Multiple organizations of the Dune universe dominate the political, religious, and social arena of the fictional 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. Specialized groups of individuals have aligned themselves in organizations focusing on specific abilities, technology and goals. Herbert's concepts of human evolution and technology have been analyzed and deconstructed in at least one book, The Science of Dune (2008). His originating 1965 novel Dune is popularly considered one of the greatest science fiction novels of all time, and is frequently cited as the best-selling science fiction novel in history.Dune and its five sequels by Herbert explore the complex and multilayered interactions of politics, religion, ecology and technology, among other themes.

We've a three-point civilization: the Imperial Household balanced against the Federated Great Houses of the Landsraad, and between them, the Guild with its damnable monopoly on interstellar transport.

As Frank Herbert's Dune (1965) begins, the known universe is ruled by Shaddam IV, the 81st Padishah Emperor of House Corrino, whose power is secured by his control of the brutally efficient military force known as the Imperial Sardaukar. One balance to Imperial power is the assembly of noble houses called the Landsraad, which enforces the Great Convention's ban on the use of atomics against human targets. Though the power of the Corrinos is unrivaled by any individual House, they are in constant competition with each other for political power and stakes in the omnipresent CHOAM company, a directorship which controls the wealth of the entire Old Empire. The third primary power in the universe is the Spacing Guild, which monopolizes interstellar travel and banking through its proprietary use of melange-mutated Guild Navigators to "fold space."
