It is called the District of Columbia because the U.S. Constitution created a special federal district—separate from any state—for the national capital, and that district was given the poetic national name “Columbia,” an old allegorical name for the United States derived from Christopher Columbus.

Quick origin story

  • The Constitution (Article I, Section 8) allowed Congress to establish a federal district up to 10 miles square to serve as the seat of government, so it wouldn’t be inside any one state or under state control.
  • In 1790, Congress created this federal territory along the Potomac River; that territory was called the “Territory of Columbia,” using “Columbia” as a symbolic, poetic name for the new nation, based on Columbus’s name.
  • The capital city inside that territory was named “Washington” to honor George Washington, so the full name became “Washington, District of Columbia,” or Washington, D.C.

Why “Columbia”?

In the late 18th and early 19th centuries, “Columbia” was a widely used poetic personification of the United States, similar to how “Britannia” personified Britain. It came from the Latinized form of Christopher Columbus’s surname and was used in place names, songs, and institutions (for example, Columbia University and the patriotic song “Hail, Columbia”). Using “Columbia” in the district’s name emphasized the idea that this capital area belonged to the entire country, not any single state.

Why “District”?

“District” signaled that this was a distinct federal jurisdiction, not a state or ordinary city. Legally, it was a federal district where Congress had direct authority, which is why residents historically lacked the same level of representation in Congress that states have. Over time, as the federal territory was reorganized (notably with the Organic Act of 1871) and the Virginia portion was retroceded, the name “District of Columbia” stuck as the formal designation for the remaining federal capital area.
