The Galactic Republic achieved liberation of the planet Iridonia in 3963 BBY amidst the Mandalorian Wars. This action removed the Mandalorian Neo-Crusaders' dominance over the world. Following the Mandalorian invasion, the Republic Military, aided by Zabrak military forces, launched a counteroffensive, expelling the Mandalorians from Iridonia, although some Mandalorian influence persisted within Iridonian society.
