The Federation Civil War was the common name given to a conflict which erupted within the United Federation of Planets in 2372 and ended in 2374. (Star Trek: Pendragon)

Note that this conflict took place in the Pendragon timeline and its branches, not in the prime universe, or the "Dominion War timeline."


Blockade of Sector 001Edit

Second Battle of Wolf 359Edit



Borg interludeEdit

In late 2373, the Borg sent a single Borg cube to assimilate Earth. The attack was defeated but at significant cost. Admiral Leyton's grip on Sector 001 and the surrounding space was weakened due to losses his forces suffered. Patriot forces also managed to gain valuable intelligence about the defenses of the Sol system due to their last minute involvement in support Leyton's forces as the cube neared Earth.


Operation ReturnEdit

Operation Return was the codename for the Starfleet plan to retake Earth and Sector 001 from Admiral James Leyton that brought the Federation Civil War to an end. During the battle Leyton's fleets were engaged with Starfleet forces, several away teams from both sides met. Captain Picard and Admiral Edward Jellico sent a joint message to both fleets, calling for a cease fire. Afterwards Jellico surrendered the Leytonite forces to Admiral William Ross aboard Spacedock.


Immediately after the war's end, Admiral Alynna Nechayev used her political influence to steer the Federation toward an isolationist stance, focused on rebuilding and "cleaning house," while Starfleet's diplomatic and exploratory missions were curtailed. This ideology would become known as the "Nechayev doctrine," and held sway over the UFP for several years. The return of the USS Voyager from the Delta Quadrant in 2378 was seen as the beginning of a turnaround from this viewpoint.
