What earlier anniversary celebration did America250 follow in the United States?

America250 follows the United States Bicentennial, the country’s 200th-anniversary celebration held in 1976.

The Bicentennial commemorated the adoption of the Declaration of Independence in 1776. Its central anniversary date was July 4, 1976, exactly 200 years after the Second Continental Congress adopted the document.

Celebrations spread across the country during the mid-1970s. They included parades, historic reenactments, exhibitions, commemorative objects, and special public events. The period also featured the American Freedom Train, which toured the country carrying artifacts connected with American history.

The two anniversaries use different numerical names. “Bicentennial” means 200 years, while “Semiquincentennial” means 250 years. The 2026 commemoration is therefore not a repeat of the Bicentennial but the next major quarter-century milestone in the national anniversary sequence.
