The attacks on the Zabrak colonies across the Outer Rim by Mandalorian Neo-Crusaders were among the first major battles of the Mandalorian Wars fought during the Mandalorian invasion of the Galactic Republic in 3963 BBY.
The Galactic Republic, without support from the Jedi, had little success in the war's early campaigns. Several systems, including some of the Zabrak colonies, fell to the Mandalorian onslaught. In response to the Mandalorians' unprovoked aggression, many people on the Zabrak homeworld of Iridonia, including a gifted tech specialist named Bao-Dur, enlisted in the Republic military seeking vengeance.
