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, primarily due to its strategic location along the Potomac River, which allowed for easier access and a compromise between the northern and southern states. Washington, D.C. was specifically created to serve as the seat of government, housing the nation’s executive, legislative, and judicial branches, including the White House, the Capitol, and the Supreme Court.

The selection of Washington, D.C. reflects the founding fathers' intention to separate the capital from the influence of any single state and ensures that it serves as a neutral ground. The other choices represent major U.S. cities, but they do not serve as the federal government’s seat. New York City was actually the first capital of the United States under the Articles of Confederation but was later replaced by Washington, D.C. Los Angeles and Chicago, while significant urban centers, are not designated as the capital and thus do not fulfill the role that Washington, D.C. does in terms of national governance and political significance.
