What 1976 national celebration was the immediate predecessor to America250?

The United States Bicentennial was the immediate predecessor to America250.

Celebrated in 1976, the Bicentennial marked 200 years since the Declaration of Independence was adopted in 1776. It produced nationwide ceremonies, historic preservation projects, exhibitions, parades, commemorative objects, and special public programs.

The 1976 celebration provides the clearest comparison for America250. The 2026 observance marks 250 years, so it is a semiquincentennial rather than a bicentennial. The two anniversaries are separated by fifty years.

The Bicentennial was also notable for its broad national scope. Communities across the country organized local events, while federal agencies and cultural institutions created exhibits and educational materials. Some commemorative architecture and public artworks from 1976 remain visible today.

The term centennial means 100 years, bicentennial means 200, and tricentennial means 300. America250 uses a less familiar numerical term because 250-year anniversaries do not have a common everyday label.
