The Eastern Commonwealth was one of the thirteen commonwealths of the pre-War United States. Created in 1969,[1] it was comprised of the former states of West Virginia, Delaware, Pennsylvania, New Jersey and New York.

Former PennsylvaniaEdit

The PittEdit

The post-War ruins of Pittsburgh are the basis of the Fallout 3 add-on The Pitt. Ruled by slavers, it is plagued by trogs, humans who degenerated due to the hazards produced by the city's three irradiated rivers over the decades.


Philly, once reminisced by Abraham Washington, was the post-War ruins of the city of Philadelphia. He sent an expedition there to recover the Liberty Bell, to bring back and display at the Capitol Preservation Society.[2]


A town mentioned by Everett. The Pitt raiders go out on raids in the town, and is overrun by trogs.

Former West VirginiaEdit


Appalachia is a vast swathe of West Virginia, which was also known pre-War as the Appalachian Territory. It is divided into six environmentally-distinct regions: Ash Heap, Cranberry Bog, Savage Divide, the Forest, the Mire, and Toxic Valley. As most of Appalachia was not a major strategic target, the Forest and Savage Divide made it through the Great War mostly intact apart from radiation contaminating the watershed, however, the other four regions have since been subsumed by heavily mutated flora and fauna or hazardous air and weather conditions. Appalachia was ravaged by a plague that wiped out practically all human survivors by 2102 when the residents of Vault 76 emerged to begin reconstruction.

Known locationsEdit


The Eastern Commonwealth appears in the Fallout 3 add-on The Pitt and Fallout 76. It is also mentioned in Fallout 3 and its add-ons Point Lookout and Mothership Zeta. It is also mentioned in the Fallout: New Vegas add-on Dead Money, Fallout 4 (as well as a cameo appearance of the Statue of Liberty in the Atomic Command game), and the Fallout Bible.
