Which U.S. anniversary in 1976 preceded the America250 semiquincentennial in 2026?

The United States Bicentennial in 1976 preceded the America250 semiquincentennial in 2026.

The bicentennial marked 200 years since the Declaration of Independence. Its celebrations spread across the country and included parades, exhibitions, educational programs, public works, patriotic decorations, and special issues of coins and stamps. July 4, 1976, was the central date.

The 2026 semiquincentennial follows the same independence-based timeline at a different interval. Two hundred years after 1776 was 1976; 250 years after 1776 is 2026. The names therefore describe different anniversaries rather than competing titles for the same event.

The bicentennial also produced lasting visual symbols, including the 1976 American Revolution Bicentennial logo. It is sometimes confused with the U.S. centennial of 1876, which marked 100 years and coincided with the Philadelphia Centennial Exposition.
