On this date in 1777 the Continental Congress approved a national flag:
Resolved, that the Flag of the thirteen United States shall be thirteen stripes, alternate red and white; that the Union be thirteen stars, white on a blue field, representing a new constellation.
In 1916 President Wilson issued a proclamation declaring June 14 Flag Day.
The present design of the flag was established in 1818 — thirteen stripes to represent the original states and a star for each state. The current flag with 50 stars was established on July 4, 1960, when Hawaii was admitted to the Union.
The Star Spangled Banner at Fort McHenry during the War of 1812 had 15 stars and 15 stripes.
