List of U.S. states by date of admission to the Union - wikipedia List of U.S. states by date of admission to the Union Map of the United States with names and borders of states The order in which the original 13 states ratified the 1787 Constitution, then the order in which the others were admitted to the union A state of the United States of America is one of the 50 constituent entities that shares its sovereignty with the federal government. Americans are citizens of both the federal republic and of the state in which they reside, due to the shared sovereignty between each state and the federal government. Kentucky, Massachusetts, Pennsylvania, and Virginia use the term commonwealth rather than state in their full official names. States are the primary subdivisions of the United States and possess a number of powers and rights under the United States Constitution, such as regulating intrastate commerce, running elections, creating local governments, and ratifying constitutional amendments. Each state has its own constitution grounded in republican principles, and government consisting of executive, legislative, and judicial branches. All states and their residents are represented in the federal Congress, a bicameral legislature consisting of the Senate and the House of Representatives. Each state is represented by two Senators, while Representatives are distributed among the states in proportion to the most recent constitutionally mandated decennial census. Additionally, each state is entitled to select a number of electors to vote in the Electoral College, the body that elects the President of the United States, equal to the total of Representatives and Senators in Congress from that state. Article IV, Section 3, Clause 1 of the Constitution grants to Congress the authority to admit new states into the Union. Since the establishment of the United States in 1776, the number of states has expanded from the original 13 to 50. Each new state has been admitted on an equal footing with the existing states. The following table is a list of all 50 states and their respective dates of statehood. The first 13 became states in July 1776 upon agreeing to the United States Declaration of Independence, and each joined the first Union of states between 1777 and 1781, upon ratifying the Articles of Confederation, its first constitution. ( A separate table is included below showing AoC ratification dates. ) These states are presented in the order in which each ratified the 1787 Constitution, thus joining the present federal Union of states. The date of admission listed for each subsequent state is the official date set by Act of Congress.

Also, the Constitution is silent on the question of whether states have the power to secede from the Union, but the Supreme Court held that a state can not unilaterally do so in Texas v. White ( 1869 ). Jump up ^ Also known as the `` Three Lower Counties Upon Delaware. '' Delaware became a state on June 15, 1776, when the Delaware Assembly formally adopted a resolution declaring an end to Delaware 's status as a colony of Great Britain and establishing the three counties as an independent state under the authority of `` the Government of the Counties of New Castle, Kent and Sussex Upon Delaware. '' Jump up ^ Between 1749 and 1764 the provincial governor of New Hampshire, Benning Wentworth, issued approximately 135 grants for unoccupied land claimed by New Hampshire west of the Connecticut River ( in what is today southern Vermont ), territory that was also claimed by New York. The resulting `` New Hampshire Grants '' dispute led to the rise of the Green Mountain Boys, and the later establishment of the Vermont Republic. New Hampshire 's claim upon the land was extinguished in 1764 by royal order of George III, and in 1790 the State of New York ceded its land claim to Vermont for 30,000 Dollars. Jump up ^ The Virginia General Assembly adopted legislation on December 18, 1789 separating its `` District of Kentucky '' from the rest of the State and approving its statehood. Jump up ^ The exact date upon which Ohio became a state is unclear. On April 30, 1802 the 7th Congress had passed an act `` authorizing the inhabitants of Ohio to form a Constitution and state government, and admission of Ohio into the Union. '' ( Sess. 1, ch. 40, 2 Stat. 173 ) On February 19, 1803 the same Congress passed an act `` providing for the execution of the laws of the United States in the State of Ohio. '' ( Sess. 2, ch. 7, 2 Stat. 201 ) Neither act, however, set a formal date of statehood. An official statehood date for Ohio was not set until 1953, when the 83rd Congress passed a Joint resolution `` for admitting the State of Ohio into the Union '', ( Pub. L. 83 -- 204, 67 Stat. 407, enacted August 7, 1953 ) which designated March 1, 1803, as that date. Jump up ^ The Massachusetts General Court passed enabling legislation on June 19, 1819 separating the `` District of Maine '' from the rest of the State ( an action approved by the voters in Maine on July 19, 1819 by 17,001 to 7,132 ) ; then, on February 25, 1820, passed a follow - up measure officially accepting the fact of Maine 's imminent statehood. Jump up ^ On May 13, 1862, the General Assembly of the Restored Government of Virginia passed an act granting permission for creation of West Virginia. Later, by its ruling in Virginia v. West Virginia ( 1871 ), the Supreme Court implicitly affirmed that the breakaway Virginia counties did have the proper consents necessary to become a separate state. Jump up ^ When President Benjamin Harrison signed the statehood proclamations for North and South Dakota he shuffled the papers on his desk and covered up all but the signature line of the documents. No one knows which state he signed into existence first. North Dakota 's proclamation was published first in the Statutes at Large, as it is first in alphabetical order. ^ Jump up to : Brought into existence within moments of each other on the same day, North and South Dakota are the nation 's only twin - born states.
