Massacre of the Commonwealth Provisional Government

The Massacre of the Commonwealth Provisional Government was a major event in the Commonwealth, when the Institute brutally slaughtered the Commonwealth Provisional Government, killing every representative present at the talks.

Interestingly, the Institute appears to have suppressed knowledge of the incident. The official records mention it as an attempt to create a stable Commonwealth government gone awry.

Appearances
The Massacre of the Commonwealth Provisional Government is mentioned only in Fallout 4.
