What 200th-anniversary event preceded America250 as the United States’ previous major national anniversary?

The United States Bicentennial was the 200th-anniversary event that preceded America250.

The Bicentennial took place in 1976, marking 200 years since the Declaration of Independence. It was celebrated across the country with parades, exhibitions, fireworks, historic commemorations, and special products issued by government agencies and private organizations.

America250 follows the same anniversary sequence at a larger number: 250 years rather than 200. The formal term for 250 years is semiquincentennial, while “bicentennial” means a 200th anniversary.

The Bicentennial is also associated with the 1976 United States Mint quarter, whose reverse showed a colonial drummer and a torch surrounded by 13 stars. That coin design became one of the most recognizable objects of the earlier national celebration.
