The '''Great War of Confederation''', beginning 975.[[M41]], was a large war fought between the [[Tau Empire]] and several [[Ork]] [[Waaagh!]]'s. Along with [[Hive Fleet Gorgon]], it was the first time the Tau Empire truly fought for its own survival, and its effects helped pave way for the [[Third Sphere of Expansion]].{{Fn|1}}
