Philadelphia hosted the Sesquicentennial Exposition marking America’s 150th anniversary in 1926.
The exposition commemorated 150 years since the Declaration of Independence. Philadelphia was selected because of its central role in the American Revolution and its connection with the Declaration, the Second Continental Congress, and Independence Hall.
The event was held in South Philadelphia and included exhibition halls, pavilions, amusement attractions, and displays of American products and technological achievements. Although it was designed as a major national celebration, attendance and financial results were less successful than organizers had hoped.
Philadelphia’s sequence of anniversary events is notable. It hosted the Centennial Exposition in 1876, the Sesquicentennial Exposition in 1926, and became a leading city for planning the United States Semiquincentennial in 2026. The three anniversaries represent 100, 150, and 250 years.
