Which 1976 milestone preceded America’s 250th anniversary by 50 years?

The United States Bicentennial in 1976 preceded America’s 250th anniversary by 50 years.

The Bicentennial marked 200 years since the Declaration of Independence was adopted in 1776. Its nationwide observance included parades, exhibitions, historical programs, public ceremonies, and specially designed postage stamps and coins.

The 1976 celebration was a major predecessor to the 2026 Semiquincentennial. Both anniversaries connect national commemoration with the Declaration, although the 1976 event marked 200 years and the 2026 event marks 250.

The word “centennial” means a 100th anniversary, “bicentennial” means 200th, and “tricentennial” means 300th. The United States’ next 100-year anniversary milestone after 2026 will be its Tricentennial in 2076.
