in any blind pursuit of inordinate power, either should attempt it, this amendment may be appealed to as a restraint on both." Rawle 121–122.
Like Tucker, Rawle regarded the English game laws as violating the right codified in the Second Amendment. See id., 122–123. Rawle clearly differentiated between the people's right to bear arms and their service in a militia: "In a people permitted and accustomed to bear arms, we have the rudiments of a militia, which properly consists of armed citizens, divided into military bands, and instructed at least in part, in the use of arms for the purposes of war." Id., at 140. Rawle further said that the Second Amendment right ought not "be abused to the disturbance of the public peace," such as by assembling with other armed individuals "for an [p. 608] unlawful purpose"—statements that make no sense if the right does not extend to any individual purpose.
Joseph Story published his famous Commentaries on the Constitution of the United States in 1833. Justice Stevens suggests that "[t]here is not so much as a whisper" in Story's explanation of the Second Amendment that favors the individual-rights view. Post, at 668. That is wrong. Story explained that the English Bill of Rights had also included a "right to bear arms," a right that, as we have discussed, had nothing to do with militia service. 3 Story §1858. He then equated the English right with the Second Amendment:
   "§1891. A similar provision [to the Second Amendment] in favour of protestants (for to them it is confined) is to be found in the bill of rights of 1688, it being declared, 'that the subjects, which are protestants, may have arms for their defence suitable to their condition, and as allowed by law.' But under various pretences the effect of this provision has been greatly narrowed; and it is at present in England more nominal than real, as a defensive privilege." (Footnotes omitted.)
This comparison to the Declaration of Right would not make sense if the Second Amendment right was the right to use a gun in a militia, which was plainly not what the English right protected. As the Tennessee Supreme Court recognized 38 years after Story wrote his Commentaries, "[t]he passage from Story, shows clearly that this right was intended...and was guaranteed to, and to be exercised and enjoyed by the citizen as such, and not by him as a soldier, or in defense solely of his political rights." Andrews v. State, 50 Tenn. 165, 183 (1871). Story's Commentaries also cite as support Tucker and Rawle, both of whom clearly viewed the right as unconnected to militia service. See 3 Story §1890, n. 2; §1891, n. 3. In addition, in a shorter 1840 work Story wrote: "One of the ordinary modes, by which [p. 609] tyrants accomplish their purposes without resistance, is, by disarming the people, and making it an offence to keep arms, and by substituting a regular army in the stead of a resort to the militia." A Familiar Exposition of the Constitution of the United States §450 (reprinted in 1986).
Antislavery advocates routinely invoked the right to bear arms for self-defense. Joel Tiffany, for example, citing Blackstone's description of the right, wrote that "the right to keep and bear arms, also implies the right to use them if necessary in self defence; without this right to use the guaranty would have hardly been worth the paper it consumed." A Treatise on the Unconstitutionality of American Slavery 117–118 (1849); see also L. Spooner, The Unconstitutionality of Slavery 116 (1845) (right enables "personal defence"). In his famous Senate speech about the 1856 "Bleeding Kansas" conflict, Charles Sumner proclaimed:
   "The rifle has ever been the companion of the pioneer and, under God, his tutelary protector against the red man and the beast of the forest. Never was this efficient weapon more needed in just self-defence, than now in Kansas, and at least one article in our National Constitution must be blotted out, before the complete right to it can in any way be impeached. And yet such is the madness of the hour, that, in defiance of the solemn guarantee, embodied in the Amendments to the Constitution, that 'the right of the people to keep and bear arms shall not be infringed,' the people of Kansas have been arraigned for keeping and bearing them, and the Senator from South Carolina has had the face to say openly, on this floor, that they should be disarmed—of course, that the fanatics of Slavery, his allies and constituents, may meet no impediment." The Crime Against Kansas, May 19–20, 1856, in American Speeches: Political Oratory from the Revolution to the Civil War 553, 606–607 (2006).
[p. 610] We have found only one early 19th-century commentator who clearly conditioned the right to keep and bear arms upon service in the militia—and he recognized that the prevailing view was to the contrary. "The provision of the constitution, declaring the right of the people to keep and bear arms, &c. was probably intended to apply to the right of the people to bear arms for such [militia-related] purposes only, and not to prevent congress or the legislatures of the different states from enacting laws to prevent the citizens from always going armed. A different construction however has been given to it." B. Oliver, The Rights of an American Citizen 177 (1832).
2. Pre-Civil War Case Law
The 19th-century cases that interpreted the Second Amendment universally support an individual right unconnected to militia service. In Houston v. Moore, 5 Wheat. 1, 24 (1820), this Court held that States have concurrent power over the militia, at least where not preempted by Congress. Agreeing in dissent that States could "organize, discipline, and arm" the militia in the absence of conflicting federal regulation, Justice Story said that the Second Amendment "may not, perhaps, be thought to have any important bearing on this point. If it have, it confirms and illustrates, rather than impugns the reasoning already suggested." Id., at 51–53. Of course, if the Amendment simply "protect[ed] the right of the people of each of the several States to maintain a well-regulated militia," post, at 637 (Stevens, J., dissenting), it would have enormous and obvious bearing on the point. But the Court and Story derived the States' power over the militia from the nonexclusive nature of federal power, not from the Second Amendment, whose preamble merely "confirms and illustrates" the importance of the militia. Even clearer was Justice Baldwin. In the famous fugitive-slave case of Johnson v. Tompkins, 13 F. Cas. 840, [p. 611] 850, 852 (CC Pa. 1833), Baldwin, sitting as a circuit judge, cited both the Second Amendment and the Pennsylvania analogue for his conclusion that a citizen has "a right to carry arms in defence of his property or person, and to use them, if either were assailed with such force, numbers or violence as made it necessary for the protection or safety of either."
Many early 19th-century state cases indicated that the Second Amendment right to bear arms was an individual right unconnected to militia service, though subject to certain restrictions. A Virginia case in 1824 holding that the Constitution did not extend to free blacks explained that "numerous restrictions imposed on [blacks] in our Statute Book, many of which are inconsistent with the letter and spirit of the Constitution, both of this State and of the United States as respects the free whites, demonstrate, that, here, those instruments have not been considered to extend equally to both classes of our population. We will only instance the restriction upon the migration of free blacks into this State, and upon their right to bear arms." Aldridge v. Commonwealth, 2 Va. Cas. 447, 449 (Gen. Ct.). The claim was obviously not that blacks were prevented from carrying guns in the militia. See also Waters v. State, 1 Gill 302, 309 (Md. [p. 612] 1843) (because free blacks were treated as a "dangerous population," "laws have been passed to prevent their migration into this State; to make it unlawful for them to bear arms; to guard even their religious assemblages with peculiar watchfulness"). An 1829 decision by the Supreme Court of Michigan said: "The constitution of the United States also grants to the citizen the right to keep and bear arms. But the grant of this privilege cannot be construed into the right in him who keeps a gun to destroy his neighbor. No rights are intended to be granted by the constitution for an unlawful or unjustifiable purpose." United States v. Sheldon, in 5 Transactions of the Supreme Court of the Territory of Michigan 337, 346 (W. Blume ed. 1940) (hereinafter Blume). It is not possible to read this as discussing anything other than an individual right unconnected to militia service. If it did have to do with militia service, the limitation upon it would not be any "unlawful or unjustifiable purpose," but any nonmilitary purpose whatsoever.
