The Three Allied Kingdoms existed during the Pre-Republic era and was situated in the Tion Cluster. This political entity comprised the three kingdoms of Jaminere, Cadinth, and Barseg, all found along the Cadinth Run, in addition to other worlds like Arcan IV, Corlax 4, and Lianna. Between 25,150 BBY and 25,130 BBY, Xer VIII, the Pirate King, launched a military offensive directed at the Three Allied Kingdoms. This resulted in the conquest of those planets and their incorporation into Xer's Empire.
