Calvin Coolidge was president of the United States during Philadelphia’s 1926 Sesquicentennial Exposition.
The Sesqui-Centennial International Exposition opened in Philadelphia on July 4, 1926, marking 150 years since the adoption of the Declaration of Independence. Coolidge was president throughout the exposition and participated in its opening ceremonies.
The event also commemorated the 50th anniversary of Philadelphia’s 1876 Centennial Exposition. It included large exhibition grounds, industrial displays, cultural attractions, and buildings designed for a major international fair. Despite its scale, it is generally remembered less prominently than the 1876 Centennial Exposition and the 1976 Bicentennial.
Coolidge is sometimes confused with Woodrow Wilson, who was president during the First World War, or Herbert Hoover, who succeeded Coolidge in 1929. The 1926 exposition belongs to the Coolidge presidency and forms part of the sequence of national anniversary observances leading to America250.