In Nunn v. State, 1 Ga. 243, 251 (1846), the Georgia Supreme Court construed the Second Amendment as protecting the "natural right of self-defence" and therefore struck down a ban on carrying pistols openly. Its opinion perfectly captured the way in which the operative clause of the Second Amendment furthers the purpose announced in the prefatory clause, in continuity with the English right:
   "The right of the whole people, old and young, men, women and boys, and not militia only, to keep and bear arms of every description, and not such merely as are used by the militia, shall not be infringed, curtailed, or broken in upon, in the smallest degree; and all this for the important end to be attained: the rearing up and qualifying a well-regulated militia, so vitally necessary [p. 613] to the security of a free State. Our opinion is, that any law, State or Federal, is repugnant to the Constitution, and void, which contravenes this right, originally belonging to our forefathers, trampled under foot by Charles I. and his two wicked sons and successors, re-established by the revolution of 1688, conveyed to this land of liberty by the colonists, and finally incorporated conspicuously in our own Magna Charta!"
Likewise, in State v. Chandler, 5 La. Ann. 489, 490 (1850), the Louisiana Supreme Court held that citizens had a right to carry arms openly: "This is the right guaranteed by the Constitution of the United States, and which is calculated to incite men to a manly and noble defence of themselves, if necessary, and of their country, without any tendency to secret advantages and unmanly assassinations."
Those who believe that the Second Amendment preserves only a militia-centered right place great reliance on the Tennessee Supreme Court's 1840 decision in Aymette v. State, 21 Tenn. 154. The case does not stand for that broad proposition; in fact, the case does not mention the word "militia" at all, except in its quoting of the Second Amendment. Aymette held that the state constitutional guarantee of the right to "bear" arms did not prohibit the banning of concealed weapons. The opinion first recognized that both the state right and the federal right were descendents of the 1689 English right, but (erroneously, and contrary to virtually all other authorities) read that right to refer only to "protect[ion of] the public liberty" and "keep[ing] in awe those in power," id., at 158. The court then adopted a sort of middle position, whereby citizens were permitted to carry arms openly, unconnected with any service in a formal militia, but were given the right to use them only for the military purpose of banding together to oppose tyranny. This odd reading of the right is, to be sure, not the one we adopt—but it is not petitioners' reading either. More importantly, seven years earlier the Tennessee Supreme Court [p. 614] had treated the state constitutional provision as conferring a right "of all the free citizens of the State to keep and bear arms for their defence," Simpson, 5 Yer., at 360; and 21 years later the court held that the "keep" portion of the state constitutional right included the right to personal self-defense: "[T]he right to keep arms involves, necessarily, the right to use such arms for all the ordinary purposes, and in all the ordinary modes usual in the country, and to which arms are adapted, limited by the duties of a good citizen in times of peace." Andrews, 50 Tenn., at 178; see also Ibid. (equating state provision with Second Amendment).
3. Post-Civil War Legislation.
In the aftermath of the Civil War, there was an outpouring of discussion of the Second Amendment in Congress and in public discourse, as people debated whether and how to secure constitutional rights for newly free slaves. See generally S. Halbrook, Freedmen, the Fourteenth Amendment, and the Right to Bear Arms, 1866–1876 (1998) (hereinafter Halbrook); Brief for Institute for Justice as Amicus Curiae. Since those discussions took place 75 years after the ratification of the Second Amendment, they do not provide as much insight into its original mean ing as earlier sources. Yet those born and educated in the early 19th century faced a widespread effort to limit arms ownership by a large number of citizens; their understanding of the origins and continuing significance of the Amendment is instructive.
Blacks were routinely disarmed by Southern States after the Civil War. Those who opposed these injustices frequently stated that they infringed blacks' constitutional right to keep and bear arms. Needless to say, the claim was not that blacks were being prohibited from carrying arms in an organized state militia. A Report of the Commission of the Freedmen's Bureau in 1866 stated plainly: "[T]he civil law [of Kentucky] prohibits the colored man from bearing arms.... Their arms are taken from them by the civil [p. 615] authorities.... Thus, the right of the people to keep and bear arms as provided in the Constitution is infringed." H. R. Exec. Doc. No. 70, 39th Cong., 1st Sess., 233, 236. A joint congressional Report decried:
   "in some parts of [South Carolina], armed parties are, without proper authority, engaged in seizing all firearms found in the hands of the freemen. Such conduct is in clear and direct violation of their personal rights as guaranteed by the Constitution of the United States, which declares that 'the right of the people to keep and bear arms shall not be infringed.' The freedmen of South Carolina have shown by their peaceful and orderly conduct that they can safely be trusted with fire-arms, and they need them to kill game for subsistence, and to protect their crops from destruction by birds and animals." Joint Comm. on Reconstruction, H. R. Rep. No. 30, 39th Cong., 1st Sess., pt. 2, p. 229 (1866) (Proposed Circular of Brigadier General R. Saxton).
The view expressed in these statements was widely reported and was apparently widely held. For example, an editorial in The Loyal Georgian (Augusta) on February 3, 1866, assured blacks that "[a]ll men, without distinction of color, have the right to keep and bear arms to defend their homes, families or themselves." Halbrook 19.
Congress enacted the Freedmen's Bureau Act on July 16, 1866. Section 14 stated:
   "[T]he right...to have full and equal benefit of all laws and proceedings concerning personal liberty, personal security, and the acquisition, enjoyment, and disposition of estate, real and personal, including the constitutional right to bear arms, shall be secured to and enjoyed by all the citizens...without respect to race or color, or previous condition of slavery...." 14 Stat. 176–177.
The understanding that the Second Amendment gave freed blacks the right to keep and bear arms was reflected in con- [p. 616] gressional discussion of the bill, with even an opponent of it saying that the founding generation "were for every man bearing his arms about him and keeping them in his house, his castle, for his own defense." Cong. Globe, 39th Cong., 1st Sess., 362, 371 (1866) (Sen. Davis).
Similar discussion attended the passage of the Civil Rights Act of 1871 and the Fourteenth Amendment. For example, Representative Butler said of the Act: "Section eight is intended to enforce the well-known constitutional provision guaranteeing the right of the citizen to 'keep and bear arms,' and provides that whoever shall take away, by force or violence, or by threats and intimidation, the arms and weapons which any person may have for his defense, shall be deemed guilty of larceny of the same." H. R. Rep. No. 37, 41st Cong., 3d Sess., pp. 7–8 (1871). With respect to the proposed Amendment, Senator Pomeroy described as one of the three "indispensable" "safeguards of liberty...under the Constitution" a man's "right to bear arms for the defense of himself and family and his homestead." Cong. Globe, 39th Cong., 1st Sess., 1182 (1866). Representative Nye thought the Fourteenth Amendment unnecessary because "[a]s citizens of the United States [blacks] have equal right to protection, and to keep and bear arms for self-defense." Id., at 1073 (1866).
