What is the capital of the United States?

The capital of the United States is Washington, D.C. This city was specifically chosen to serve as the nation's capital and is where the federal government is located, including the President's residence, Congress, and the Supreme Court. Washington, D.C. is significant not only as the center of American government but also as a historical and cultural hub, home to numerous national monuments, museums, and government buildings.

New York City, Los Angeles, and Chicago, while being major American cities, do not hold the status of the national capital. New York City was the first capital of the United States under the Articles of Confederation but was replaced by Washington, D.C. as part of a compromise that included the southern states' support for a federal district. Thus, Washington, D.C.'s role and status as the capital are essential aspects of its significance in the United States.
