Article History

This is a list of the states of the United States of America and the dates on which they achieved statehood, ordered by date of admission to the union. This list excludes U.S. territories, as they have not been admitted as states, although they are constituents of the United States. This list also excludes the District of Columbia. The original states joined the United States upon ratification of the U.S. Constitution; dates of ratification are marked with an asterisk. All others are dates of admission to the union.
