The United States held its Sesquicentennial Exposition in 1926 before the America250 anniversary.
The exposition took place in Philadelphia to commemorate 150 years since the Declaration of Independence. It opened in May 1926 and continued into November, featuring exhibits, entertainment, commercial displays, and national participation.
The word “sesquicentennial” means a 150th anniversary. The 1926 event therefore falls exactly between the 1876 Centennial Exposition and the 1976 Bicentennial celebration. It was one of the major national commemorations held before America250.
Philadelphia was chosen because it was the location of the Continental Congress when the Declaration was adopted. The city’s repeated role in the 1876, 1926, and 1976 anniversaries reflects its strong association with American independence and founding history.
