Which 1976 national celebration marked the 200th anniversary that America250 will follow 50 years later?

The United States Bicentennial was the 1976 national celebration that America250 will follow 50 years later.

The bicentennial marked 200 years since the Declaration of Independence was adopted in 1776. Preparations began years in advance and included public events, historical programs, exhibitions, commemorative objects, and a wide variety of local celebrations across the country.

The anniversary also produced lasting visual symbols, including the red, white, and blue Bicentennial logo and specially issued United States postage stamps and coins. Philadelphia hosted major events because of its central role in the Declaration and the American Revolution.

America250 is not another name for the 1976 celebration. “Bicentennial” refers to 200 years, while “semiquincentennial” refers to 250 years. The two observances are linked because both count anniversaries from the 1776 declaration.
