What name was given to the 1777 flag that became the first official flag of the United States?

The name commonly given to the first official United States flag adopted in 1777 is the Stars and Stripes.

The Second Continental Congress passed the Flag Resolution on June 14, 1777. It specified thirteen alternating red and white stripes and thirteen white stars on a blue field, representing the thirteen states or former colonies. The resolution did not prescribe the stars’ arrangement, and early flags used several patterns.

The flag is also known as the American flag, the U.S. flag, and the Star-Spangled Banner. The earlier Continental Colors, which combined thirteen stripes with a British Union Jack, was used during the early Revolutionary War but was not the final official design. The famous Star-Spangled Banner flown over Fort McHenry in 1814 was a later flag and helped inspire the national anthem.

A popular story credits seamstress Betsy Ross with sewing the first flag, but historians have not found conclusive evidence that she designed or made the flag adopted by Congress. The official design changed as new states joined the Union, while the thirteen stripes remained constant.
