Jedi–Zygerrian conflict

"For thousands of years, Zygerria supplied slave labor to the galaxy. We prospered. Our customers prospered! Then the Jedi came."

- Darts D'Nar

A war was waged by the Jedi Order against the Zygerrian Slave Empire to end their slaving operations after they were outlawed in Republic space. Their defeat left many Zygerrians such as Darts D'Nar and Atai Molec with a seething hatred of the Jedi.

Behind the scenes
The Databank entry on the Zygerrians does not make it clear whether the conflict was undertaken by the Jedi of the Old Republic or its successor.
