Outline of Washington, D.C.

The City of Washington was originally a separate municipality within the Territory of Columbia until the District of Columbia Organic Act of 1871 effectively merged the City and the Territory into a single entity. It is for this reason that everything within its boundaries is legally the District of Columbia.
