What was the name of the 1926 Philadelphia exposition commemorating 150 years of American independence before America250?

The 1926 Philadelphia exposition commemorating 150 years of American independence was the Sesquicentennial Exposition.

Held in Philadelphia, the event marked the 150th anniversary of the Declaration of Independence. Its grounds included exhibition buildings, displays, entertainment, and architectural features intended to celebrate American progress and the nation’s revolutionary origins.

The word sesquicentennial means a 150th anniversary. That places the 1926 exposition between the Centennial Exposition of 1876 and the Bicentennial celebrations of 1976. The sequence provides historical context for America250, which marks the next major quarter-century milestone after the bicentennial.

The exposition is sometimes confused with Philadelphia’s 1876 Centennial Exposition because both were large anniversary events in the same city. Their dates and anniversary levels distinguish them: 1876 represented 100 years, while 1926 represented 150.