It was plainly the understanding in the post-Civil War Congress that the Second Amendment protected an individual right to use arms for self-defense.
4. Post-Civil War Commentators.
Every late-19th-century legal scholar that we have read interpreted the Second Amendment to secure an individual right unconnected with militia service. The most famous was the judge and professor Thomas Cooley, who wrote a massively popular 1868 Treatise on Constitutional Limitations. Concerning the Second Amendment it said:
   "Among the other defences to personal liberty should be mentioned the right of the people to keep and bear [p. 617] arms.... The alternative to a standing army is 'a well-regulated militia,' but this cannot exist unless the people are trained to bearing arms. How far it is in the power of the legislature to regulate this right, we shall not undertake to say, as happily there has been very little occasion to discuss that subject by the courts." Id., at 350.
That Cooley understood the right not as connected to militia service, but as securing the militia by ensuring a populace familiar with arms, is made even clearer in his 1880 work, General Principles of Constitutional Law. The Second Amendment, he said, "was adopted with some modification and enlargement from the English Bill of Rights of 1688, where it stood as a protest against arbitrary action of the overturned dynasty in disarming the people." Id., at 270. In a section entitled "The Right in General," he continued:
   "It might be supposed from the phraseology of this provision that the right to keep and bear arms was only guaranteed to the militia; but this would be an interpretation not warranted by the intent. The militia, as has been elsewhere explained, consists of those persons who, under the law, are liable to the performance of military duty, and are officered and enrolled for service when called upon. But the law may make provision for the enrolment of all who are fit to perform military duty, or of a small number only, or it may wholly omit to make any provision at all; and if the right were limited to those enrolled, the purpose of this guaranty might be defeated altogether by the action or neglect to act of the government it was meant to hold in check. The meaning of the provision undoubtedly is, that the people, from whom the militia must be taken, shall have the right to keep and bear arms; and they need no permission or regulation of law for the purpose. But this enables government to have a well regulated militia; for to bear arms implies something more than the mere keeping; it [p. 618] implies the learning to handle and use them in a way that makes those who keep them ready for their efficient use; in other words, it implies the right to meet for voluntary discipline in arms, observing in doing so the laws of public order." Id., at 271.
All other post-Civil War 19th-century sources we have found concurred with Cooley. One example from each decade will convey the general flavor:
   "[The purpose of the Second Amendment is] to secure a well-armed militia. … But a militia would be useless unless the citizens were enabled to exercise themselves in the use of warlike weapons. To preserve this privilege, and to secure to the people the ability to oppose themselves in military force against the usurpations of government, as well as against enemies from without, that government is forbidden by any law or proceeding to invade or destroy the right to keep and bear arms. … The clause is analogous to the one securing the freedom of speech and of the press. Freedom, not license, is secured; the fair use, not the libellous abuse, is protected." J. Pomeroy, An Introduction to the Constitutional Law of the United States 152–153 (1868) (hereinafter Pomeroy).
   "As the Constitution of the United States, and the constitutions of several of the states, in terms more or less comprehensive, declare the right of the people to keep and bear arms, it has been a subject of grave discussion, in some of the state courts, whether a statute prohibiting persons, when not on a journey, or as travellers, from wearing or carrying concealed weapons, be constitutional. There has been a great difference of opinion on the question." 2 J. Kent, Commentaries on American Law *340, n. 2 (O. Holmes ed., 12th ed. 1873) (hereinafter Kent).
   "Some general knowledge of firearms is important to the public welfare; because it would be impossible, in case of war, to organize promptly an efficient force of volunteers unless the people had some familiarity with weapons of war. The Constitution secures the right of the people to keep and bear arms. No doubt, a citizen who keeps a gun or pistol under judicious precautions, practices in safe places the use of it, and in due time teaches his sons to do the same, exercises his individual right. No doubt, a person whose residence or duties involve peculiar peril may keep a pistol for prudent self-defence." B. Abbott, Judge and Jury: A Popular Explanation of the Leading Topics in the Law of the Land 333 (1880) (hereinafter Abbott).
   "The right to bear arms has always been the distinctive privilege of freemen. Aside from any necessity of self-protection to the person, it represents among all nations power coupled with the exercise of a certain jurisdiction.... [I]t was not necessary that the right to bear arms should be granted in the Constitution, for it had always existed." J. Ordronaux, Constitutional Legislation in the United States 241–242 (1891).

##### E

We now ask whether any of our precedents forecloses the conclusions we have reached about the meaning of the Second Amendment.
United States v. Cruikshank, 92 U.S. 542, in the course of vacating the convictions of members of a white mob for depriving blacks of their right to keep and bear arms, held that the Second Amendment does not by its own force apply to anyone other than the Federal Government. The opinion explained that the right "is not a right granted by the Constitution [or] in any manner dependent upon that instrument for its existence. The second amendment...means no more [p. 620] than that it shall not be infringed by Congress." Id., at 553. States, we said, were free to restrict or protect the right under their police powers. The limited discussion of the Second Amendment in Cruikshank supports, if anything, the individual-rights interpretation. There was no claim in Cruikshank that the victims had been deprived of their right to carry arms in a militia; indeed, the Governor had disbanded the local militia unit the year before the mob's attack, see C. Lane, The Day Freedom Died 62 (2008). We described the right protected by the Second Amendment as "'bearing arms for a lawful purpose'" and said that "the people [must] look for their protection against any violation by their fellowcitizens of the rights it recognizes" to the States' police power. 92 U.S., at 553. That discussion makes little sense if it is only a right to bear arms in a state militia.
Presser v. Illinois, 116 U.S. 252 (1886), held that the right to keep and bear arms was not violated by a law that forbade "bodies of men to associate together as military organizations, or to drill or parade with arms in cities and towns unless authorized by law." Id., at 264–265. This does not refute the individual-rights interpretation of the Amendment; no one supporting that interpretation has contended that States may not ban such groups. Justice Stevens [p. 621] presses Presser into service to support his view that the right to bear arms is limited to service in the militia by joining Presser's brief discussion of the Second Amendment with a later portion of the opinion making the seemingly relevant (to the Second Amendment) point that the plaintiff was not a member of the state militia. Unfortunately for Justice Stevens' argument, that later portion deals with the Fourteenth Amendment; it was the Fourteenth Amendment to which the plaintiff's nonmembership in the militia was relevant. Thus, Justice Stevens' statement that Presser "suggested that...nothing in the Constitution protected the use of arms outside the context of a militia," post, at 674-675, is simply wrong. Presser said nothing about the Second Amendment's meaning or scope, beyond the fact that it does not prevent the prohibition of private paramilitary organizations.
