List of Dune religions

The Religions of Dune are a key aspect of the fictional setting of the Dune universe created by Frank Herbert. Many of the names of religions mentioned in the novels indicate they are blends of current belief systems, some syncretic.

According to Appendix II: The Religion of Dune in the 1965 novel Dune, after the Butlerian Jihad, the Bene Gesserit composed the Azhar Book, a "bibliographic marvel that preserves the great secrets of the most ancient faiths". Soon after, a group made up of the leaders of many religions (calling itself the Commission of Ecumenical Translators) created the Orange Catholic Bible, the key religious text of the Dune universe, which "contains elements of most ancient religions".

Buddislam

The term for those religions derived from a syncretic fusion of denominations of Buddhism and Islam. The connection of the Zensunni with Buddislam suggests the latter arose during the Third Islamic Movement associated with the Maometh Saari (see below under Third Islam).
