The New England 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 Maine, New Hampshire, Vermont, Massachusetts, Rhode Island and Connecticut.

The CommonwealthEdit

The Commonwealth is what is left of the pre-War state of Massachusetts. While traditionally called a commonwealth in and of itself before the Great War, Massachusetts was also part of the greater New England Commonwealth.

The region was spared much of the nuclear devastation of the Great War as the greater Boston area was only hit by one nuclear bomb, which missed and hit an area to the south. However, the radiation from the nuclear-strike zone still remains potent 200 years later, unlike many other areas across the post-war US. Despite this stroke of luck, the region still fell into general anarchy, and overall did not fare much better than the rest of the Wasteland.

Different factions would vie for control of the region, including multiple raider gangs and small settlements. The survivors of the Commonwealth Institute of Technology took shelter in the basements of the college buildings and would form The Institute, a technologically advanced and enigmatic faction. The failures of their technological pursuits would be thrown out in the wasteland, littering the region with Super-Mutants and Synths.

A militia band known as the Minuteman grew to prominence, defending the major settlement of Diamond City against a super mutant attack in 2180. Eventually, a unified government in the region was proposed- under the tentative name of the Commonwealth Provisional Government. Every settlement of influence was invited to talks discussing the idea but during the meeting, a synth killed every representative, destroying the Commonwealth Provisional Government. An underground movement was formed to combat the Institute, known as The Railroad, with the aim of liberating synths from Institute control.

Over time the influence of the Minutemen waned, due to setbacks such as losing their main headquarters, the Castle, and internal conflict. This culminated with the Quincy Massacre, where the last of the minutemen tried and failed to defend the settlement of Quincy, leading to the Minutemen's near extinction.

The Eastern Brotherhood of Steel would soon enter the region as well, upsetting the local power balance- having sent recon teams to scout the region, learning of the Institute, and finding them an affront to their ideology, coming in in-force, with a powerful airforce, claiming the Boston Airport for their own.
