On 14 June 1777, the Continental Congress approved the design of the Stars and Stripes as the official flag of the U.S. The first Flag Act was passed on this day stating that "the flag of the United States be made of thirteen stripes, alternate red and white; that the union be thirteen stars, white in a blue field, representing a new Constellation."
Between 1777 and 1960, US Congress passed several acts that changed the shape, design and arrangement of the flag and allowed for additional stars and stripes to be added to reflect the admission of each new state.
Today the flag consists of thirteen horizontal stripes, seven red alternating with 6 white. The stripes represent the original 13 colonies, the stars represent the 50 states of the Union.
