Washington, D.C. (pronounced in English: [ˈwɒʃɪŋtən diː siː, ˈwɔːʃɪŋtən diː siː] (listen )) is the capital and federal district of the United States. A.D. is the abbreviation for District of Columbia, where the city is located. The city of Washington and the District of Columbia are coextensive with each other, governed by a single government, which is unique in the country, and for this reason, they are commonly considered the same administrative entity. This was not always the case, however, as other cities existed within the boundaries of the District of Columbia until 1871, when they were gradually merged with Washington, D.C. through an Act of Congress. The city has two historical names, Federal City and Washington City. The District of Columbia, officially formed on July 16, 1790, is the federal district of the United States, as specified by the US Constitution, with limited local power. The US Congress has absolute authority over its legislature, which has veto power. Washingtonians do not have voting representatives in Congress. Washington, D.C. was formed through land ceded by the states of Maryland and Virginia. In 1847, the region that had been ceded by Virginia was returned, almost the entirety of this area is now Arlington County. The construction of Washington began in 1792, being inaugurated in 1800, the same year that it became the North American capital. Washington was named after the first President of the United States, George Washington, while the term District of Columbia derives from an early poetic name for the United States, Columbia.Washington, D.C. is situated in the east of the country on the north bank of the Potomac River. According to the 2020 national census, its population is almost 690,000, while its metropolitan area has about 6.4 million inhabitants (almost 10 million together with the Baltimore metropolitan area, located 100 km from Washington). It is the 20th most populous city in the country. Washington is home to the headquarters of the three arms of the United States government, the Legislative, Executive and Judiciary. In addition, the city also houses the headquarters of the International Monetary Fund, the World Bank, the Organization of American States, among several other national and international institutions.
