Philadelphia hosted the 1876 Centennial Exposition remembered in America250 history.
The exposition celebrated the 100th anniversary of the Declaration of Independence and was held in Philadelphia, the city where the Second Continental Congress met and where the Declaration was adopted. Its official name was the International Exhibition of Arts, Manufactures and Products of the Soil and Mine, but it is commonly called the Centennial Exposition.
The event demonstrated industrial technology, manufactured goods, scientific instruments, and cultural achievements from the United States and other countries. It helped establish Philadelphia as a major location for national anniversary observances.
Philadelphia later hosted the Sesquicentennial Exposition in 1926 and remains central to America250 planning. The city’s historical importance does not mean it was the birthplace of every founding document: the Constitution was also drafted in Philadelphia, while the Declaration’s signing involved delegates representing the thirteen colonies.
