The U.S. Bicentennial was an array of observances and celebrations during the mid-1970s, ending with a celebration July 4, 1976, for the 200th anniversary of the adoption of the Declaration of Independence. Pres. Richard M. Nixon created the American Revolution Bicentennial Commission in 1969. Originally to be staged in either Boston or Philadelphia, the celebration spread out across the nation. Queen Elizabeth II and her husband, Prince Philip, made a special state visit to tour the country.
