Flag Day is a celebration of the American flag that occurs each year on the anniversary of the flag’s official adoption, June 14.
What we know fondly as the “Stars and Stripes” was adopted by the Continental Congress as the official American flag on June 14, 1777, in the midst of the Revolutionary War. Colonial troops fought under many different flags with various symbols—rattlesnakes, pine trees, and eagles—and slogans—”Don’t Tread on Me,” “Liberty or Death,” and “Conquer or Die,” to name a few.
The Declaration of Independence made the adoption of an American flag necessary. Previously, each colony or special interest had its own flag.
On the 14th of June, Congress made the following resolution: “The flag of the United States shall be thirteen stripes, alternate red and white, with a union of thirteen stars of white on a blue field …” Official announcement of the new flag was not made until Sept. 3, 1777.
