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. This city was specifically chosen for its location and its role as a neutral ground, facilitating representation from all states. Established as the capital in 1800, Washington, D.C. is home to the three branches of government: the Executive (the President), the Legislative (Congress), and the Judicial (the Supreme Court). It also hosts numerous national monuments, museums, and government institutions, making it a vital center for political activity and national heritage. The other cities mentioned, such as New York City, Los Angeles, and Chicago, hold significant cultural and economic importance but are not the capital of the nation.
