The Onderon Civil War was a dynastic conflict during the First Jedi Purge that struck the planet Onderon in 3951 BBY. The war occurred when General Vaklu organized a confederation known as the Onderon separatists in Iziz that resisted Galactic Republic rule in the sector. The separatists were intent on overthrowing Queen Talia, loyal to the Republic, and having Onderon secede from the Galactic Republic.
