The Second Continental Congress adopted the stars and stripes design for the flag of the United States.

The Second Continental Congress (1775–1781) was the meeting of delegates from the Thirteen Colonies that united in support of the American Revolution and Revolutionary War, which established American independence from Great Britain. The Congress constituted a new federation that it first named the United Colonies of North America, and in 1776, renamed the United States of America. The Congress began convening in present-day Independence Hall in Philadelphia, on May 10, 1775, with representatives from 12 of the 13 colonies, following the Battles of Lexington and Concord, the first battles of the Revolutionary War, which were fought on April 19, 1775.
