Philadelphia hosted the 1876 Centennial Exposition, an earlier major U.S. anniversary observance related to America250.
Held in Philadelphia’s Fairmount Park, the exposition marked the 100th anniversary of the Declaration of Independence. It opened on May 10, 1876, and presented industrial machinery, manufactured products, art, agriculture, and exhibits from the United States and other countries.
Philadelphia was a natural setting because the city had been central to the American Revolution and was where the Declaration of Independence had been debated and adopted. The exposition also helped present the United States as an increasingly industrial and technologically capable nation.
The Centennial Exposition is distinct from the 1926 Sesquicentennial Exposition and the 1976 Bicentennial celebrations. Those events marked 150 and 200 years respectively. America250 continues the pattern of nationally significant anniversary observances, with Philadelphia again playing a prominent historical role.
