Organizations of the Dune universe

Multiple organizations of the Dune universe dominate the political, religious, and social arena of the setting of Frank Herbert's Dune series of science fiction novels, and derivative works. Set tens of thousands of years in the future, the saga chronicles a civilization which has banned computers but has also developed advanced technology and mental and physical abilities through physical training, eugenics and the use of the drug melange.
