Carthag

Carthag was the capital of the planet Arrakis under the rule of House Harkonnen.

Upon the change of fief ordered by the Padishah Emperor Shaddam IV, House Atreides took control of Arrakis in 10,191AG. Under the Atreides leader, the Duke Leto, the capital moved to the city of Arrakeen, which was approximately two hundred kilometres south west of Carthag.

Of the two cities, Carthag was larger, newer and more densely populated. Duke Leto had assessed that Arrakeen would be easier to defend if attacked, and thus made it the planet's capital. Moreover, Leto had theorised that, because Carthag was more densely populated, it was likely to have a greater number of Harkonnen agents that could potentially subvert Atreides rule.

During Siege of Arrakeen, Harkonnens also operated cleansing in Carthag and every stationed Atreides trooper was slain.
