District of Columbia

Washington, D.C. is the capital city of the United States of America. "D.C." stands for the "District of Columbia", the federal district containing the city of Washington. more...

The city is named after George Washington, military leader of the American Revolution and the first President of the United States. The District of Columbia and the city of Washington are coextensive and are governed by a single municipal government, so for most practical purposes they are considered to be the same entity (this was not always the case, though, as Georgetown was a separate city within the District until 1871). However, although there is a municipal government and a mayor, as per Article I, Section VIII, of the United States Constitution, Congress has the sole authority over this federal district. It is commonly known as the District, D.C., or simply Washington. Historically, it was called the Federal City or Washington City.

The District of Columbia, founded on July 16, 1790, is a federal district as specified by the United States Constitution. The U.S. Congress has ultimate authority over the District of Columbia, though it has delegated limited local rule to the municipal government. The land forming the original District came from the states of Virginia and Maryland. However, the area south of the Potomac River (39 mi² or about 100 km²) was returned, or "retroceded", to Virginia in 1847 and now is incorporated into Arlington County and the City of Alexandria. The term "District of Columbia" is derived from an old poetic name for the United States, Columbia, which has fallen out of common use since the early 20th century.
