Grand Union Flag - First National Flag of the United States (1775-1777) #1820672 (License: Personal Use)

This historical flag, also known as the Continental Colors or Cambridge Flag, combined the 13 stripes symbolizing the original colonies with the British Union Jack in the canton, reflecting loyalty to the Crown before full independence. It was first flown by General George Washington on January 1, 1776, at Prospect Hill in Massachusetts, marking a pivotal moment in early American military identity. Though replaced by the Stars and Stripes in 1777, it remains a key symbol of the transition from colonial rule to revolution.

Used in educational, historical, and museum contexts to illustrate pre-independence American symbolism; ideal for pages about Revolutionary War history, flag evolution, or U.S. national symbols.
