The Kingdom of Jaminere existed during the Pre-Republic era, situated inside the Tion Cluster. This kingdom formed an alliance with the Kingdoms of Cadinth and Barseg, resulting in the formation of the Three Allied Kingdoms. Between 25,150 BBY and 25,130 BBY, Xer VIII, the Pirate King, launched a military operation against these kingdoms, which culminated in his victory over the Kingdom of Jaminere at the Battle of Jaminere. Subsequently, the worlds of the Three Allied Kingdoms were overtaken and incorporated into Xer's Empire.
