The ISC War of Pacification was a conflict that spanned the late 23rd century in the Alpha and Beta Quadrants that pit the Interstellar Concordium Pacification Army against the major powers of the two quadrants. (RIS Bouteina, Star Trek: False Vacuum, Star Trek: Unity (fan film series))


The Organians contacted the Interstellar Concordium in 2294, in an attempt to pacify the galaxy. The ISC entered the campaign expecting an easy victory, due to their higher morals and their rapid movement of large fleets, as well as advanced technology. Though well prepared, the native states resisted the ISC's attempts at enforcing harmony. (TOS video game: Starfleet Command II: Empires at War)

First phase[]

In 2294, the Interstellar Concordium earned its first victories against the Lyran Starfleet and the Hydran Royal Navy, including the Battle of Thuban. (Star Trek: False Vacuum: "Structural Unemployment")

Grand Alliance counter-attack[]

In 2298, Lyran forces from the Iron Fang County, as well as Hydran, Klingon and Federation forces, attacked the Grave of Thoughts, resulting in a large loss of life, ships and in the loss of prison camps in the First Battle at the Grave of Thoughts.

Operation Tyr was the final battle of the ISC War of Pacification, which resulted in the War Crime Trials on the ISC leadership.
