The 1926 Sesquicentennial Exposition for America’s 150th anniversary was held in Philadelphia.
The exposition marked 150 years since the adoption of the Declaration of Independence and also looked back to Philadelphia’s earlier Centennial Exposition of 1876. It opened on May 31, 1926, with the principal anniversary date falling on July 4.
President Calvin Coolidge was associated with the opening ceremonies. The fair included exhibition buildings, industrial displays, cultural attractions, and entertainment, although it did not achieve the same lasting reputation as the 1876 exposition.
“Sesquicentennial” means a 150th anniversary. Philadelphia’s repeated role in the 1876 and 1926 celebrations reflects its central place in the revolutionary history commemorated again by America250 in 2026.
