605-497: A monarch held his or her court, the selection, relocation, founding, or capture of a modern capital city is a highly symbolic event. For example: The capital city is usually but not always a primary target in a war, as capturing it usually guarantees capture of much of the enemy government, victory for the attacking forces, or at the very least demoralization for the defeated forces.

Though Ellicott revised the original L'Enfant plans, including changing some street patterns, L'Enfant is still credited with the city's overall design.

The lowest recorded temperature was −15 °F (−26 °C) on February 11, 1899 , right before the Great Blizzard of 1899 . During a typical year, the city averages about 37 days at or above 90 °F (32 °C) and 64 nights at or below
9317-618: The country exceeded the region in raw resource value, they were not as easily accessible, and often, access to them necessarily had to pass through the Northeast first. The Northeast played a significant role in the foundation of the United States during the late colonial era and in the American Revolutionary War . Pre-revolutionary events like the Gaspee affair , the Boston Massacre , Boston Tea Party , and
9438-645: The countryside, where they enjoyed support from local governments and the traditionally independent civilian frontiersmen. Exceptions to these generalizations include highly centralized states such as France , whose centralized bureaucracies could effectively coordinate far-flung resources, giving the state a powerful advantage over less coherent rivals, but risking utter ruin if the capital were taken. Northeast megalopolis 41°N 74°W / 41°N 74°W / 41; -74 Core combined statistical areas (CSAs) Outlying metropolitan areas The Northeast megalopolis , also known as
9559-481: The district . Alexandria's citizens petitioned Virginia to retake the land it had donated to form the district, a process known as retrocession . The Virginia General Assembly voted in February 1846, to accept the return of Alexandria. On July 9, 1846, Congress went further, agreeing to return all territory that Virginia had ceded to the district during its formation. This left the district's area consisting only of
9680-545: The district over the next few decades. Georgetown's street grid and other administrative details were formally merged with those of the City of Washington in 1895. However, the city had poor housing and strained public works, leading it to become the first city in the nation to undergo urban renewal projects as part of the City Beautiful movement in the early 20th century. The City Beautiful movement built heavily upon
9801-425: The district since 1973, though Congress retains the power to overturn local laws. Washington, D.C., residents are, on the federal level, politically disenfranchised since the city's residents do not have voting representation in Congress; the city's residents elect a single non-voting congressional delegate to the U.S. House of Representatives. The city's voters choose three presidential electors in accordance with
9922-415: The district with a total area of about 3.1 million square feet (288,000 m). Washington Union Station is designed in a combination of architectural styles.

Capital city A capital city or just capital is the municipality holding primary status in
10043-526: The district's border with Virginia and has two major tributaries, the Anacostia River and Rock Creek . Tiber Creek , a natural watercourse that once passed through the National Mall , was fully enclosed underground during the 1870s. The creek also formed a portion of the now-filled Washington City Canal , which allowed passage through the city to the Anacostia River from 1815 until the 1850s. The Chesapeake and Ohio Canal starts in Georgetown and
10164-519: The district, though the chairman of the House Subcommittee on District Appropriations, Ross A. Collins of Mississippi , justified cuts to funds for welfare and education for local residents by saying that "my constituents wouldn't stand for spending money on niggers."

