Grand Union Flag - First National Flag of the United States (1775-1777) #1740359 (License: Personal Use)

This flag, also known as the Continental Colors or Cambridge Flag, was first raised by General George Washington on January 1, 1776, at Prospect Hill in Massachusetts. It combined the British Union Jack in the canton with thirteen alternating red and white stripes to represent the Thirteen Colonies’ unity while still acknowledging ties to Britain. Though short-lived, it served as a crucial transitional symbol before the adoption of the Stars and Stripes.
