# Alien and Sedition Acts

The Alien and Sedition Acts were a set of four laws enacted in 1798 that applied restrictions to immigration and speech in the United States. The Naturalization Act of 1798 increased the requirements to seek citizenship, the Alien Friends Act of 1798 allowed the president to imprison and deport non-citizens, the Alien Enemies Act of 1798 gave the president additional powers to detain non-citizens during times of war, invasion, or predatory incursion, and the Sedition Act of 1798 criminalized false and malicious statements about the federal government. The Alien Friends Act and the Sedition Act expired in 1800, and the Naturalization Act was repealed in 1802. The Alien Enemies Act, as amended, is still in effect as 50 U.S.C. ch. 3.
The Alien and Sedition Acts were passed by a Congress controlled by the Federalist Party, directed against the Democratic-Republicans, the party typically favored by new citizens. Only Democratic-Republican journalists were prosecuted by these laws. Publicity from Sedition Act trials caused massive criticism and contributed to the Federalists being removed from power in the 1800 election.
The acts were supported by the Federalist Party, and supporters argued that the bills strengthened national security during the Quasi-War, an undeclared naval war with France from 1798 to 1800. The acts were denounced by Democratic-Republicans as suppression of voters and violation of free speech under the First Amendment. While they were in effect, the Alien and Sedition Acts, and the Sedition Act in particular, were used to suppress publishers affiliated with the Democratic-Republicans, and several publishers were arrested for criticism of the Adams administration. The Democratic-Republicans took power in 1800 because of backlash to the Alien and Sedition Acts, and all but the Alien Enemies Act were eliminated by the next Congress. The Alien Enemies Act has been invoked several times since, particularly during World War II by President Roosevelt. These laws were used to imprison over tens of thousands of noncitizens of German, Italian, and Japanese descent, all known as "Enemy Aliens."
The Alien and Sedition Acts are generally received negatively by modern historians. The U.S. Supreme Court beginning in the mid-20th century has indicated that aspects of the laws would likely be found unconstitutional.
The Alien Enemies Act was mentioned by President Donald Trump during a campaign rally held at Madison Square Garden for the 2024 presidential election, claiming that he would use them to remove illegal immigrants operating within gangs and criminal networks on "day one" if he were to win the presidency by invoking the acts. After being sworn in as President on January 20, 2025, he mentioned it again during his inaugural address.
On March 15, 2025, Trump invoked the Alien Enemies Act to authorize the deportation of Venezuelan suspected gang members to the Terrorism Confinement Center (CECOT) in El Salvador. Trump's executive order was temporarily blocked the same day by Judge James Boasberg, following a lawsuit seeking to stop the deportations.

## History

The Alien and Sedition Acts were passed by Congress while it was controlled by the Federalist Party in 1798. Members of the Federalist Party grew increasingly distrustful of the opposing Democratic-Republican Party with the latter's support of France in the midst of the French Revolution. Some appeared to desire a similar revolution in the United States to overthrow the government and social structure. Newspapers sympathizing with each side exacerbated the tensions by accusing the other side's leaders of corruption, incompetence, and treason. The spreading unrest in Europe and calls for secession in the United States appeared to threaten the newly formed American republic. Some of this agitation was seen by Federalists as having been caused by French and French-sympathizing immigrants. The Alien and Sedition Acts were opposed for different reasons, including the prevention of potential unrest by targeting immigrants, restriction of speech that may induce crime, reduction of partisan divides by penalizing expressly partisan speech, and suppression of political opponents of the Federalists.
The acts were highly controversial at the time, especially the Sedition Act. The Sedition Act, which was signed into law by Adams on July 14, 1798, was hotly debated in the Federalist-controlled Congress and passed only after multiple amendments softening its terms, such as enabling defendants to argue in their defense that their statements had been true. Still, it passed the House only after three votes and another amendment causing it to automatically expire in March 1801. They continued to be loudly protested and were a major political issue in the election of 1800. Opposition to them resulted in the also-controversial Virginia and Kentucky Resolutions, authored by James Madison and Thomas Jefferson. Upon assuming the presidency, Jefferson pardoned those still serving sentences under the Sedition Act,$^{:231}$ and Congress soon repaid their fines.

