America250 follows which earlier U.S. anniversary celebrated on July 4, 1976?

America250 follows the United States Bicentennial, celebrated on July 4, 1976.

The Bicentennial marked 200 years since the Second Continental Congress adopted the Declaration of Independence. Its nationwide observances included parades, fireworks, exhibitions, commemorative objects, and tall-ship events. President Gerald Ford participated in the national celebrations.

The 1976 commemoration is the most direct predecessor to America250. Adding another 50 years to 1976 produces 2026, the year of the United States’ 250th anniversary. The two celebrations therefore share the same July 4 historical reference point while marking different anniversary numbers.

The terms can be confused because centennial means 100 years, bicentennial means 200, and semiquincentennial means 250. The United States also observed a centennial in 1876 and a sesquicentennial in 1926, but neither is the immediate predecessor to America250.