Justice Stevens places overwhelming reliance upon this Court's decision in Miller, 307 U.S. 174 (1939). "[H]undreds of judges," we are told, "have relied on the view of the amendment we endorsed there," post, at 638, and "[e]ven if the textual and historical arguments on both side of the issue were evenly balanced, respect for the well-settled views of all of our predecessors on this Court, and for the rule of law itself...would prevent most jurists from endorsing such a dramatic upheaval in the law," post, at 639. And what is, according to Justice Stevens, the holding of Miller that demands such obeisance? That the Second Amendment "protects the right to keep and bear arms for certain military purposes, but that it does not curtail the legislature's power to regulate the nonmilitary use and ownership of weapons." Post, at 637.
Nothing so clearly demonstrates the weakness of Justice Stevens' case. Miller did not hold that and cannot possibly be read to have held that. The judgment in the case upheld against a Second Amendment challenge two men's federal convictions for transporting an unregistered short-barreled [p. 622] shotgun in interstate commerce, in violation of the National Firearms Act, 48 Stat. 1236. It is entirely clear that the Court's basis for saying that the Second Amendment did not apply was not that the defendants were "bear[ing] arms" not "for...military purposes" but for "nonmilitary use," post, at 637. Rather, it was that the type of weapon at issue was not eligible for Second Amendment protection: "In the absence of any evidence tending to show that the possession or use of a [shortbarreled shotgun] at this time has some reasonable relationship to the preservation or efficiency of a well regulated militia, we cannot say that the Second Amendment guarantees the right to keep and bear such an instrument." 307 U.S., at 178 (emphasis added). "Certainly," the Court continued, "it is not within judicial notice that this weapon is any part of the ordinary military equipment or that its use could contribute to the common defense." Ibid. Beyond that, the opinion provided no explanation of the content of the right.
This holding is not only consistent with, but positively suggests, that the Second Amendment confers an individual right to keep and bear arms (though only arms that "have some reasonable relationship to the preservation or efficiency of a well regulated militia"). Had the Court believed that the Second Amendment protects only those serving in the militia, it would have been odd to examine the character of the weapon rather than simply note that the two crooks were not militiamen. Justice Stevens can say again and again that Miller did "not turn on the difference between muskets and sawed-off shotguns, it turned, rather, on the basic difference between the military and nonmilitary use and possession of guns," post, at 677, but the words of the opinion prove otherwise. The most Justice Stevens can plausibly claim for Miller is that it declined to decide the nature of the Second Amendment right, despite the Solicitor General's argument (made in the alternative) that the right was collective, see Brief for United States, O. T. 1938, [p. 623] No. 696, pp. 4–5. Miller stands only for the proposition that the Second Amendment right, whatever its nature, extends only to certain types of weapons.
It is particularly wrongheaded to read Miller for more than what it said, because the case did not even purport to be a thorough examination of the Second Amendment. Justice Stevens claims, post, at 676-677, that the opinion reached its conclusion "[a]fter reviewing many of the same sources that are discussed at greater length by the Court today." Not many, which was not entirely the Court's fault. The respondent made no appearance in the case, neither filing a brief nor appearing at oral argument; the Court heard from no one but the Government (reason enough, one would think, not to make that case the beginning and the end of this Court's consideration of the Second Amendment). See Frye, The Peculiar Story of United States v. Miller, 3 N. Y. U. J. L. & Liberty 48, 65–68 (2008). The Government's brief spent two pages discussing English legal sources, concluding "that at least the carrying of weapons without lawful occasion or excuse was always a crime" and that (because of the class-based restrictions and the prohibition on terrorizing people with dangerous or unusual weapons) "the early English law did not guarantee an unrestricted right to bear arms." Brief for United States, O. T. 1938, No. 696, at 9–11. It then went on to rely primarily on the discussion of the English right to bear arms in Aymette v. State, 21 Tenn. 154, for the proposition that the only uses of arms protected by the Second Amendment are those that relate to the militia, not self-defense. See Brief for United States, O. T. 1938, No. 696, at 12–18. The final section of the brief recognized that "some courts have said that the right to bear arms includes the right of the individual to have them for the protection of his person and property," and launched an alternative argument that "weapons which are commonly used by criminals," such as sawed-off shotguns, are not protected. See id., at 18–21. The Government's Miller brief thus provided [p. 624] scant discussion of the history of the Second Amendment—and the Court was presented with no counterdiscussion. As for the text of the Court's opinion itself, that discusses none of the history of the Second Amendment. It assumes from the prologue that the Amendment was designed to preserve the militia, 307 U.S., at 178 (which we do not dispute), and then reviews some historical materials dealing with the nature of the militia, and in particular with the nature of the arms their members were expected to possess, id., at 178–182. Not a word (not a word) about the history of the Second Amendment. This is the mighty rock upon which the dissent rests its case.
We may as well consider at this point (for we will have to consider eventually) what types of weapons Miller permits. Read in isolation, Miller's phrase "part of ordinary military equipment" could mean that only those weapons useful in warfare are protected. That would be a startling reading of the opinion, since it would mean that the National Firearms Act's restrictions on machineguns (not challenged in Miller) might be unconstitutional, machineguns being useful in warfare in 1939. We think that Miller's "ordinary military equipment" language must be read in tandem with what comes after: "[O]rdinarily when called for [militia] service [able-bodied] men were expected to appear bearing arms supplied by themselves and of the kind in common use at the time." 307 U.S., at 179. The traditional militia was formed from a pool of men bringing arms "in common use at the time" for lawful purposes like self-defense. "In the colonial [p. 625] and revolutionary war era, [small-arms] weapons used by militiamen and weapons used in defense of person and home were one and the same." State v. Kessler, 289 Ore. 359, 368, 614 P.2d 94, 98 (1980) (citing G. Neumann, Swords and Blades of the American Revolution 6–15, 252–254 (1973)). Indeed, that is precisely the way in which the Second Amendment's operative clause furthers the purpose announced in its preface. We therefore read Miller to say only that the Second Amendment does not protect those weapons not typically possessed by law-abiding citizens for lawful purposes, such as short-barreled shotguns. That accords with the historical understanding of the scope of the right, see Part III, infra.
We conclude that nothing in our precedents forecloses our adoption of the original understanding of the Second Amendment. It should be unsurprising that such a significant matter has been for so long judicially unresolved. For most of our history, the Bill of Rights was not thought applicable to the States, and the Federal Government did not significantly regulate the possession of firearms by law-abiding citizens. Other provisions of the Bill of Rights have similarly remained unilluminated for lengthy periods. This Court first [p. 626] held a law to violate the First Amendment's guarantee of freedom of speech in 1931, almost 150 years after the Amendment was ratified, see Near v. Minnesota ex rel. Olson, 283 U.S. 697 (1931), and it was not until after World War II that we held a law invalid under the Establishment Clause, see Illinois ex rel. McCollum v. Board of Ed. of School Dist. No. 71, Champaign Cty., 333 U.S. 203 (1948). Even a question as basic as the scope of proscribable libel was not addressed by this Court until 1964, nearly two centuries after the founding. See New York Times Co. v. Sullivan, 376 U. S. 254 (1964). It is demonstrably not true that, as Justice Stevens claims, post, at 676, "for most of our history, the invalidity of Second-Amendment-based objections to firearms regulations has been well settled and uncontroversial." For most of our history the question did not present itself.