## Acts
### Alien Friends Act

The Alien Friends Act (officially "An Act Concerning Aliens") authorized the president to arbitrarily deport any non-citizen that was determined to be "dangerous to the peace and safety of the United States." Once a non-citizen was determined to be dangerous, or was suspected of conspiring against the government, the president had the power to set a reasonable amount of time for departure, and remaining after the time limit could result to up to three years in prison. The law was never directly enforced, but it was often used in conjunction with the Sedition Act to suppress criticism of the Adams administration. Upon enactment, the Alien Friends Act was authorized for two years, and it was allowed to expire at the end of this period. Democratic-Republicans opposed the law, with Thomas Jefferson referring to it as "a most detestable thing... worthy of the 8th or 9th century."$^{:249}$
While the law was not directly enforced, it resulted in the voluntary departure of foreigners who feared that they would be charged under the act. The Adams administration encouraged these departures, and Secretary of State Timothy Pickering would ensure that the ships were granted passage. Though Adams did not delegate the final decision-making power, Secretary Pickering was responsible for overseeing enforcement of the Alien Friends Act. Both Adams and Pickering considered the law too weak to be effective; Pickering expressed his desire for the law to require sureties and authorize detainment prior to deportation.
Many French nationals were considered for deportation but were allowed to leave willingly, or Adams declined to take action against them. These figures included: philosopher Constantin François de Chassebœuf, comte de Volney, General Victor Collot, scholar Médéric Louis Élie Moreau de Saint-Méry, diplomat Victor Marie du Pont, journalist William Duane, scientist Joseph Priestley, and journalist William Cobbett. Secretary Pickering also proposed applying the act against the French diplomatic delegation to the United States, but Adams refused. Journalist John Daly Burk agreed to leave under the act informally to avoid being tried for sedition, but he went into hiding in Virginia until the act's expiration.

