Abaqa Khan
Abaqa Khan (February 1234 – 4 April 1282, , "paternal uncle", also transliterated Abaġa), was the second Mongol ruler ("Ilkhan") of the Ilkhanate. The son of Hulagu Khan and Lady Yesünčin. He was the grandson of Tolui and reigned from 1265 to 1282 and was succeeded by his brother Ahmed Tekuder. Much of Abaqa's 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.
