District of Columbia

The District of Columbia, commonly known as Washington, D.C., is the capital city of the United States. It is a federally designated area created to serve as the nation's government center, not part of any state. Located along the Potomac River, it hosts important government buildings, including the White House and Congress. D.C. has its own local government, but Congress ultimately has authority over it. As a vibrant city, it offers cultural, historical, and political landmarks, making it a unique hub for national administration and diverse communities.
