National Capitals
Washington, D.C.
Since 1800, Washington, D.C. has served as the federal capital of the United States. The U.S. Constitution grants Congress the power to establish a federal district for the seat of government. The Residence Act of 1790 designated the Potomac River area for this purpose, leading to the establishment of Washington, D.C.
Historical Sites
Before Washington, D.C., several cities served as temporary capitals. These included Philadelphia (Independence Hall, Congress Hall), New York City (Federal Hall), and others during the periods of the Second Continental Congress and the Congress of the Confederation. Congress has met outside Washington D.C. ceremonially on rare occasions, such as in Philadelphia in 1987 and New York in 2002.
