Do you know which U.S. state was the very first to say “yes” to the Federal Constitution? You might be surprised to know that it wasn’t one of the larger or more powerful colonies. Instead, that historic moment belongs to Delaware, a small state with a big place in American history. Let us find out about this U.S. State's history in this article.

What was the First State to Ratify the U.S. Constitution?

The first U.S. state to ratify the Federal Constitution was Delaware. On 7 December 1787, Delaware’s ratifying convention voted unanimously, 30–0, in favour of adopting the new Constitution. This decisive action earned Delaware its enduring nickname: “The First State.” 

According to Ben’s Guide to the U.S. Government, Delaware’s swift approval helped set the ratification process in motion for the rest of the country. It was on December 7, 1787, that Delaware was the first state to vote in favour of it.

Why was Delaware the first state to ratify the Constitution?

Another reason why Delaware was a small state and stood to gain from a strong federal government that treated all states more equally. The Constitution promised protection and fair representation, which appealed greatly to Delaware’s leaders. 

Moreover, Delaware was the state that led the way and paved the path for others to follow in building a unified federal system. 

There was also little internal disagreement. Unlike some states where debates dragged on for months, Delaware’s delegates were largely aligned. That unity made the decision quick and clear.

How many states originally ratified the Constitution?

Originally, nine out of thirteen states were required to ratify the Constitution for it to take effect as law. That milestone was reached on June 21, 1788, when New Hampshire became the ninth state to ratify it. 

As explained by the National Constitution Centre, this moment officially brought the Constitution into effect, even though several states ratified later.

What happened after Delaware ratified?

After Delaware’s decision, other states soon followed, including Pennsylvania, New Jersey, Georgia, and Connecticut. 

  • Each ratification added momentum and legitimacy to the new framework of government.

  • By May 1790, all thirteen original states had ratified the Constitution, with Rhode Island being the last.

To conclude, Delaware’s early ratification wasn’t just symbolic, as it demonstrated confidence in a new national vision at a time of uncertainty.
