The Grand Union Flag

Not to be confused with the Union Flag (UK), the Grand Union Flag is sometimes also known as the Congress Flag and was the first official flag of the United States of America.

The flag was first hoisted in 1775, and was mostly used by the Second Continental Congress, a de facto war government during the American Revolutionary War. As such, it contains the British flag in the canton, along with 13 alternating red and white stripes, which represent the thirteen colonies.