#### III

Like most rights, the right secured by the Second Amendment is not unlimited. From Blackstone through the 19th-century cases, commentators and courts routinely explained that the right was not a right to keep and carry any weapon whatsoever in any manner whatsoever and for whatever purpose. See, e.g., Sheldon, in 5 Blume 346; Rawle 123; Pomeroy 152–153; Abbott 333. For example, the majority of the 19th-century courts to consider the question held that prohibitions on carrying concealed weapons were lawful under the Second Amendment or state analogues. See, e.g., State v. Chandler, 5 La. Ann., at 489–490; Nunn v. State, 1 Ga., at 251; see generally 2 Kent *340, n. 2; The American Students' Blackstone 84, n. 11 (G. Chase ed. 1884). Although we do not undertake an exhaustive historical analysis today of the full scope of the Second Amendment, nothing in our opinion should be taken to cast doubt on longstanding prohibitions on the possession of firearms by felons and the mentally ill, or laws forbidding the carrying of firearms in sensitive places such as schools and government buildings, or laws impos- [p. 627] ing conditions and qualifications on the commercial sale of arms.
We also recognize another important limitation on the right to keep and carry arms. Miller said, as we have explained, that the sorts of weapons protected were those "in common use at the time." 307 U.S., at 179. We think that limitation is fairly supported by the historical tradition of prohibiting the carrying of "dangerous and unusual weapons." See 4 Blackstone 148–149 (1769); 3 B. Wilson, Works of the Honourable James Wilson 79 (1804); J. Dunlap, The New-York Justice 8 (1815); C. Humphreys, A Compendium of the Common Law in Force in Kentucky 482 (1822); 1 W. Russell, A Treatise on Crimes and Indictable Misdemeanors 271–272 (1831); H. Stephen, Summary of the Criminal Law 48 (1840); E. Lewis, An Abridgment of the Criminal Law of the United States 64 (1847); F. Wharton, A Treatise on the Criminal Law of the United States 726 (1852). See also State v. Langford, 10 N.C. 381, 383–384 (1824); O'Neill v. State, 16 Ala. 65, 67 (1849); English v. State, 35 Tex. 473, 476 (1871); State v. Lanier, 71 N.C. 288, 289 (1874).
It may be objected that if weapons that are most useful in military service—M-16 rifles and the like—may be banned, then the Second Amendment right is completely detached from the prefatory clause. But as we have said, the conception of the militia at the time of the Second Amendment's ratification was the body of all citizens capable of military service, who would bring the sorts of lawful weapons that they possessed at home to militia duty. It may well be true today that a militia, to be as effective as militias in the 18th century, would require sophisticated arms that are highly unusual in society at large. Indeed, it may be true that no amount of small arms could be useful against modern-day bombers and tanks. But the fact that modern developments have limited the degree of fit between the prefatory clause [p. 628] and the protected right cannot change our interpretation of the right.

#### IV

We turn finally to the law at issue here. As we have said, the law totally bans handgun possession in the home. It also requires that any lawful firearm in the home be disassembled or bound by a trigger lock at all times, rendering it inoperable.
As the quotations earlier in this opinion demonstrate, the inherent right of self-defense has been central to the Second Amendment right. The handgun ban amounts to a prohibition of an entire class of "arms" that is overwhelmingly chosen by American society for that lawful purpose. The prohibition extends, moreover, to the home, where the need for defense of self, family, and property is most acute. Under any of the standards of scrutiny that we have applied to enumerated constitutional rights, banning from the home "the most preferred firearm in the nation to 'keep' and use for [p. 629] protection of one's home and family," 478 F.3d, at 400, would fail constitutional muster.
Few laws in the history of our Nation have come close to the severe restriction of the District's handgun ban. And some of those few have been struck down. In Nunn v. State, the Georgia Supreme Court struck down a prohibition on carrying pistols openly (even though it upheld a prohibition on carrying concealed weapons). See 1 Ga., at 251. In Andrews v. State, the Tennessee Supreme Court likewise held that a statute that forbade openly carrying a pistol "publicly or privately, without regard to time or place, or circumstances," 50 Tenn., at 187, violated the state constitutional provision (which the court equated with the Second Amendment). That was so even though the statute did not restrict the carrying of long guns. Ibid. See also State v. Reid, 1 Ala. 612, 616–617 (1840) ("A statute which, under the pretence of regulating, amounts to a destruction of the right, or which requires arms to be so borne as to render them wholly useless for the purpose of defence, would be clearly unconstitutional").
It is no answer to say, as petitioners do, that it is permissible to ban the possession of handguns so long as the possession of other firearms (i.e., long guns) is allowed. It is enough to note, as we have observed, that the American people have considered the handgun to be the quintessential self-defense weapon. There are many reasons that a citizen may prefer a handgun for home defense: It is easier to store in a location that is readily accessible in an emergency; it cannot easily be redirected or wrestled away by an attacker; it is easier to use for those without the upper-body strength to lift and aim a long gun; it can be pointed at a burglar with one hand while the other hand dials the police. Whatever the reason, handguns are the most popular weapon chosen by Americans for self-defense in the home, and a complete prohibition of their use is invalid.
[p. 630] We must also address the District's requirement (as applied to respondent's handgun) that firearms in the home be rendered and kept inoperable at all times. This makes it impossible for citizens to use them for the core lawful purpose of self-defense and is hence unconstitutional. The District argues that we should interpret this element of the statute to contain an exception for self-defense. See Brief for Petitioners 56–57. But we think that is precluded by the unequivocal text, and by the presence of certain other enumerated exceptions: "Except for law enforcement personnel..., each registrant shall keep any firearm in his possession unloaded and disassembled or bound by a trigger lock or similar device unless such firearm is kept at his place of business, or while being used for lawful recreational purposes within the District of Columbia." D. C. Code §7–2507.02. The nonexistence of a self-defense exception is also suggested by the D. C. Court of Appeals' statement that the statute forbids residents to use firearms to stop intruders, see McIntosh v. Washington, 395 A.2d 744, 755–756 (1978).
