The world of Iridonia, a planet, experienced an invasion by the Mandalorian Neo-Crusaders in the year 3963 BBY as part of the Mandalorian Wars. This event occurred after multiple attacks targeted colonies inhabited by the Zabrak species in that sector. The Mandalorians maintained control of the planet for a time, incorporating certain Zabrak natives into their forces, until the Republic carried out the liberation of Iridonia.
