 Washington , D.C. , formally the District of Columbia and commonly referred to as " Washington " , " the District " , or simply " D.C. " , is the capital of the United States . The signing of the Residence Act on July 16 , 1790 , approved the creation of a capital district located along the Potomac River on the country 's East Coast . The U.S. Constitution provided for a federal district under the exclusive jurisdiction of the Congress and the District is therefore not a part of any U.S. state .

 The states of Maryland and Virginia each donated land to form the federal district , which included the pre @-@ existing settlements of Georgetown and Alexandria . Named in honor of George Washington , one of the United States ' founding fathers and the leader of the American Continental Army who won the Revolutionary War , the City of Washington was founded in 1791 to serve as the new national capital . In 1846 , Congress returned the land originally ceded by Virginia ; in 1871 , it created a single municipal government for the remaining portion of the District .
