Shams al-Din Isfahani

Shams al-Din Isfahani was a Persian vizier and military commander in medieval Anatolia. He served as deputy (na'eb) to Sultan Kaykhusraw II of the Seljuk Sultanate of Rum and as the commander-in-chief of his army. After the vesselage of the Sultanate to the Mongol Empire, he became deputy to the Mongol ruler Batu Khan (r. 1227–1255) in Anatolia. He later reached the apex of his power when he became the new vizier of the Sultanate of Rum, and its de facto ruler for a short period after Kaykhusraw II's death.
