The Livien League existed as a sovereign state in the Tion Cluster during the Pre-Republic era. This state encompassed several worlds, including Amarin, Jhantoria, Kanaver, and Livien, with its capital planet situated on Desevro. During the period known as the Cronese Sweeps, the Pirate King Xer VIII attempted an invasion of the League, but it resisted his efforts successfully, standing alone as the only region within the Tion Cluster to remain outside of his dominion. Following Xer's abdication, Xim the Despot achieved victory over the League in the Battle of Jhantoria, leading to its capitulation; unusually for the Despot, he then integrated it into his empire in a largely peaceful manner. Xim achieved the first unification of the cluster; Xer's Empire and the Livien League were combined to form Xim's Empire.
Following the disintegration of Xim's Empire after his defeat by the Hutts in the Third Battle of Vontor, the planets that once constituted the Livien League were incorporated into the Honorable Union of Desevro and Tion. Subsequently, the planets located around Livien along the Desevran Trace came to be known collectively as the Livien Worlds.
