What is the capital of the United States?

The capital of the United States is Washington, D.C., which serves as the seat of the federal government. It was established as the capital in 1800 and designed specifically to be the nation's capital, located between the two states of Maryland and Virginia. Washington, D.C. houses important government buildings, including the White House, the U.S. Capitol, and the Supreme Court.

This choice reflects the city's central role in American politics and governance, distinguishing it from other major cities like New York City, Los Angeles, and Chicago, which, while significant in various aspects such as culture and economy, do not serve as the nation's capital.
