The 1876 Centennial Exposition was held in Philadelphia, an earlier United States anniversary celebration related to America250.
Officially called the International Exhibition of Arts, Manufactures, and Products of the Soil and Mine, the exposition ran from May 10 to November 10, 1876. It celebrated the 100th anniversary of the Declaration of Independence and took place in Fairmount Park, west of central Philadelphia.
The exposition was the first official world’s fair held in the United States. Nearly 10 million people attended, and 37 countries participated. Exhibits showcased industrial machinery, agricultural products, art, education, science, and manufacturing. The event also introduced or popularized technologies and products, including Alexander Graham Bell’s telephone.
Philadelphia’s choice reflected its Revolutionary importance: the Declaration had been debated and adopted there, and Independence Hall remained a powerful national symbol. America250 returns attention to the same city because Philadelphia was a central location in the founding story and in the 1776 anniversary itself.
