Statehood Dates

US States Dates and Order of Statehood

Statehood simply means the status of being one of the states of the US. Delaware was the very first state admitted to the Union in 1787. The United States most recent state admitted to the Union was Hawaii in 1959. A state in the United States is defined as a geographical boundary that holds legislative, executive, and judicial authority below the federal government. There are currently 50 states bound together in the Union. As of 2020, there has been significant interest in granting District of Columbia (DC) statehood as well as Puerto Rico, the oldest colony. States admitted to the statehood are listed below. You can sort in order of admission dates or alphabetical by state.
