Washington, D.C. is the capital city of the United States. It is also known as the District of Columbia, or simply D.C.. This special area is not part of any state. It sits on the Potomac River, bordering Virginia and Maryland. The city was named after George Washington, the first U.S. president. The "Columbia" part comes from a poetic name for the United States.

The U.S. Constitution created a special federal district. This district would be under the direct control of the U.S. Congress. This means Washington, D.C., is not a state itself. It is also not part of any other state. In 1790, a law called the Residence Act approved creating this capital district. It was built along the Potomac River. The city was founded in 1791. The U.S. capital moved from Philadelphia to Washington, D.C., in 1800.

A French engineer named Pierre Charles L'Enfant designed the city in 1791. It has wide streets and avenues that spread out from central points. The city is divided into four sections called quadrants. These sections meet at the Capitol Building. Washington, D.C., has many neighborhoods.

In 2020, about 689,545 people lived in Washington, D.C. During the workweek, over one million people are in the city. This is because many people commute from nearby Maryland and Virginia. The larger Washington metropolitan area includes parts of these states. It is the seventh-largest metropolitan area in the country. About 6.3 million people lived there in 2023.

Since 1973, Washington, D.C., has been led by a locally elected mayor. It also has a 13-member council. However, Congress can still change local laws. People in Washington, D.C., do not have voting representatives in Congress. They elect one delegate who can speak but not vote in the House of Representatives. Since 1961, D.C. residents can vote for the U.S. president.

Washington, D.C., is a very important world capital. It is home to the U.S. federal government. You can find famous buildings here like the White House, the Capitol, and the Supreme Court Building. The city also has many national monuments and museums. Most of these are on or near the National Mall. Examples include the Jefferson Memorial and the Lincoln Memorial. Many countries have their embassies here. Important international groups like the World Bank also have their main offices in D.C.

History of Washington, D.C.

Early History and Founding

When Europeans first arrived in the early 1600s, Algonquian-speaking tribes lived around the Potomac River. These included the Piscataway people. Conflicts with European settlers and other tribes caused the Piscataway people to move.

Before Washington, D.C., nine other cities served as capitals for the U.S. government. New York City was the first capital under the Constitution. Then Philadelphia was the capital from 1790 to 1800. In 1783, Congress decided to look for a new capital location. They wanted it near the Delaware or Potomac Rivers.

James Madison wrote in 1788 that the new federal government needed its own capital. This would help it stay safe and run smoothly. An event in 1783, where soldiers protested, showed that the government needed to be independent.

The U.S. Constitution allows for a special "District" to be the seat of government. This district could be up to ten miles square. It would be given by states and accepted by Congress. The Constitution did not say where the capital should be. In 1790, leaders agreed to pay states' Revolutionary War debts. In return, the new capital would be in the Southern United States.

On July 9, 1790, Congress passed the Residence Act. This law approved a national capital on the Potomac River. President George Washington chose the exact spot. He signed the law on July 16, 1790. The district was formed from land given by Maryland and Virginia. It was a square, ten miles on each side.

Two towns, Georgetown and Alexandria, were already in this area. In 1791 and 1792, a team surveyed the district's borders. This team included Andrew Ellicott and Benjamin Banneker. They placed stone markers at each mile. Many of these stones are still there.

The new federal city was built on the north bank of the Potomac River. It was east of Georgetown. On September 9, 1791, the city was named Washington. This honored President Washington. The district was named Columbia. This was a poetic name for the United States. Congress met there for the first time on November 17, 1800.

In 1801, Congress passed a law that officially organized the district. It placed the whole area under federal control. People in the district were no longer considered residents of Maryland or Virginia. This meant they lost their representation in Congress.

Burning During the War of 1812

On August 24, 1814, during the War of 1812, British forces attacked Washington, D.C. They burned government buildings. This included the United States Capitol, the Treasury Building, and the White House. This event is known as the burning of Washington. A storm forced the British to leave after only 24 hours. Most buildings were quickly fixed. The Capitol, still being built, was not finished until 1868.

Changes and Growth

In the 1830s, the southern part of the district, Alexandria, faced economic problems. Its citizens asked Virginia to take back the land. This process is called retrocession. In 1846, Congress agreed to return the land Virginia had given. This left the district with only the land from Maryland.

The American Civil War began in 1861. The federal government grew, and many freed slaves moved to the city. President Abraham Lincoln signed the Compensated Emancipation Act in 1862. This ended slavery in the district. About 3,100 enslaved people became free. In 1868, African American men in the district gained the right to vote in local elections.

