Which state was the 14th to join the United States?

Vermont was the 14th state to join the United States, achieving statehood on March 4, 1791. Vermont's admission followed a complicated history, as it was initially an independent republic known as the Vermont Republic from 1777 to 1791. Although it declared independence during the American Revolutionary War, it eventually sought to join the Union to gain legitimacy and support. Its admission to the Union as a state was significant, as it was the first state added after the original thirteen colonies, and it played a key role in the balance of power between free and slave states in the early years of the United States. The other options, such as New Hampshire, Virginia, and Massachusetts, were among the original thirteen colonies and joined the Union much earlier, before Vermont's admission.
