The Atreides Empire was the term by which the Imperium was known when it was ruled by House Atreides. It was established when the Duke Paul Atreides successfully led a Fremen uprising on Arrakis against the Corrino Empire. One of the other Great Houses, House Harkonnen, was also destroyed in this uprising. The commencement of the Atreides Empire was marked by the moving of the imperial seat from Kaitain to Arrakis. The end of the Atreides Empire was marked by a traumatic bout of famine and migration across the uncharted universe in a diaspora known as The Scattering.
