<P> 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 . </P> <P> 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 . </P> <Table> <Tr> <Th_colspan="2"> State </Th> <Th> Date (admitted or ratified) </Th> <Th> Formed from </Th> </Tr> <Tr> <Td> </Td> <Td> Delaware </Td> <Td> 000000001787 - 12 - 07 - 0000 December 7, 1787 (ratified) </Td> <Td> Crown Colony of Delaware </Td> </Tr> <Tr> <Td> </Td> <Td> Pennsylvania </Td> <Td> 000000001787 - 12 - 12 - 0000 December 12, 1787 (ratified) </Td> <Td> Crown Colony of Pennsylvania </Td> </Tr> <Tr> <Td> </Td> <Td> New Jersey </Td> <Td> 000000001787 - 12 - 18 - 0000 December 18, 1787 (ratified) </Td> <Td> Crown Colony of New Jersey </Td> </Tr> <Tr> <Td> </Td> <Td> Georgia </Td> <Td> 000000001788 - 01 - 02 - 0000 January 2, 1788 (ratified) </Td> <Td> Crown Colony of Georgia </Td> </Tr> <Tr> <Td> 5 </Td> <Td> Connecticut </Td> <Td> 000000001788 - 01 - 09 - 0000 January 9, 1788 (ratified) </Td> <Td> Crown Colony of Connecticut </Td> </Tr> <Tr> <Td> 6 </Td> <Td> Massachusetts </Td> <Td> 000000001788 - 02 - 06 - 0000 February 6, 1788 (ratified) </Td> <Td> Crown Colony of Massachusetts Bay </Td> </Tr> <Tr> <Td> 7 </Td> <Td> Maryland </Td> <Td> 000000001788 - 04 - 28 - 0000 April 28, 1788 (ratified) </Td> <Td> Crown Colony of Maryland </Td> </Tr> <Tr> <Td> 8 </Td> <Td> South Carolina </Td> <Td> 000000001788 - 05 - 23 - 0000 May 23, 1788 (ratified) </Td> <Td> Crown Colony of South Carolina </Td> </Tr> <Tr> <Td> 9 </Td> <Td> New Hampshire </Td> <Td> 000000001788 - 06 - 21 - 0000 June 21, 1788 (ratified) </Td> <Td> Crown Colony of New Hampshire </Td> </Tr> <Tr> <Td> 10 </Td> <Td> Virginia </Td> <Td> 000000001788 - 06 - 25 - 0000 June 25, 1788 (ratified) </Td> <Td> Crown Colony of Virginia </Td> </Tr> <Tr> <Td> 11 </Td> <Td> New York </Td> <Td> 000000001788 - 07 - 26 - 0000 July 26, 1788 (ratified) </Td> <Td> Crown Colony of New York </Td> </Tr> <Tr> <Td> 12 </Td> <Td> North Carolina </Td> <Td> 000000001789 - 11 - 21 - 0000 November 21, 1789 (ratified) </Td> <Td> Crown Colony of North Carolina </Td> </Tr> <Tr> <Td> 13 </Td> <Td> Rhode Island </Td> <Td> 000000001790 - 05 - 29 - 0000 May 29, 1790 (ratified) </Td> <Td> Crown Colony of Rhode Island and Providence Plantations </Td> </Tr> <Tr> <Td> 14 </Td> <Td> Vermont </Td> <Td> 000000001791 - 03 - 04 - 0000 March 4, 1791 (admitted) </Td> <Td> Vermont!
