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. On July 16, 1790, the United States Congress approved the creation of a permanent national capital as permitted by the U.S. Constitution. The federal district is therefore not a part of any U.S. state. It was formed from land along the Potomac River donated by the states of Maryland and Virginia; however, the Virginia portion was returned by Congress in 1846.

A new capital city named after George Washington was founded in 1791 to the east of the preexisting port of Georgetown. Congress consolidated the City of Washington, Georgetown, and the remaining unincorporated area within the District under a single government in 1871. Washington, D.C., shares its name with the U.S. state of Washington, located on the country's Pacific coast. The centers of all three branches of the federal government of the United States are located in the District, as are many of the nation's monuments and museums. It had a population of 437,571 people in 1920. Washington is approximately 200 miles West of Atlantic City by road. Walter Reed Army Medical Centre, where Jimmy Darmody received surgery for his injuries during his service in the US Army, is in Washington, D.C. ("Home")
