Ata-Malik Juvayni
Hulagu left 3,000 Mongol soldiers behind to rebuild Baghdad. Ata-Malik Juvayni was later appointed governor of Baghdad, Lower Mesopotamia, and Khuzistan after Guo Kan went back to the Yuan dynasty to assist Kublai's conquest over the Song dynasty. The Mongol Hulagu's Nestorian Christian wife, Dokuz Khatun, successfully interceded to spare the lives of Baghdad's Christian inhabitants. Hulagu offered the royal palace to the Nestorian Catholicos Mar Makikha, and ordered a cathedral to be built for him.
