Philadelphia served as the temporary U.S. capital from 1790 to 1800 while Washington, D.C., was being constructed.

Since Philadelphia was the temporary capital of the United States from 1790 to 1800, it played a significant part in American history. While Washington, D.C., was being prepared as the permanent capital, Congress met at Congress Hall during this decade, and the city emerged as the political center of the country. Philadelphia was a perfect fit for this position because of its center location among the original 13 states. Being a significant hub for culture and commerce at the period, it was the site of important discussions and choices that shaped the early Republic. The city is a pillar of American heritage because of its rich history, which includes its involvement in the American Revolution and the signing of the Constitution.
