Massacre of the CPG

The Massacre of the CPG was an incident that took place in the Commonwealth.

Background
Multiple settlements sent representatives to a meeting to discuss the terms of forming a Commonwealth Provisional Government, including the Commonwealth Minutemen.

According to Nick Valentine, the meeting was interrupted by the arrival of an Institute synth, who proceeded to attack and kill all of the representatives, and all negotiations ceased. For four years, the Institute was also a part of this process, but the project fell apart due to political infighting, and the violence was the result.

Appearances
The Massacre of the CPG is mentioned only in Fallout 4.
