Langoonan rebellion

During their enslavement by the Hutt species the Langoonan species, whom were native to the planet Langoona in Hutt Space, unsucesfully rebelled against their masters. Prior to the rebellion the Langoonans had been considered a favored slave species by the Hutts but after their defeat they were stripped of technology and driven to the brink of extinction. The small population that did survive was maintained by the Hutts for use in safaris.

Behind the scenes
The Lagoonans rebellion was first mentioned in the 2009 reference book The Essential Atlas which was written by Daniel Wallace and Jason Fry. Neither the time frame or name of the rebellion are mentioned in the book.
