In 22 BBY, the government of that world issued an eight thousand credit bounty on the head of Rotar Lopani.[2]
During the Clone Wars, it was a major backer of the Galactic Republiccredit. Attempting to undermine the Republic economy, the Separatists attacked the world many times, just as the Republic tried to undermine the Separatist economy by attacks on Mygeeto.[3]
The Rebels sent three X-wings from Red Squadron to feint an attack on the Circarpous system in order to gauge Imperial defenses. TIE Fighters fell for the bait and intercepted the Rebels near Circarpous IV. Despite being outnumbered the Rebel ships destroyed the Imperials before leaving. The Rebels' success helped create sympathy for the Rebellion in the Circarpous system. The mission was later recreated as a simulation to help new Rebel pilots learn to overcome the odds.
