Grand Union Flag (1776) - First National Flag of the United States #1393394 (License: Personal Use)

This flag, also known as the Continental Colors or Cambridge Flag, was adopted by the Continental Congress in December 1775 and first raised by General George Washington on January 1, 1776, at Prospect Hill. Its 13 red-and-white stripes represented the original colonies, while the Union Jack in the canton reflected continued loyalty to the Crown before the Declaration of Independence. It served as the de facto national flag until the Stars and Stripes replaced it in 1777.
