What earlier major anniversary of U.S. independence was celebrated in 1976?

The earlier major anniversary of U.S. independence celebrated in 1976 was the Bicentennial. It marked 200 years since the Declaration of Independence was adopted in 1776.

The 1976 observance involved celebrations, commemorative objects, exhibitions, public ceremonies, and projects across the United States. The anniversary took place during the presidency of Gerald Ford and became one of the largest nationwide commemorations in American history.

The word bicentennial means a 200th anniversary. America250 uses the corresponding term semiquincentennial for the 250th anniversary in 2026. A centennial marks 100 years, a sesquicentennial marks 150 years, and a tricentennial marks 300 years.

The 1976 Bicentennial provides a direct historical precedent for America250. Both anniversaries connect a modern national celebration with the Declaration’s adoption on July 4, although the scale and programs of each commemoration differ.
