The United States was formed following the American Revolutionary War. This conflict began with the Declaration of Independence in 1776 and ended in 1783. However, the U.S. wasn’t truly formed until the official ratification of the Constitution of the United States in 1788. After that, former colonies that accepted and confirmed the Constitution became states. Take a look at the 10 oldest states in the United States, the ones that accepted the Constitution first!

What Are The 10 Oldest States in the U.S.?

The early states did not simply appear out of thin air. Instead, they were previously one of the 13 colonies. Since this list is going to look at the oldest states in the United States, it’s only proper to consider them by the date they joined the union and not the date the original colony was founded or when the state broke away from the British.

Specifically, we’re going to list the states according to the day they joined the U.S. by ratifying the Constitution of the United States. The list is not going to focus on when they declared independence from the British.

People are often confused about how Delaware and other states apparently became a part of the union before the official ratification of the Constitution and the formation of the new government as the United States.

Well, representatives in nine states needed to ratify the document before the government could take effect under the new laws. Once nine states committed to the Constitution, the whole thing became official.

10. Virginia

Date of StatehoodJune 25, 1788

Virginia became a state on June 25, 1788, and it just missed out on being the crucial ninth state to ratify the Constitution. The Virginia Ratifying Convention consisted of 166 individuals that met in 1788 to determine whether to join the union. From June 2 until June 27, the group met. The vote passed with 89 voting for ratification and 79 voting against it. The decision was published on June 25, 1788.

New Hampshire was the ninth state to ratify the Constitution. The motion needed two-thirds of the former colonies to accept the document, rounded up to nine states. On June 21, 1788, New Hampshire’s government voted to become the ninth state in the union, replacing the Articles of Confederation with the United States Constitution as the fundamental law of the country.

8. South Carolina

South Carolina became the 8th former colony to ratify the constitution on May 23, 1788. The vote was 149 representatives in favor of the ratification and 73 against it. Interestingly, the state would only stay a part of the union for 72 years before becoming the first to secede from the U.S. in 1860.

Date of StatehoodDecember 7, 1787

The oldest state in the United States is Delaware. Delaware was the first state to ratify the constitution on December 7, 1787. The vote was passed unanimously by 30 delegates. As a result, Delaware has been called the “State that Started a Nation” since it was the first one to put its faith in the new federal government.

The 10 oldest states in the United States accepted the Constitution for different reasons. Some of them would later abandon that government and its laws during the Civil War. However, the Constitution and its many amendments continue to be the law of the land today.
