Columbia Commonwealth

The Columbia Commonwealth was one of the thirteen commonwealths of the pre-War United States. Created in 1969, it was comprised of the former states of Maryland and Virginia, as well as the District of Columbia.

Capital Wasteland
The Capital Wasteland spans much of the District of Columbia, as well as portions of both Maryland to the north and Virginia to the south. It is having power struggles between Brotherhood of the area, the Enclave survivors, and the super mutants. Vice and crime are rampant in the area, with raider clans, mercenary bands, and creatures pillaging any and all things that move.

Point Lookout
Another portion of Maryland, this time south of the Capital Wasteland proper, is available in the DLC content Point Lookout. Swamplands and swampfolk abominations are abundant, and while certain areas weren't directly hit by the bombs, the land and inhabitants are still being affected by radiation and disease, carried downstream from irradiated areas.
