It is believed the first annual recognition of the U.S. flag's birthday dates back to 1885. On June 14th of that year, a school teacher named BJ Cigrand organized a group of children to observe the 108th anniversary of the official adoption of The Stars and Stripes. Cigrand is now known as the Father of Flag Day.
The first celebration of the U.S. flag's birthday was held eight years earlier in 1877 --- exactly 100 years after the Second Continental Congress passed the Flag Resolution, which stated:
Resolved, that the flag of the thirteen United States be thirteen stripes, alternate red and white; that the union be thirteen stars, white in a blue field, representing a new constellation.
Over the following years as many as 36 state and local governments adopted the annual observance. For over 30 years Flag Day remained a state and local celebration.
In 1916, President Woodrow Wilson proclaimed the anniversary of the Flag Resolution of 1777 to be a nationally observed event. However, it was not designated as National Flag Day until August 3rd, 1949, when an Act of Congress designated June 14th of each year as National Flag Day.