### Alien Enemies Act

The Alien Enemies Act (officially "An Act Respecting Alien Enemies") was passed to supplement the Alien Friends Act, granting the government additional powers to regulate non-citizens that would take effect in times of war. Under this law, the president could authorize the arrest, relocation, or deportation of any male over the age of 14 who hailed from a foreign enemy country. It also provided some legal protections for those subject to the law. Unlike the other acts, this act was largely unopposed by the Democratic-Republicans.$^{:249}$
The Alien Enemies Act was not allowed to expire with the other Alien and Sedition Acts, and it remains in effect as Chapter 3, Sections 21–24 of Title 50 of the United States Code. President James Madison invoked the act against British nationals during the War of 1812. President Woodrow Wilson invoked the act against nationals of the Central Powers during World War I. In 1918, an amendment to the act struck the provision restricting the law to males.
On December 7, 1941, in response to the bombing of Pearl Harbor, President Franklin D. Roosevelt used the authority of the revised Alien Enemies Act to issue presidential proclamations #2525 (Alien Enemies – Japanese), #2526 (Alien Enemies – German), and #2527 (Alien Enemies – Italian), to apprehend, restrain, secure, and remove Japanese, German, and Italian non-citizens. Roosevelt later cited further wartime powers to issue Executive Order 9066, which interned Japanese Americans using powers unrelated to the Alien Enemies Act. Hostilities with Germany and Italy ended in May 1945, and President Harry S. Truman issued presidential proclamation #2655 on July 14. The proclamation gave the attorney general authority regarding enemy aliens within the continental United States, to decide whether they are "dangerous to the public peace and safety of the United States," to order them removed, and to create regulations governing their removal, citing the Alien Enemies Act. On September 8, 1945, Truman issued presidential proclamation #2662, which authorized the secretary of state to remove enemy aliens that had been sent to the United States from Latin American countries. On April 10, 1946, Truman issued presidential proclamation #2685, which modified the previous proclamation, and set a 30-day deadline for removal.
In Ludecke v. Watkins (1948), the Supreme Court interpreted the time of release under the Alien Enemies Act. German alien Kurt G. W. Lüdecke was detained on December 8, 1941, under Proclamation 2526, and continued to be held after cessation of hostilities. In 1947, Lüdecke petitioned for a writ of habeas corpus to order his release, after the attorney general ordered him deported. The court ruled 5–4 to affirm the district court and appellate decisions to deny the writ of habeas corpus. The Court also concluded that the Alien Enemies Act allowed for detainment beyond the time hostilities ceased until an actual treaty was signed with the hostile nation or government or the until the president determines that hostilities have concluded.
On September 20, 2024, then-nominee Donald Trump announced that if elected president for a second term he would invoke the Alien Enemies Act of 1798 to expedite the removal of non-citizens and criminal networks operating in the United States. In his second inaugural address on January 20, 2025, Trump again stated that he would invoke the Alien Enemies Act.
On March 15, 2025, Trump invoked the Alien Enemies Act of 1798 against what he termed an invasion being perpetrated or attempted by Tren de Aragua. At 7:26 p.m. that day, U.S. district judge James E. Boasberg formally posted his written order to block this policy for up to two weeks, pending a hearing scheduled for March 21. However, a number of planes had already taken off and continued flying to their destination because the blocking order was formally filed too late. Boasberg held a fact-finding hearing on March 17 regarding the government's compliance. The government refused to provide the requested information at that hearing and it similarly disregarded the judge's extended deadline of noon the next day, arguing that Judge Boasberg was demanding information irrelevant to the case. White House deputy press secretary Harrison Fields bragged that "this judge was too slow. We played a little game of 'catch me if you can,' and guess what, the judge wasn’t able to catch us on this one." Meanwhile, Trump posted to social media that Boasberg was an "activist judge" acting outside his purview and "should be IMPEACHED!!!" In response, Chief Justice of the United States John Roberts issued a statement that, when someone disagrees with a judge's decision, the "appropriate response" is to appeal the decision, not to impeach the judge.

### Naturalization Act

The Naturalization Act increased the residency requirement for American citizenship from five to 14 years and increased the notice time from three to five years. Although the law was passed under the guise of protecting national security, most historians conclude it was really intended to decrease the number of citizens, and thus voters, who disagreed with the Federalist Party. At the time, the majority of immigrants supported Thomas Jefferson and the Democratic-Republicans—the political opponents of the Federalists. It did not have an expiration date, but it was repealed by the Naturalization Law of 1802.

