The United States Bicentennial was a series of celebrations and observances during the mid-1970s that paid tribute to historical events leading up to the creation of the United States of America as an independent republic. It was a central event in the memory of the American Revolution. The Bicentennial culminated on Sunday, July 4, 1976, with the 200th anniversary of the adoption of the Declaration of Independence by the Founding Father delegates of the Second Continental Congress.
