League Civil War

The League Civil War was a war that occured way back in the Dark Times, before the League was properly established. Back then, the Members of the League refused to get on, and the Council Meetings were little more than petty squabbles. Even the renowned Face of Boe couldn't stop races like the Daleks and the Reapers from getting at each other.

Eventually, war broke out. For the duration of this time, the planets of the League became decimated, each and every one torn apart by war. Despite only having existed for a short time, (relatively speaking), it looked as if the League was going to fall.

Thousands upon thousands of Daleks, Reapers, Sith, Humans, Jedi, Cybermen, Elites, Brutes, Jackals, Flood, Protheans and even Hanar waged endless war against each other. The citizens of the Galaxy stirred, knowing that the outcome of the war would decide their fate. Several star systems broke away from the League altogether and founded the Galactic Council - races like the Mole Men, the Money Spiders and the Prowlers.

When all hope seemed lost, there was some degree of improvement. The Sith Empire was rebuilt as the Galactic Republic, and at the same time a Human-Cyberman alliance shattered the Dalek fleet in orbit around their home planet of Skaro and the Emperor was killed.

At this point the Hanar religion had been established and they agreed on a non-violence policy. Also, the Flood and the Reapers retreated into the Dark Space outside any Galaxy and this left only the Covenant as aggressors. The negotiations were short, but in the end the Covenant were cast out to the far reaches of the Galaxy beyond the reaches of the Council, the League or the New Republic. They would not return until they waged war against the Human Empire, 2500 years later.

At this point a severe reordering of the League was instigated. The various feuding alliances were disbanded and they were all reintergrated back into the League, except for three - the Covenant, the Cybermen and the Reapers.

Despite this, the League maintained its position as largest peacekeeping force in the Galaxy, and there was not another conflict in the Galaxy for another 5000 years.
