House Atreides

A fictional noble family from Frank Herbert's Dune novels. One of the great houses of the Imperium. This noble house hailing from the water planet of Caladan employs unlikely methods in its struggle to secure the spice of Arrakis: noble spirit, just ways and unfailing virtue. Ruling its homeworld Caladan for generations with justice and generosity, House Atreides has perfected a form of government that results in a well-organized society and a spiritually satisfied people. Little wonder that Caladan is the lush, prosperous paradise that it is.

House Atreides is ruled by a duke. At first in the Dune novel the Duke is Leto Atreides. He married the Bene Gesserit acolyte Jessica, who produced for him the son Paul Atreides.

Paul Atreides is the main character during the first novels. He fights with the Fremen in the war on Arrakis and finally becomes both the Fremen Messiah and Emperor of the known universe.

As Paul Atreides is lost in the desert eight years later, his sister Alia inherit his title as the Duke of Atreides and as Emperor.
