What 200th-anniversary celebration preceded America250’s 250th-anniversary observance?

The United States Bicentennial was the 200th-anniversary celebration that preceded America250. It marked the 200th anniversary of the Declaration of Independence and reached its central date on July 4, 1976.

The bicentennial produced nationwide ceremonies, historical programs, public works, commemorative objects, and major events. The celebration included the Operation Sail tall-ship gathering, which brought international sailing vessels to New York Harbor.

The word “bicentennial” means a 200th anniversary. The term “centennial” refers to 100 years, “sesquicentennial” to 150 years, and “tricentennial” to 300 years. America250 is therefore not another bicentennial; it is a semiquincentennial.

The two celebrations are separated by 50 years. The 1976 bicentennial looked back to 1776, while the 2026 America250 observance marks 250 years since the same founding declaration.
