The Second Earth Alliance Civil War was a major conflict between two factions of the Earth Alliance, one loyal to the ideals of the Interstellar Alliance and the legacy of its founders, and another favoring a break with the Alliance. While several Earth nations and colonies continued to support the ISA five hundred years after its foundation, Politdivision believed that the ISA was restrictive and that Earth needed room to expand. For this reason, Politdivision Central intended to break away from the ISA.
