On July 4th,1819 the 21-Star Flag became the Official United States Flag.

Note from history: A star was added for the admission of Illinois (December 3rd, 1818) and was one of the shortest-lived US flags destine to last for just one year.

The only President to serve under this flag was James Monroe.
