Great Unification War

The Great Unification War was a war against the Old Republic, starting in 3777 BBY and lasting until 3759 BBY. The name "Great Unification" is stating that all the galaxy's powers had come together to wage war against the Republic. The Sith, Mandalorians, Exchange and Hutt forces all combined into one and threatened to crush the Republic.

The war would end in 3759 BBY, with the defeat of the Dark Lord of the Sith and the current Mandalore at the hands of Xeno Halthorn and Filose Naj respectively. Following this war, a somewhat quiet period came to the Republic, the only skirmishes being a small rebellion led by Dorn Atun and a Sith uprising many years later.
