Washington, D.C., formally the District of Columbia and commonly referred to as "Washington", "the District", or simply "D.C.", is the capital of the United States. It was called Washington, in honor of the country’s first president, George Washington. The larger federal area would be named the District of Columbia. Columbia had become another name for the United States, one that was used by poets and other writers. The name came from Christopher Columbus, the explorer who sailed from Europe across the Atlantic Ocean to the Western Hemisphere. Today, Washington, D.C. is known to those who live in the area as the District. But if you want to write to us, our address is Washington, D.C.
