The Ascension of House Atreides can be traced to the marriage of Paul Atreides to Irulan Corrino after the Fremen defeat of the Sardaukar on the Plains of Arrakeen. Irulan Corrino was the eldest daughter of Shaddam IV. From that time through the death of Leto Atreides II, approximately 3,500 years later, the Atreides Empire dominated the Known Universe.
