The Second Imperial Civil War, also known as simply the Imperial Civil War and to the Galactic Alliance Core Fleet as the Second Rebellion, was a conflict that began with the end of the Sith–Imperial War in 130 ABY. It was the result of the Imperial victory at Caamas, in which part of the Galactic Alliance Defense Fleet refused to surrender; the Massacre at Ossus took place, in which several Jedi managed to survive; and, finally, the coup executed by Darth Krayt and the One Sith. This resulted in the fragmentation of the Fel Empire into two factions, one loyal to Fel and another loyal to the Dark Lord of the Sith. Over the next seven years, Krayt's empire was challenged by both Fel's Imperial supporters and the remnants of the Galactic Alliance under Admiral Stazi.
