Abaqa Khan
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 Derbent 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. He was then succeeded by his son Rukn-uddin Kurt II.
