The Butlerian Jihad, also called the Great Revolt, was a crusade against computers, thinking machines, and conscious robots that raged from 201 B. G. to 108 B. G.
As humanity expanded across the universe, machines began making decisions for people, creating a technocratic class that controlled common worlds. Humans rebelled in a near-religious war to reclaim humanity's thinking soul from "gods of machine logic." After two generations of violence, the Orange Catholic Bible established the commandment: "Thou shalt not make a machine in the likeness of a human mind." All intelligent machines were destroyed, causing severe technological regression. This gap led to the creation of the mentat order, Bene Gesserit, and Spacing Guild.
Non-thinking machines remained in use, while fringe worlds like Ix and Tleilax developed alternative technologies. The Jihad's legacy included a feudal galactic order under House Corrino and a renewed belief in human spiritual divinity.
