Abaqa Khan
Shams-uddin Muhammad succeeded his father in 1245, joined Sali Noyan in an invasion of India in the following year, and met the Sufi Saint Baha-ud-din Zakariya at Multan in 1247–8. Later he visited the Mongol Great Khan Möngke Khan (1248–1257), who placed under his sway Greater Khorasan (present Afghanistan) and possibly region up to the Indus. In 1263–4, after having subdued Sistan, he visited Hulagu Khan, and three years later his successor Abaqa Khan, whom he accompanied in his campaign against Darband and Baku. He again visited Abaqa Khan, accompanied by Shams-uddin the "Sahib Diwan", in 1276–7, and this time the former good opinion of the Mongol sovereign in respect to him seems to have been changed to suspicion, which led to his death, for he was poisoned in January 1278, by means of a water-melon given to him while he was in the bath at Tabriz. Abaqa Khan even caused his body to be buried in chains at Jam in Khorasan.
