Abaqa Khan reigned from 1265-1282, the son of Hulegu and Oroqina Khatun, a Mongol Christian, was the second Il_Khan emperor in Persia.

During his reign, Abaqa, a devout Buddhist, attempted to convert the Muslims and harassing them mercilessly by promoting Nestorian and Buddhist interests ahead of the Muslims, by sending embassies to Pope Gregorio X and Eduardo I of England. During his harsh reign, many Muslims attempted to assassinate Abaqa.

At the time of Hulegu's, Abaqa, on his father's behalf, continued to fight with Berke Khan's forces until 1267, the time of Berke's death. He fought on his father's behalf after Hulegu, his father, died of illness in 1265. However, Barrak Khan tried to annex Iran in 1270 and thus starting war against Abaqa in the city of Herat. Abaqa successfully defended Iran, leaving his people victorious. Abaqa was succeeded by his Muslim brother Tekuder.
