What is the Capital of the United States?

The capital of the United States is Washington, D.C. because it was established as the capital in 1790 through the Residence Act. The location was chosen as a compromise between the northern and southern states, and it was designed by French architect Pierre Charles L'Enfant. The district was specifically created to ensure that no single state had too much influence over the federal government. Today, Washington, D.C. serves as the political center of the country, housing the White House, Congress, and numerous governmental institutions.
