The last Minutemen general, Joe Becker, died in 2282, but who should serve as successor was never agreed upon. The overall faction was historically led by a general and individual contingents led by a colonel. The Minutemen continued in their goals of responding to requests for help from nearby settlements that were being attacked, lending their aid towards its defense. They maintained operations from this location until 2240, while under the leadership of General McGann, the headquarters were destroyed by a creature that emerged from the surrounding ocean. Meanwhile, the group established its headquarters at Fort Independence in South Boston, referring to it as 'the Castle.' The group including Ronnie Shaw established an armory within the facility, guarded by a sentry bot named Sarge. This effort was cut short when group members were murdered by the Institute's representative, a synth. The Minutemen then attempted to branch out to organize a provisional government with regional settlements.

The group first rose to prominence in 2180, when they defended Diamond City against a super mutant attack. A statue near the Old North Bridge commemorates the original group, standing where the first shots of the Revolutionary War were fired. Similar to the Minutemen of the Revolutionary era, the modern day group is focused on defending the people of Massachusetts, at a minute's notice. The Commonwealth Minutemen are a volunteer civilian defense militia, described as citizen soldiers banding together to protect themselves and their communities.
