Shams al-Din
Shams al-Din Juvayni (; also spelled Joveyni) was a Persian statesman and member of the Juvayni family. He was an influential figure in early Ilkhanate politics, serving as "sahib-i divan" (vizier and minister of finance) under four Mongol Ilkhans−Hulagu, Abaqa, Tekuder and Arghun Khan. In 1284, Arghun accused Shams al-Din of having poisoned the Ilkhan Abaqa, who may actually died of the effects of alcoholism; Shams al-Din was duly executed and replaced as vizier by Buqa. A skillful political and military leader, Shams al-Din is also known to have patronized the arts. The musician Safi al-Din al-Urmawi was one of those he supported.
