What is the capital of the United States?

The capital of the United States is Washington D.C. This city was established as the capital in 1800 and serves as the political hub of the nation. It is the location of important government institutions, including the White House, the U.S. Capitol, and the Supreme Court, as well as numerous national monuments and museums. Washington D.C. was specifically chosen as the capital to serve as a neutral ground between the northern and southern states during the early years of the country.

Understanding the significance of Washington D.C. as the capital is essential, as it reflects the nation's governance and political history. The other cities listed, while important in their own right, do not hold the status of the capital. New York City, Los Angeles, and Chicago are major urban centers in the U.S. but do not serve as the seat of the federal government.
