Which 1876 event served as the centerpiece of America’s first nationwide centennial celebration before America250?

The Centennial Exposition served as the centerpiece of America’s first nationwide centennial celebration before America250.

Held in Philadelphia in 1876, the exposition marked the 100th anniversary of the Declaration of Independence. Its official name was the International Exhibition of Arts, Manufactures and Products of the Soil and Mine, but it is widely known as the Centennial Exposition or Centennial Exhibition.

The event occupied an area in West Fairmount Park and displayed industrial products, inventions, artworks, and exhibits from the United States and other countries. It introduced many visitors to new technologies and manufacturing achievements during a period of rapid industrial growth.

The exposition is distinct from later world’s fairs. The World’s Columbian Exposition took place in Chicago in 1893, the Louisiana Purchase Exposition in St. Louis in 1904, and the Pan-American Exposition in Buffalo in 1901. Philadelphia’s 1876 event was specifically tied to the nation’s first hundred years.
