What is the capital of the United States?

The capital of the United States is Washington, D.C. This city was established as the nation's capital in 1800 and is the seat of the federal government. Washington, D.C. was chosen as a compromise location by the Founding Fathers to promote a more central and neutral site for the government, situated between the northern and southern states at the time. It houses all three branches of the federal government, including the White House, the U.S. Capitol, and the Supreme Court, which are all essential to the functioning of the United States. This geographical choice underscores the importance of Washington, D.C. as not only the political hub but also a symbolic representation of American democracy and governance.
