Cool fact for the day!

🇺🇸 Did you know the United States officially adopted its name 250 years ago today?

On September 9, 1776, the Continental Congress resolved that official commissions and documents would use “United States” instead of “United Colonies.”

A new nation had declared its independence—and now it had the name it would carry into history.