10285-484: The eighteenth century. In Canada , there is a federal capital , while the ten provinces and three territories each have capital cities. The states of such countries as Mexico , Brazil (including the famous cities of Rio de Janeiro and São Paulo , capitals of their respective states), and Australia also each have capital cities. For example, the six state capitals of Australia are Adelaide , Brisbane , Hobart , Melbourne , Perth , and Sydney . In Australia,
10406-479: The female personification of the nation . The U.S. Constitution in 1789 called for the creation of a federal district under the exclusive jurisdiction of the U.S. Congress . As such, Washington, D.C., is not part of any state , and is not one itself. The Residence Act , adopted on July 16, 1790, approved the creation of the capital district along the Potomac River. The city was founded in 1791, and
10527-683: The first to use electrical wiring in its design. Notable contemporary residential buildings, restaurants, shops, and office buildings in the city include the Wharf on the Southwest Waterfront , Navy Yard along the Anacostia River , and CityCenterDC in Downtown . The Wharf has seen the construction of several high-rise office and residential buildings overlooking the Potomac River . Additionally, restaurants, bars, and shops have been opened at street level. Many of these buildings have
10648-401: The freezing mark (32 °F or 0 °C). On average, the first day with a minimum at or below freezing is November 18 and the last day is March 27. Washington, D.C., was a planned city , and many of the city's street grids were developed in that initial plan. In 1791, President George Washington commissioned Pierre Charles L'Enfant , a French-born military engineer and artist, to design
10769-545: The great crisis of Japanese invasion . National capitals were arguably less important as military objectives in other parts of the world, including the West, because of socioeconomic trends toward localized authority, a strategic modus operandi especially popular after the development of feudalism and reaffirmed by the development of democratic and capitalistic philosophies. In 1204, after the Latin Crusaders captured
10890-660: The intermeshing of their suburban zones, taking on some characteristics of a single, massive city: a megalopolis , a term he co-opted from an ancient Greek town of the same name that named itself out of aspirations to become the largest Greek city. The Northeast megalopolis includes many of the financial and political centers of influence in the United States , including the national capital of Washington, D.C. , and all or part of 12 states (from north to south): Maine , New Hampshire , Massachusetts , Rhode Island , Connecticut , New York , New Jersey , Pennsylvania , Delaware , Maryland , West Virginia , and Virginia . The region
11011-460: The land originally ceded by Virginia , including the city of Alexandria. In 1871, it created a single municipality for the remaining portion of the district. There have been several unsuccessful efforts to make the district into a state since the 1880s; a statehood bill passed the House of Representatives in 2021 but was not adopted by the U.S. Senate . To become law it would have to be passed by
11132-473: The megalopolitan area owned by national or international corporations have also appeared, such as BoltBus and Megabus . These ventures indicate not only the dual "independent nuclei"/"interlinked system" nature of the megalopolis, but also a broad public understanding of and capitalization on the concept. In 2007, Gottmann's "megalopolis" concept was largely supported by John Rennie Short , who authored an update to Gottmann's book, Liquid City: Megalopolis and
11253-543: The nation's largest industry associations, non-profit organizations, and think tanks , D.C. is known as a lobbying hub, with K Street as the industry center.

However, the constitution does not specify a location for
11495-493: The new capital. He enlisted the help of Isaac Roberdeau, Étienne Sulpice Hallet and Scottish surveyor Alexander Ralston to help lay out the city plan. The L'Enfant Plan featured broad streets and avenues radiating out from rectangles, providing room for open space and landscaping. L'Enfant was also provided a roll of maps by Thomas Jefferson depicting Frankfurt, Amsterdam, Strasbourg, Paris, Orleans, Bordeaux, Lyon, Marseille, Turin, and Milan. L'Enfant's design also envisioned
11616-551: The north and south sides of the National Mall, respectively, are home to many of Washington's iconic museums, including many Smithsonian Institution buildings and the National Archives Building . Washington hosts 177 foreign embassies ; these maintain nearly 300 buildings and more than 1,600 residential properties, many of which are on a section of Massachusetts Avenue informally known as Embassy Row . The architecture of Washington, D.C., varies greatly and

Most streets are set out in a grid pattern with east–west streets named with letters (e.g., C Street SW), north–south streets with numbers (e.g., 4th Street NW), and diagonal avenues, many of which are named after states . The City of Washington was bordered on the north by Boundary Street (renamed Florida Avenue in 1890); Rock Creek to the west, and
11979-541: The other hand, while the major cities of the Northeast megalopolis all are distinct, independent cities, they are closely linked by transportation and telecommunications. Neil Gustafson showed in 1961 that the vast majority of phone calls originating in the region terminate elsewhere in the region, and it is only a minority that are routed to elsewhere in the United States or abroad. In 2010 automobiles carried 80% of Boston-Washington corridor travel; intercity buses 8–9%; Amtrak 6%; and airlines 5%. Business ventures unique to
12100-569: The outskirts of major cities, such as Bethesda in Maryland (outside of Washington, D.C.) and Camden in New Jersey (outside of Philadelphia), may be clearly distinct areas with even their own downtowns . However, they tend to be independent of their host cities in few, if any, ways, still being considered suburbs or lesser cities that almost certainly would not have developed in the ways that they have without their host cities' presence. On
12221-535: The portion originally donated by Maryland. Confirming the fears of pro-slavery Alexandrians, the Compromise of 1850 outlawed the slave trade in the district, although not slavery itself. The outbreak of the American Civil War in 1861 led to the expansion of the federal government and notable growth in the city's population, including a large influx of freed slaves. President Abraham Lincoln signed
12342-466: The provincial level, a dynasty could easily be toppled with the fall of its capital. In the Three Kingdoms period, both Shu and Wu fell when their respective capitals of Chengdu and Jianye fell. The Ming dynasty relocated its capital from Nanjing to Beijing , where they could more effectively control the generals and troops guarding the borders from Mongols and Manchus . The Ming
12463-523: The region have sprung up that capitalize on the interconnectedness of the megalopolis, such as airline shuttle services that operate short flights between Boston and New York City and New York City and Washington, D.C. that leave every half-hour, Amtrak's Acela Express high-speed rail service from Washington to Boston, and the Chinatown bus lines , which offer economy transportation between the cities' Chinatowns and elsewhere. Other bus lines operating in
12584-537: The region in the early 17th century. The Nacotchtank , also called the Nacostines by Catholic missionaries , maintained settlements around the Anacostia River in present-day Washington, D.C.

