What was the name of Philadelphia’s exposition celebrating 150 years of American independence in 1926?

Philadelphia’s 1926 exposition celebrating 150 years of American independence was the Sesquicentennial Exposition.

The fair commemorated the 150th anniversary of the Declaration of Independence. It followed Philadelphia’s 1876 Centennial Exposition and preceded the nationwide Bicentennial observances of 1976. The term “sesquicentennial” means a 150th anniversary.

The exposition included scientific, artistic, commercial, and historical displays. Although millions of people attended, the event faced financial and construction problems, and many exhibits were still being completed after the opening. Its mixed results made it less celebrated than the 1876 exposition.

The 1926 event is relevant to America250 because it shows how the United States repeatedly used Philadelphia and its founding history as settings for national commemorations. The 2026 anniversary continues that long pattern while reaching the 250-year milestone.