Apart from his challenge to the handgun ban and the trigger-lock requirement respondent asked the District Court to enjoin petitioners from enforcing the separate licensing requirement "in such a manner as to forbid the carrying of a firearm within one's home or possessed land without a license." App. 59a. The Court of Appeals did not invalidate the licensing requirement, but held only that the District "may not prevent [a handgun] from being moved throughout one's house." 478 F.3d, at 400. It then ordered the District Court to enter summary judgment "consistent [p. 631] with [respondent's] prayer for relief." Id., at 401. Before this Court petitioners have stated that "if the handgun ban is struck down and respondent registers a handgun, he could obtain a license, assuming he is not otherwise disqualified," by which they apparently mean if he is not a felon and is not insane. Brief for Petitioners 58. Respondent conceded at oral argument that he does not "have a problem with...licensing" and that the District's law is permissible so long as it is "not enforced in an arbitrary and capricious manner." Tr. of Oral Arg. 74–75. We therefore assume that petitioners' issuance of a license will satisfy respondent's prayer for relief and do not address the licensing requirement.
Justice Breyer has devoted most of his separate dissent to the handgun ban. He says that, even assuming the Second Amendment is a personal guarantee of the right to bear arms, the District's prohibition is valid. He first tries to establish this by founding-era historical precedent, pointing to various restrictive laws in the colonial period. These demonstrate, in his view, that the District's law "imposes a burden upon gun owners that seems proportionately no greater than restrictions in existence at the time the Second Amendment was adopted." Post, at 682. Of the laws he cites, only one offers even marginal support for his assertion. A 1783 Massachusetts law forbade the residents of Boston to "take into" or "receive into" "any Dwelling House, Stable, Barn, Out-house, Ware-house, Store, Shop or other Building" loaded firearms, and permitted the seizure of any loaded firearms that "shall be found" there. Act of Mar. 1, 1783, ch. 13, 1783 Mass. Acts p. 218. That statute's text and its prologue, which makes clear that the purpose of the prohibition was to eliminate the danger to firefighters posed by the "depositing of loaded Arms" in buildings, give reason to doubt that colonial Boston authorities would have enforced that general prohibition against someone who temporarily loaded a firearm to confront an intruder (despite the law's [p. 632] application in that case). In any case, we would not stake our interpretation of the Second Amendment upon a single law, in effect in a single city, that contradicts the overwhelming weight of other evidence regarding the right to keep and bear arms for defense of the home. The other laws Justice Breyer cites are gunpowder-storage laws that he concedes did not clearly prohibit loaded weapons, but required only that excess gunpowder be kept in a special container or on the top floor of the home. Post, at 686. Nothing about those fire-safety laws undermines our analysis; they do not remotely burden the right of self-defense as much as an absolute ban on handguns. Nor, correspondingly, does our analysis suggest the invalidity of laws regulating the storage of firearms to prevent accidents.
Justice Breyer points to other founding-era laws that he says "restricted the firing of guns within the city limits to at least some degree" in Boston, Philadelphia and New York. Post, at 683 (citing Churchill, Gun Regulation, the Police Power, and the Right to Keep Arms in Early America, 25 Law & Hist. Rev. 139, 162 (2007)). Those laws provide no support for the severe restriction in the present case. The New York law levied a fine of 20 shillings on anyone who fired a gun in certain places (including houses) on New Year's Eve and the first two days of January, and was aimed at preventing the "great Damages...frequently done on [those days] by persons going House to House, with Guns and other Firearms and being often intoxicated with Liquor." 5 Colonial Laws of New York 244–246 (1894). It is inconceivable that this law would have been enforced against a person exercising his right to self-defense on New Year's Day against such drunken hooligans. The Pennsylvania law to which Justice Breyer refers levied a fine of 5 shillings on one who fired a gun or set off fireworks in Philadelphia without first obtaining a license from the governor. See Act of Aug. 26, 1721, §4, in 3 Stat. at Large 253–254. Given Justice Wilson's explanation [p. 633] that the right to self-defense with arms was protected by the Pennsylvania Constitution, it is unlikely that this law (which in any event amounted to at most a licensing regime) would have been enforced against a person who used firearms for self-defense. Justice Breyer cites a Rhode Island law that simply levied a 5-shilling fine on those who fired guns in streets and taverns, a law obviously inapplicable to this case. See An Act for preventing Mischief being done in the town of Newport, or in any other town in this Government, 1731, Rhode Island Session Laws. Finally, Justice Breyer points to a Massachusetts law similar to the Pennsylvania law, prohibiting "discharg[ing] any Gun or Pistol charged with Shot or Ball in the Town of Boston." Act of May 28, 1746, ch. X, Acts and Laws of Mass. Bay 208. It is again implausible that this would have been enforced against a citizen acting in self-defense, particularly given its preambulatory reference to "the indiscreet firing of Guns." Ibid. (preamble) (emphasis added).
A broader point about the laws that Justice Breyer cites: All of them punished the discharge (or loading) of guns with a small fine and forfeiture of the weapon (or in a few cases a very brief stay in the local jail), not with significant criminal penalties. They are akin to modern penalties for minor public-safety infractions like speeding or jaywalking. And although such public-safety laws may not contain exceptions for self-defense, it is inconceivable that the threat of a jaywalking ticket would deter someone from disregarding a "Do Not Walk" sign in order to flee an attacker, or that the Government would enforce those laws under such circumstances. Likewise, we do not think that a law imposing a [p. 634] 5-shilling fine and forfeiture of the gun would have prevented a person in the founding era from using a gun to protect himself or his family from violence, or that if he did so the law would be enforced against him. The District law, by contrast, far from imposing a minor fine, threatens citizens with a year in prison (five years for a second violation) for even obtaining a gun in the first place. See D. C. Code §7–2507.06.
Justice Breyer moves on to make a broad jurisprudential point: He criticizes us for declining to establish a level of scrutiny for evaluating Second Amendment restrictions. He proposes, explicitly at least, none of the traditionally expressed levels (strict scrutiny, intermediate scrutiny, rational basis), but rather a judge-empowering "interest balancing inquiry" that "asks whether the statute burdens a protected interest in a way or to an extent that is out of proportion to the statute's salutary effects upon other important governmental interests." Post, at 689-690. After an exhaustive discussion of the arguments for and against gun control, Justice Breyer arrives at his interest balanced answer: because handgun violence is a problem, because the law is limited to an urban area, and because there were somewhat similar restrictions in the founding period (a false proposition that we have already discussed), the interest-balancing inquiry results in the constitutionality of the handgun ban. QED.
We know of no other enumerated constitutional right whose core protection has been subjected to a freestanding "interest-balancing" approach. The very enumeration of the right takes out of the hands of government—even the Third Branch of Government—the power to decide on a case-by-case basis whether the right is really worth insisting upon. A constitutional guarantee subject to future judges' assessments of its usefulness is no constitutional guarantee at all. Constitutional rights are enshrined with the scope they were understood to have when the people adopted [p. 635] them, whether or not future legislatures or (yes) even future judges think that scope too broad. We would not apply an "interest-balancing" approach to the prohibition of a peaceful neo-Nazi march through Skokie. See National Socialist Party of America v. Skokie, 432 U.S. 43 (1977) (per curiam). The First Amendment contains the freedom-of-speech guarantee that the people ratified, which included exceptions for obscenity, libel, and disclosure of state secrets, but not for the expression of extremely unpopular and wrong-headed views. The Second Amendment is no different. Like the First, it is the very product of an interest-balancing by the people—which Justice Breyer would now conduct for them anew. And whatever else it leaves to future evaluation, it surely elevates above all other interests the right of law-abiding, responsible citizens to use arms in defense of hearth and home.
