The 1926 United States Sesquicentennial commemorated the nation’s 150th anniversary, between the 1876 centennial and America250.
The sesquicentennial marked 150 years since the Declaration of Independence. Philadelphia hosted a large international exposition, renewing the city’s association with the founding document and with national anniversary celebrations.
The event included exhibitions, parades, and commemorative architecture, although it is generally remembered as less financially successful than planners hoped. The United States also issued commemorative coins, including a half dollar showing George Washington and Calvin Coolidge. Because sesquicentennial means 150th anniversary, it falls exactly halfway between the 100th anniversary in 1876 and the 200th anniversary in 1976.
