Nothing much is known about its history. While House Corrino originated from Salusa Secundus in 1487 AG, the Golden Lion Throne was moved there by Leto I of the House of Alman Corrino. When House Atreides wrested the Empire from the Corrinos in 10,193 AG the Imperial Capital moved from Kaitain to Arrakis, where it remained until the death of Leto Atreides II approximately 3,500 years later.
