What is the capital of the United States?

The capital of the United States is Washington D.C. This city has been the seat of the federal government since its establishment following the American Revolution. It was chosen as the capital due to its strategic location along the Potomac River, making it accessible and central to the original thirteen states. Washington D.C. is home to significant government buildings, including the White House, the Capitol, and the Supreme Court, which further emphasizes its role as the center of U.S. political activity.

The other locations listed, such as New York, Philadelphia, and Los Angeles, while historically significant and populous cities, do not serve as the capital of the United States. New York was the first capital under the Constitution, but the capital was moved to Washington D.C. in 1800. Philadelphia served as the temporary capital while Washington D.C. was being built, but it is not the current capital. Los Angeles, while significant as a cultural and economic hub, has never been the capital of the United States. Therefore, Washington D.C. is recognized as the capital due to its established government functions and historical importance.
