Butlerian Jihad

As mankind spread throughout the known universe, technology advanced and eventually machines were made that would make decisions for people. This propelled the creators of these machines into a new technocratic class, effectively controlling the worlds of the common people. Mankind eventually rebelled against these machines and their creators in a nigh-religious war that sought to retake the thinking soul of mankind from the gods of machine logic. After two generations of violence, humanity took pause. Following this, their gods and rituals were looked upon in a different, perhaps even jaded, light. Both were largely seen to be guilty of using fear as a means of control. Hesitantly, the leaders of religions began meeting to exchange views, and a new, central religious precept was defined, that man may never be replaced by a machine.
