On July 16, 1790, the
Residence Act provided for a new permanent capital to be located on the
Potomac River, the exact area to be selected by President
Washington. As permitted by the U.S. Constitution, the initial shape of the federal district was a square, measuring on each side, totaling . The Residence Act also provided for the selection of a three-member board of commissioners, appointed by the President, charged with overseeing the construction of the new capital. Two other incorporated cities that predated the establishment of the District were also included within the new federal territory:
Georgetown, founded in 1751, and the City of
Alexandria, Virginia, founded in 1749. A new "federal city" called the City of Washington was under construction, partly habitable, on the north bank of the Potomac, to the east of the established settlement at Georgetown. , first mayor of the City of Washington The
Organic Act of 1801 officially organized the District of Columbia and placed the entire federal district under the exclusive control of Congress. At its formation, the District consisted of five political subdivisions: the three cities of Washington, Georgetown, and Alexandria, and the unincorporated rural sections organized into two counties:
Washington County, D.C. to the east of the Potomac and the
Alexandria County, D.C. to the west. It included all of the present Arlington County plus part of what is now the
independent city of Alexandria. The respective laws of Maryland and Virginia were declared still in force. In 1802, the board of commissioners was disbanded, and the City of Washington was officially incorporated. The city's incorporation allowed for a local municipal government consisting of a mayor appointed by the President and two branches of a city council, popularly elected. The local colonial-era governments of Georgetown and Alexandria were also left intact. As such, the citizens of Georgetown retained their popularly elected mayor, as did
the City of Alexandria. In 1812, the council was given the power to elect the mayor of the City of Washington. In 1820, the Congress granted the City of Washington a new charter, which allowed for a mayor popularly elected by voters. The disputes became more political in 1840 when the city elected a member of the anti-Jackson
Whig Party as mayor. Two weeks after the election, members of Congress submitted legislation to alter the charter of the City of Washington to remove the city's elected government. However, the bill was unable to pass the Congress due to disputes among members about the status of slavery in the District. The election of President
William Henry Harrison, who was favorable to residents of the District, assured that the proposed bill would not become law. On July 9, 1846, in response to a voter referendum, Congress retroceded the City of Alexandria and Alexandria County to Virginia. In the years preceding and during the
American Civil War, the District developed a complicated, piecemeal government. Three distinct authorities over Washington County and the two cities, Washington and Georgetown, remained intact. In 1861, as the first step toward political consolidation, those three bodies were granted shared authority over the new
Metropolitan Police Department, founded to enforce the law throughout the District. Its oversight board of five commissioners named by the President included one representing Georgetown, one from the county of Washington, and three from the city of Washington. During the Civil War, the district experienced a large increase in its population; by 1870, the District's population had grown to nearly 132,000. Despite the district's growth, District still had dirt roads and lacked basic sanitation; the situation was so bad that some members of Congress proposed moving the capital elsewhere. To facilitate infrastructure improvements and make the district's government operate more efficiently, Congress passed the
Organic Act of 1871, which created a new government for the entire federal district. This Act effectively combined the City of Washington, Georgetown, and the unincorporated area known then as
Washington County into a single district government for the whole District of Columbia. In the same Organic Act, Congress created a territorial government which consisted of a legislative assembly with an upper house composed of eleven council members appointed by the President and a 22-member house of delegates elected by the people, The territorial government was replaced by a three-member Board of Commissioners, consisting of two members appointed by the President with the approval of the Senate, and a third member selected from the
United States Army Corps of Engineers, This form of government continued for nearly a century. Between 1948 and 1966, six bills were introduced in Congress to provide some form of home rule, but none ever passed. In 1967, President
Lyndon Johnson presented to Congress a plan to reorganize the District's government designed by
David Carliner. The three-commissioner system was replaced by a government headed by a single mayor-commissioner, an assistant mayor-commissioner, and a nine-member district council, all appointed by the president. while the council served three-year terms. The mayor-commissioner could veto ordinances passed by the Council, but the Council could override the veto with a three-fourths vote. Johnson said that the new District government would be more effective and efficient. Each of the district's eight
wards elects a single member of the council and five members, including the chairman, are elected at large. Small neighborhood districts elect 37
Advisory Neighborhood Commissions (ANCs). ANCs traditionally wield a great deal of influence, and the district government routinely considers their suggestions carefully. The Council has the ability to pass local laws and ordinances. However, pursuant to the Home Rule Act all legislation passed by the District of Columbia government, including the district's local budget, remains subject to the approval of Congress. The Home Rule Act specifically prohibits the Council from enacting certain laws that, among other restrictions, would: • lend public credit for private projects; • impose a tax on individuals who work in the District but live elsewhere; • make any changes to the district's
federally mandated height limit; • pass any law changing the composition or jurisdiction of the local courts; • enact a local budget that is not balanced; and • gain any additional authority over the
National Capital Planning Commission,
Washington Aqueduct, or
District of Columbia National Guard. The Home Rule Act prohibits the District from imposing a commuter tax on non-residents, who comprise over 60% of the district's workforce. In addition, over 50% of property in the District is also exempt from taxation. The
Government Accountability Office and other organizations have estimated that these revenue restrictions create a structural deficit in the district's budget of anywhere between $470 million and over $1 billion per year. While Congress typically provides larger grants to the District for federal programs such as
Medicaid and the
local justice system, analysts claim that the payments do not resolve the imbalance. In February 2025, two Republicans in Congress, Representative Andy Ogles, Republican of Tennessee, and Senator Mike Lee, Republican of Utah, introduced a bill to repeal the Home Rule Act of 1973. ==Non-citizen voting==
