The United States celebrated its bicentennial in 1976, the 200th anniversary before America250.
The bicentennial marked two centuries since the Declaration of Independence was adopted in 1776. Celebrations included parades, exhibitions, concerts, public ceremonies, and special projects across the country, with Philadelphia serving as one of the principal historic locations.
The 1976 observance was a major national event during the presidency of Gerald Ford. The United States Mint issued commemorative coins, and the Postal Service released stamps connected with the anniversary. Communities also organized local festivals and historical programs.
America250 follows the same anniversary arithmetic: 1776 plus 250 years equals 2026. The terms should not be interchanged: “bicentennial” means 200 years, while “semiquincentennial” means 250 years.
