Ata-Malik Juvayni
Shams al-Din was also closely linked with the local vassal states of the Ilkhanids, such as the Kartids of Herat, the Qutlugh-Khanids of Kerman, the Salghurids of Fars, and the Hazaraspids of Luristan. He maintained Ilkhanid bureaucrats in each realm, and had an representative in charge of the rejuvenation of the Yazd area. Furthermore, he also increased the influence and authority of his family by giving them posts within the country; his eldest son Baha al-Din Muhammad was appointed governor of Persian Iraq, whilst another son of his, Sharaf al-Din Harun Juvayni, was appointed governor of Anatolia. Shams al-Din's older brother Ata-Malik Juvayni had already been given the governorship of Iraq in 1259 before the latters rise.
