"During the American Revolution, the Continental Congress adopts a resolution stating that “the flag of the United States be thirteen alternate stripes red and white” and that “the Union be thirteen stars, white in a blue field, representing a new Constellation.” The national flag, which became known as the “Stars and Stripes,” was based on the “Grand Union” flag, a banner carried by the Continental Army in 1776 that also consisted of 13 red and white stripes. According to legend, Philadelphia seamstress Betsy Ross designed the new canton for the Stars and Stripes, which consisted of a circle of 13 stars and a blue background, at the request of General George Washington. Historians have been unable to conclusively prove or disprove this legend."