Justice Breyer chides us for leaving so many applications of the right to keep and bear arms in doubt, and for not providing extensive historical justification for those regulations of the right that we describe as permissible. See post, at 720-721. But since this case represents this Court's first in-depth examination of the Second Amendment, one should not expect it to clarify the entire field, any more than Reynolds v. United States, 98 U. S. 145 (1879), our first in-depth Free Exercise Clause case, left that area in a state of utter certainty. And there will be time enough to expound upon the historical justifications for the exceptions we have mentioned if and when those exceptions come before us.
In sum, we hold that the District's ban on handgun possession in the home violates the Second Amendment, as does its prohibition against rendering any lawful firearm in the home operable for the purpose of immediate self-defense. Assuming that Heller is not disqualified from the exercise of Second Amendment rights, the District must permit him to register his handgun and must issue him a license to carry it in the home. [p. 636]
We are aware of the problem of handgun violence in this country, and we take seriously the concerns raised by the many amici who believe that prohibition of handgun ownership is a solution. The Constitution leaves the District of Columbia a variety of tools for combating that problem, including some measures regulating handguns, see supra, at 626-627, and n. 26. But the enshrinement of constitutional rights necessarily takes certain policy choices off the table. These include the absolute prohibition of handguns held and used for self-defense in the home. Undoubtedly some think that the Second Amendment is outmoded in a society where our standing army is the pride of our Nation, where well-trained police forces provide personal security, and where gun violence is a serious problem. That is perhaps debatable, but what is not debatable is that it is not the role of this Court to pronounce the Second Amendment extinct.
We affirm the judgment of the Court of Appeals.
It is so ordered.

## Notes

* ↑ . There are minor exceptions to all of these prohibitions, none of which is relevant here.
* ↑ . That construction has not been challenged here.
* ↑ . As Sutherland explains, the key 18th-century English case on the effect of preambles, Copeman v. Gallant, 1 P. Wms. 314, 24 Eng. Rep. 404 (1716), stated that "the preamble could not be used to restrict the effect of the words of the purview." J. Sutherland, Statutes and Statutory Construction, 47.04 (N. Singer ed. 5th ed. 1992). This rule was modified in England in an 1826 case to give more importance to the preamble, but in America "the settled principle of law is that the preamble cannot control the enacting part of the statute in cases where the enacting part is expressed in clear, unambiguous terms." Ibid.
* ↑ . Justice Stevens criticizes us for discussing the prologue last. Ibid. But if a prologue can be used only to clarify an ambiguous operative provi­sion, surely the first step must be to determine whether the operative provision is ambiguous. It might be argued, we suppose, that the prologue itself should be one of the factors that go into the determination of whether the operative provision is ambiguous—but that would cause the prologue to be used to produce ambiguity rather than just to resolve it. In any event, even if we considered the prologue along with the operative provision we would reach the same result we do today, since (as we explain) our interpretation of "the right of the people to keep and bear arms" furthers the purpose of an effective militia no less than (indeed, more than) the dissent's interpretation. See infra, at 599-600.
* ↑ . Justice Stevens is of course correct, post, at 645, that the right to assemble cannot be exercised alone, but it is still an individual right, and not one conditioned upon membership in some defined "assembly," as he contends the right to bear arms is conditioned upon membership in a defined militia. And Justice Stevens is dead wrong to think that the right to petition is "primarily collective in nature." Ibid. See McDonald v. Smith, 472 U.S. 479, 482–484 (1985) (describing historical origins of right to petition).
* ↑ . If we look to other founding-era documents, we find that some state constitutions used the term "the people" to refer to the people collectively, in contrast to "citizen," which was used to invoke individual rights. See Heyman, Natural Rights and the Second Amendment, in The Second Amendment in Law and History 179, 193–195 (C. Bogus ed. 2000) (hereinafter Bogus). But that usage was not remotely uniform. See, e.g., N. C. Declaration of Rights §XIV (1776), in 5 The Federal and State Constitutions, Colonial Charters, and Other Organic Laws 2787, 2788 (F. Thorpe ed. 1909) (hereinafter Thorpe) (jury trial); Md. Declaration of Rights §XVIII (1776), in 3 id., at 1686, 1688 (vicinage requirement); Vt. Declaration of Rights ch. 1, §XI (1777), in 6 id., at 3737, 3741 (searches and seizures); Pa. Declaration of Rights §XII (1776), in 5 id., at 3081, 3083 (free speech). And, most importantly, it was clearly not the terminology used in the Federal Constitution, given the First, Fourth, and Ninth Amendments.

* ↑ . Justice Stevens contends, post, at 650, that since we assert that adding "against" to "bear arms" gives it a military meaning we must concede that adding a purposive qualifying phrase to "bear arms" can alter its meaning. But the difference is that we do not maintain that "against" alters the meaning of "bear arms" but merely that it clarifies which of various meanings (one of which is military) is intended. Justice Stevens, however, argues that "[t]he term 'bear arms' is a familiar idiom; when used unadorned by any additional words, its meaning is 'to serve as a soldier, do military service, fight.'" Post, at 646. He therefore must establish that adding a contradictory purposive phrase can alter a word's meaning.
* ↑ . Justice Stevens finds support for his legislative history inference from the recorded views of one Antifederalist member of the House. Post, at 26 n. 25. "The claim that the best or most representative reading of the [language of the] amendments would conform to the understanding and concerns of [the Antifederalists] is...highly problematic." Rakove, The Second Amendment: The Highest Stage of Originalism, Bogus 74, 81.
* ↑ . The same applies to the conscientious-objector amendments proposed by Virginia and North Carolina, which said: "That any person religiously scrupulous of bearing arms ought to be exempted upon payment of an equivalent to employ another to bear arms in his stead." See Veit 19; 4 J. Eliot, The Debates in the Several State Constitutions on the Adoption of the Federal Constitution 243, 244 (2d ed. 1836) (reprinted 1941). Certainly their second use of the phrase ("bear arms in his stead") refers, by reason of context, to compulsory bearing of arms for military duty. But their first use of the phrase ("any person religiously scrupulous of bearing arms") assuredly did not refer to people whose God allowed them to bear arms for defense of themselves but not for defense of their country.
* ↑ . Faced with this clear historical usage, Justice Stevens resorts to the bizarre argument that because the word "to" is not included before "bear" (whereas it is included before "petition" in the First Amendment), the unitary meaning of "to keep and bear" is established. Post, at 651, n. 13. We have never heard of the proposition that omitting repetition of the "to" causes two verbs with different meanings to become one. A promise "to support and to defend the Constitution of the United States" is not a whit different from a promise "to support and defend the Constitution of the United States."
