Abaqa Khan

Abaqa Khan , also Abaga , or Abagha Khan, was the second Mongol ruler of the Persian Ilkhanate. The son of Hulagu Khan and Yesuncin Khatun, he reigned from 1265 to 1282 and was succeeded by his brother Tekuder Khan. Much of Abaqas reign was consumed with civil wars in the Mongol Empire, such as those between the Ilkhanate and the northern khanate of the Golden Horde. Abaqa also engaged in unsuccessful attempts at military invasion of Syria, including the Second Battle of Homs.

Abaqa was born in Mongolia in February 1234, son of Ilkhanate founder Hulagu Khan. His stepmother was Hulagus Keraite princess bride, Doquz Khatun. Doquz, a devout Nestorian Christian, was regarded as a spiritual leader of the Mongols, who were generally tolerant of many religions. Abaqa himself was marginally Buddhist, though he was also very sympathetic to Christianity due to his mothers influence. A favored son of Hulagu, he was made governor of Turkestan.