By 1870, the district's population had grown to nearly 132,000 people. But the city still lacked paved roads and good sanitation. Some in Congress wanted to move the capital further west. However, President Ulysses S. Grant said no.

In 1871, Congress combined the cities of Washington and Georgetown. They also got rid of Washington County. This created one single government for the whole District of Columbia. This made the "city of Washington" the same as the "District of Columbia."

Modern Era and Home Rule

In 1961, the Twenty-third Amendment was passed. This gave Washington, D.C., three votes in the Electoral College for presidential elections. But residents still could not vote for members of Congress.

After Martin Luther King Jr. was assassinated in 1968, there were riots in the city. Many buildings were burned. Rebuilding took many years.

In 1973, Congress passed the District of Columbia Home Rule Act. This law allowed D.C. to elect its own mayor and council. In 1975, Walter Washington became the first elected mayor. He was also the first black mayor.

Since the 1980s, there have been efforts to make D.C. a state. In 2016, D.C. voters strongly supported statehood. A bill to make D.C. a state passed the House of Representatives in 2021. However, it did not pass in the Senate.

Geography and Climate

Washington, D.C., has a lot of parkland. About 19% of the city is parks. This is the second-highest amount among big U.S. cities. The National Park Service manages most of the parkland. Rock Creek Park is a large urban forest. It is one of the country's oldest national parks. It has many plants and animals like raccoons, deer, and owls.

Weather in Washington, D.C.

Washington has a humid subtropical climate. This means summers are hot and humid. The average temperature in July is about 80°F. The humidity can make it feel even hotter. Thunderstorms are common in summer.

Winters are cool to cold. Snow happens, but the amount varies. Big snowstorms, called nor'easters, can affect the East Coast. The biggest snowfall recorded was 28 inches in 1922.

Hurricanes sometimes affect the area in late summer or early fall. But they are usually weaker by the time they reach Washington. Flooding from the Potomac River can cause damage in Georgetown. Rain falls throughout the year.

City Layout and Buildings

How the City Was Designed

Washington, D.C., was a planned city. Pierre Charles L'Enfant designed the capital in 1791. His plan included wide streets and avenues. These streets spread out from central points. He also planned for open spaces and gardens. The National Mall was part of his vision. It was inspired by famous gardens in France.

By the early 1900s, parts of L'Enfant's plan were not followed. Congress created a committee to improve the city. The McMillan Plan in 1901 helped restore L'Enfant's original design. It added more parks and cleared slums.

There is a law about building heights in D.C. The Height of Buildings Act of 1910 limits how tall buildings can be. This is why the city's skyline is low and spread out. This law helps keep the views of monuments clear.

Washington, D.C., is divided into four sections: Northwest (NW), Northeast (NE), Southeast (SE), and Southwest (SW). These sections meet at the U.S. Capitol. All street names include the section abbreviation. Streets are mostly in a grid pattern. East-west streets have letters, and north-south streets have numbers. Diagonal avenues are often named after states.

Some streets are very famous. Pennsylvania Avenue connects the White House to the Capitol. K Street is known for its many lobbying offices. Constitution Avenue and Independence Avenue are on either side of the National Mall. They have many museums. Washington, D.C., has 177 foreign embassies. Many are on Massachusetts Avenue, also known as "Embassy Row."

Federal Voting Rights

Congress has always controlled the federal district. For a long time, people living there could not vote in federal elections. This changed in 1961. The 23rd Amendment gave Washington, D.C., three votes in presidential elections. This is the same number of votes as the smallest state.

However, Washington, D.C., is not a state. So, its residents do not have voting representatives in Congress. They elect a delegate to the House of Representatives. This delegate can speak and propose laws but cannot vote on the House floor. D.C. has no official representation in the United States Senate.

Even though they don't have full representation, D.C. residents pay all federal taxes. In 2012, they paid more federal taxes than people in 19 states. Many people in D.C. want full voting rights. Their license plates say, "End Taxation Without Representation." Polls show that most Americans think D.C. should have voting representation.

Some people are against D.C. having full voting rights. They say the Founding Fathers did not intend for the district to have a vote. They also say making D.C. a state would give too much power to one city.

In 2021, a bill to make D.C. a state passed the House of Representatives. But it did not pass in the Senate. Another idea is to return the district's land to Maryland. This would give D.C. residents normal state representation.

Education in D.C.
