The 1818 Flag, the 20 Star Flag

The 1818 Flag: Realizing that the addition of a new star and new stripe for each new State was impractical, Congress passed the Flag Act of 1818 which returned the flag design to 13 stripes and specified 20 stars for the 20 states.

This Flag became the Official United States Flag on April 13th, 1818. Five stars were added for the admission of Tennessee (the 16th State on June 1st, 1796), Ohio (the 17th State on March 1st, 1803), Louisiana (the 18th State on April 30th, 1812), Indiana (the 19th State on December 11th, 1816), and Mississippi (the 20th State on December 10, 1817), and was to last for just one year.

The only President to serve under this flag was James Monroe (1817-1825).
