What is the capital of the United States?

The capital of the United States is Washington, D.C. This city was established as the national capital in 1790 and has served as the political center of the country ever since. It is home to the federal government, including the President's residence at the White House, the legislative chambers of Congress, and the Supreme Court. Washington, D.C. was specifically chosen as a compromise location between the northern and southern states, and it is not part of any state, which allows it to serve as a neutral ground for the federal government. This unique status emphasizes its role as a central hub for national governance. The other cities listed, while significant in various capacities, are not the capital and do not hold the same political importance at the national level.
