What was the 1876 Philadelphia Centennial Exposition officially classified as in the United States?

The 1876 Philadelphia Centennial Exposition was the first official world’s fair held in the United States.

Its formal title was the International Exhibition of Arts, Manufactures, and Products of the Soil and Mine. The event brought together exhibits from the United States and dozens of foreign countries in Fairmount Park.

The exposition celebrated the centennial of the Declaration of Independence while also advertising American industrial and technological progress. Its displays included machinery, agricultural equipment, consumer goods, art, and scientific inventions.

It should not be confused with a state fair or a purely domestic celebration. World’s fairs are international exhibitions intended to display achievements and products from multiple nations. Later American examples included the 1893 World’s Columbian Exposition in Chicago and the 1939 New York World’s Fair.
