The Commonwealth

''This article is about a place mentioned in Fallout 3. For the pre-War United States 13 commonwealths, see United States.''

The  is what is left of the pre-War state of Massachusetts. While traditionally a Commonwealth in itself, before the Great War Massachusetts was also part of the New England Commonwealth. Most of it is a war-ravaged quagmire of violence and despair like much of the rest of the former United States (and perhaps the rest of the world), but it is also where the mysterious Institute is located.

Organizations
The Institute is likely the descendant of the Massachussets Institute of Technology. Little is known about Institute other than that the scientists working in the sealed environment of the institute possesses highly advanced technology and technological skills. The Institute has created true AI and is capable of creating convincing androids.

Another organization active in the Commonwealth, the Railroad, functions in direct opposition to the Institute, as their goal is to free sentient androids from their creators.

Harkness, Dr. Zimmer and Armitage are from the Commonwealth.

Appearances
The  is only mentioned in Fallout 3.