* ↑ . Cf. 3 Geo., 34, §3, in 7 Eng. Stat. at Large 126 (1748) ("That the Prohibition contained...in this Act, of having, keeping, bearing, or wearing any Arms or Warlike Weapons...shall not extend...to any Officers or their Assistants, employed in the Execution of Justice...").
* ↑ . Contrary to Justice Stevens' wholly unsupported assertion, post, at 636, 652, there was no pre-existing right in English law "to use weapons for certain military purposes" or to use arms in an organized militia.
* ↑ . Article I, §8, cl. 16 of the Constitution gives Congress the power
* ↑ . Justice Stevens says that the drafters of the Virginia Declaration of Rights rejected this proposal and adopted "instead" a provision written by George Mason stressing the importance of the militia. See post, at 659, and n. 24. There is no evidence that the drafters regarded the Mason proposal as a substitute for the Jefferson proposal.
* ↑ . Justice Stevens quotes some of Tucker's unpublished notes, which he claims show that Tucker had ambiguous views about the Second Amendment. See post, at 666, and n. 32. But it is clear from the notes that Tucker located the power of States to arm their militias in the Tenth Amendment, and that he cited the Second Amendment for the proposition that such armament could not run afoul of any power of the federal government (since the amendment prohibits Congress from ordering disarmament). Nothing in the passage implies that the Second Amendment pertains only to the carrying of arms in the organized militia.
* ↑ . Rawle, writing before our decision in Barron ex rel. Tiernan v. Mayor of Baltimore, 7 Pet. 243 (1833), believed that the Second Amendment could be applied against the States. Such a belief would of course be nonsensical on petitioners' view that it protected only a right to possess and carry arms when conscripted by the State itself into militia service.
* ↑ . Justice Stevens suggests that this is not obvious because free blacks in Virginia had been required to muster without arms. See post, at 663, n. 29 (citing Siegel, The Federal Government's Power to Enact Color-Conscious Laws, 92 Nw. U. L. Rev. 477, 497 (1998)). But that could not have been the type of law referred to in Aldridge, because that practice had stopped 30 years earlier when blacks were excluded entirely from the militia by the First Militia Act. See Siegel, supra, at 498, n. 120. Justice Stevens further suggests that laws barring blacks from militia service could have been said to violate the "right to bear arms." But under Justice Stevens' reading of the Second Amendment (we think), the protected right is the right to carry arms to the extent one is enrolled in the militia, not the right to be in the militia. Perhaps Justice Stevens really does adopt the full-blown idiomatic meaning of "bear arms," in which case every man and woman in this country has a right "to be a soldier" or even "to wage war." In any case, it is clear to us that Aldridge's allusion to the existing Virginia "restriction" upon the right of free blacks "to bear arms" could only have referred to "laws prohibiting blacks from keeping weapons," Siegel, supra, at 497–498.
* ↑ . Justice Stevens' accusation that this is "not accurate," post, at 673, is wrong. It is true it was the indictment that described the right as "bearing arms for a lawful purpose." But, in explicit reference to the right described in the indictment, the Court stated that "The second amendment declares that it [i.e., the right of bearing arms for a lawful purpose] shall not be infringed." 92 U.S., at 553.
* ↑ . With respect to Cruikshank's continuing validity on incorporation, a question not presented by this case, we note that Cruikshank also said that the First Amendment did not apply against the States and did not engage in the sort of Fourteenth Amendment inquiry required by our later cases. Our later decisions in Presser v. Illinois, 116 U.S. 252, 265 (1886) and Miller v. Texas, 153 U.S. 535, 538 (1894), reaffirmed that the Second Amendment applies only to the Federal Government.
* ↑ . As for the "hundreds of judges," post, at 638, who have relied on the view of the Second Amendment Justice Stevens claims we endorsed in Miller: If so, they overread Miller. And their erroneous reliance upon an uncontested and virtually unreasoned case cannot nullify the reliance of millions of Americans (as our historical analysis has shown) upon the true meaning of the right to keep and bear arms. In any event, it should not be thought that the cases decided by these judges would necessarily have come out differently under a proper interpretation of the right.
* ↑ . Miller was briefly mentioned in our decision in Lewis v. United States, 445 U.S. 55 (1980), an appeal from a conviction for being a felon in possession of a firearm. The challenge was based on the contention that the prior felony conviction had been unconstitutional. No Second Amendment claim was raised or briefed by any party. In the course of rejecting the asserted challenge, the Court commented gratuitously, in a footnote, that "[t]hese legislative restrictions on the use of firearms are neither based upon constitutionally suspect criteria, nor do they trench upon any constitutionally protected liberties. See United States v. Miller...(the Second Amendment guarantees no right to keep and bear a firearm that does not have 'some reasonable relationship to the preservation or efficiency of a well regulated militia')." Id., at 65–66, n. 8. The footnote then cites several Court of Appeals cases to the same effect. It is inconceivable that we would rest our interpretation of the basic meaning of any guarantee of the Bill of Rights upon such a footnoted dictum in a case where the point was not at issue and was not argued.
* ↑ . We identify these presumptively lawful regulatory measures only as examples; our list does not purport to be exhaustive.
* ↑ . Justice Breyer correctly notes that this law, like almost all laws, would pass rational-basis scrutiny. Post, at 667-668. But rational-basis scrutiny is a mode of analysis we have used when evaluating laws under constitutional commands that are themselves prohibitions on irrational laws. See, e.g., Engquist v. Oregon Dept. of Agriculture, 553 U.S. 591, 602 (2008) . In those cases, "rational basis" is not just the standard of scrutiny, but the very substance of the constitutional guarantee. Obviously, the same test could not be used to evaluate the extent to which a legislature may regulate a specific, enumerated right, be it the freedom of speech, the guarantee against double jeopardy, the right to counsel, or the right to keep and bear arms. See United States v. Carolene Products Co., 304 U.S. 144, 152, n. 4 (1938) ("There may be narrower scope for operation of the presumption of constitutionality [i.e., narrower than that provided by rational-basis review] when legislation appears on its face to be within a specific prohibition of the Constitution, such as those of the first ten amendments..."). If all that was required to overcome the right to keep and bear arms was a rational basis, the Second Amendment would be redundant with the separate constitutional prohibitions on irrational laws, and would have no effect.
* ↑ . McIntosh upheld the law against a claim that it violated the Equal Protection Clause by arbitrarily distinguishing between residences and businesses. See 395 A.2d, at 755. One of the rational bases listed for that distinction was the legislative finding "that for each intruder stopped by a firearm there are four gun-related accidents within the home." Ibid. That tradeoff would not bear mention if the statute did not prevent stopping intruders by firearms.
* ↑ . The Supreme Court of Pennsylvania described the amount of five shillings in a contract matter in 1792 as "nominal consideration." Morris's Lessee v. Smith, 4 Dall. 119, 120 (Pa. 1792). Many of the laws cited punished violation with fine in a similar amount; the 1783 Massachusetts gunpowder-storage law carried a somewhat larger fine of £10 (200 shillings) and forfeiture of the weapon.
