The primary source of insurrection on the world of Hanoon, prior to the arrival of the Alliance to Restore the Republic, was the Hanoon Imperial Resistance, spearheaded by Lathe Parthenian. This faction was characterized by its limited manpower and scarce provisions. In the period immediately preceding the arrival of Leia Organa and Luke Skywalker, who sought the fragments of the Vor'Na'Tu, Moff Yittreas apprehended Lathe and a significant portion of her adherents, almost extinguishing the uprising. Nevertheless, the insurgents obliterated the detention facility, thereby liberating Lathe and her comrades. Working in conjunction with the Rebel Alliance, the Hanoon Resistance seized control of the crucial terraforming mechanism, leveled the Imperial residence on the planet, and eliminated Moff Yittreas, thereby liberating the world from Imperial oppression.