### Sedition Act

The Federalist-controlled Congress passed the Sedition Act by a vote of 44 to 41. The Sedition Act made it illegal to make false or malicious statements about the federal government. The act was used to suppress speech critical of the Adams administration, including the prosecution and conviction of many Jeffersonian newspaper owners who disagreed with the Federalist Party. The Sedition Act did not extend enforcement to speech about the Vice President, as then-incumbent Thomas Jefferson was a political opponent of the Federalist-controlled Congress. The Sedition Act was allowed to expire in 1800, and its enactment is credited with helping Jefferson win the presidential election that year.
Prominent prosecutions under the Sedition Act included:
* James T. Callender, a Scottish pamphleteer who had fled to the United States after becoming embroiled in controversy due to his political opinions again British imperialism. Living first in Philadelphia, then seeking refuge close by in Virginia, he wrote a book titled The Prospect Before Us (read and approved by Vice President Jefferson before publication), in which he called the Adams administration a "continual tempest of malignant passions," and referred to the President as a "repulsive pedant, a gross hypocrite, and an unprincipled oppressor." Callender, already residing in Virginia and writing for the Richmond Examiner, was indicted in mid-1800 under the Sedition Act, and was subsequently convicted, fined $200, and sentenced to nine months in jail.$^{:211–220}$
* Matthew Lyon was a Democratic-Republican congressman from Vermont. He was the first individual to be placed on trial under the Alien and Sedition Acts. He was indicted in 1800 for an essay he had written in the Vermont Journal, where he had accused the administration of "ridiculous pomp, foolish adulation, and selfish avarice." While awaiting trial, Lyon commenced publication of Lyon's Republican Magazine, subtitled "The Scourge of Aristocracy." At trial, he was fined $1,000, and sentenced to four months in jail. After his release, he returned to Congress.$^{:102–108}$
* Benjamin Franklin Bache was the editor of the Philadelphia Aurora, a Democratic-Republican newspaper. Bache had accused George Washington of incompetence and financial irregularities, and "the blind, bald, crippled, toothless, querulous Adams" of nepotism and monarchical ambition. He was arrested in 1798 under the Sedition Act, but he died of yellow fever before trial.$^{:27–29,65,96}$
* Anthony Haswell was an English immigrant, and a printer of the Jeffersonian Vermont Gazette. Sourced from the Philadelphia Aurora, Haswell had reprinted Bache's claim that the federal government employed Tories. Haswell also published an advertisement from Lyon's sons for a lottery to raise money for his fine that decried Lyon's oppression by jailers exercising "usurped powers". Haswell was found guilty of seditious libel by judge William Paterson, and sentenced to a two-month imprisonment and a $200 fine.
* Luther Baldwin was indicted, convicted, and fined $100 for a drunken incident that occurred during a visit by President Adams to Newark, New Jersey. Upon hearing a gun report during a parade, he yelled "I hope it hit Adams in the [backside]."$^{:112–14}$
* In November 1798, David Brown led a group in Dedham, Massachusetts, including Benjamin Fairbanks, in setting up a liberty pole with the words, "No Stamp Act, No Sedition Act, No Alien Bills, No Land Tax, downfall to the Tyrants of America; peace and retirement to the President; Long Live the Vice President." Brown was arrested in Andover, Massachusetts, but because he could not afford the $4,000 bail, he was taken to Salem for trial. Brown was tried in June 1799. Brown pleaded guilty, but Justice Samuel Chase asked him to name others who had assisted him. Brown refused, was fined $480 (equivalent to $8,900 in 2024), and sentenced to eighteen months in prison, the most severe sentence imposed under the Sedition Act.

## Reaction

After the passage of the highly unpopular Alien and Sedition Acts, protests occurred across the country, with some of the largest being seen in Kentucky, where the crowds were so large they filled the streets and the entire town square of Lexington. Critics argued that they were primarily an attempt to suppress voters who disagreed with the Federalist party and its teachings, and violated the right of freedom of speech in the First Amendment to the U.S. Constitution. They also raised concerns that the Alien and Sedition acts gave disproportionate power to the federal executive compared to state governments and other branches of the federal government. Noting the outrage among the populace, the Democratic-Republicans made the Alien and Sedition Acts an important issue in the 1800 presidential election campaign. While government authorities prepared lists of aliens for deportation, many aliens fled the country during the debate over the Alien and Sedition Acts, and Adams never signed a deportation order.$^{:187–193}$
The Virginia and Kentucky state legislatures also passed the Kentucky and Virginia Resolutions, secretly authored by Thomas Jefferson and James Madison, denouncing the federal legislation. While the eventual resolutions followed Madison in advocating "interposition", Jefferson's initial draft would have nullified the acts and even threatened secession. Jefferson's biographer Dumas Malone argued that this might have gotten Jefferson impeached for treason, had his actions become known at the time. In writing the Kentucky Resolutions, Jefferson warned that, "unless arrested at the threshold", the Alien and Sedition Acts would "necessarily drive these states into revolution and blood".
The Alien and Sedition Acts were never appealed to the Supreme Court, whose power of judicial review was not established until Marbury v. Madison in 1803. Subsequent mentions in Supreme Court opinions beginning in the mid-20th century have assumed that the Sedition Act would today be found unconstitutional. Most modern historians view the Alien and Sedition Acts in a negative light, considering them to have been a mistake.