The Northeast megalopolis is home to hundreds of colleges and universities, including several that rank among
12826-401: The rest of the strip. Additionally, the proximity to Europe, as well as the prominence of Ellis Island as an immigrant processing center, made New York City and cities nearby a "landing wharf for European immigrants," who represented an ever replenished supply of diversity of thought and determined workers. By contrast, the other major source of trans-oceanic immigrants was China , which
12947-424: The seat of government of a polity or of a subdivision. Deliberately planned and designed capitals include: These cities satisfy one or both of the following criteria: Some examples of the second situation (compromise locations) are: Changes in a nation's political regime sometimes result in the designation of a new capital. Akmola (renamed Astana in 1998) became the capital of Kazakhstan in 1997, following
13068-531: The south to Boston in the north. The region is not uniformly populated between the terminal cities, and there are regions nominally within the corridor yet located away from the main transit lines that have been bypassed by urbanization, such as the Quiet Corner in Connecticut. The region accounts for 20% of the U.S. gross domestic product . It is home to two of the world's largest stock exchanges,
13189-491: The statehood bill was introduced again in January 2023. The bill would have made D.C. into a state with one representative and two senators, with the name Washington, Douglas Commonwealth (thus keeping the same abbreviation Washington, D.C.). The legalities, reasons, and impact of statehood have been heavily debated in the 2020s. Washington, D.C., is located in the Mid-Atlantic region of the U.S. East Coast . The city has
13310-677: The term "capital cities" is regularly used to refer to those six state capitals plus the federal capital Canberra , and Darwin , the capital of the Northern Territory . Abu Dhabi is the capital city of the Emirate of Abu Dhabi and also of the United Arab Emirates overall.

In Federalist No. 43 , published January 23, 1788, James Madison argued that the new federal government would need authority over a national capital to provide for its own maintenance and safety. The Pennsylvania Mutiny of 1783 emphasized
13673-439: The violence. Many stores and other buildings were burned, and rebuilding from the riots was not completed until the late 1990s. In 1973, Congress enacted the District of Columbia Home Rule Act providing for an elected mayor and 13-member council for the district. In 1975, Walter Washington became the district's first elected and first black mayor. Since the 1980s, the D.C. statehood movement has grown in prominence. In 2016,

As of 2020, it contained more than 50 million people, about 17% of the U.S. population on less than 2% of the nation's land area, with a population density of about 1,000 people per square mile (390 people/km ), far more than
13915-538: The width of the adjacent street plus 20 feet (6.1 m). Despite popular belief, no law has ever limited buildings to the height of the United States Capitol or the 555-foot (169 m) Washington Monument , which remains the district's tallest structure. City leaders have cited the height restriction as a primary reason that the district has limited affordable housing and its metro area has suburban sprawl and traffic problems. Washington, D.C., still has
14036-748: The world's most elite universities, including Harvard and MIT , both in Cambridge, Massachusetts , Brown in Providence, Rhode Island , Yale in New Haven, Connecticut , Columbia in New York City, Princeton in Princeton, New Jersey , the University of Pennsylvania in Philadelphia , Johns Hopkins in Baltimore , and Georgetown in Washington, D.C.

The capital city attracts politically motivated people and those whose skills are needed for efficient administration of national or imperial governments, such as lawyers , political scientists , bankers , journalists , and public policy makers . Some of these cities are or were also religious centres , e.g. Constantinople (more than one religion), Rome / Vatican City (the Roman Catholic Church ), Jerusalem (more than one religion), Babylon, Moscow (the Russian Orthodox Church ), Belgrade (the Serbian Orthodox Church ), Paris, and Beijing. In some countries,
14278-632: Was destroyed when Li Zicheng took their seat of power, and this pattern repeats itself in Chinese history, until the fall of the traditional Confucian monarchy in the 20th century.

14399-497: Was farther from the U.S. West Coast than Europe was from the East, and whose ethnicity made them targets of racial discrimination , creating barriers to their seamless integration into American society. By 1950, the region held over one-fifth of the total U.S. population, with a density nearly 15 times that of the national average. The region has been home to the richest city in the nation for over 200 years: Hartford, Connecticut held
14520-402: Was made the nation's capital. According to Gottmann, capital cities "will tend to create for and around the seats of power a certain kind of built environment, singularly endowed, for instance, with monumentality, stressing status and ritual, a trait that will increase with duration." The transportation and telecommunications infrastructure that the capital city mandated also spilled over into
