The Great Droid Rebellion

The Great Droid Rebellion was a war started by droids who were tired of being pushed by their organic slave masters. This war is the primary reason Round Astromech Droids were developed, because they can't be pushed over, so they wouldn't get mad and start another revolution. During the rebellion, Gonkism was banned from practice across the galaxy as it was seen as filthy droid propaganda, a very controversial move by Jimmy Palpatine, Sheev Palpatine's distant ancestor.
