Shamanism and Buddhism were once the dominant religions among the ruling class of the Mongol khanates of Golden Horde and Ilkhanate, the two western khanates of the Mongol Empire. In the early days, the rulers of both khanates increasingly adopted Tibetan Buddhism, similar to the Yuan dynasty at that time. However, the Mongol rulers Ghazan of Ilkhanate and Uzbeg of Golden Horde converted to Islam in 1295 CE because of the Muslim Mongol emir Nawruz and in 1313 CE because of Sufi Bukharan sayyid and sheikh Ibn Abdul Hamid respectively. Their official favoring of Islam as the state religion coincided with a marked attempt to bring the regime closer to the non-Mongol majority of the regions they ruled. In Ilkhanate, Christian and Jewish subjects lost their equal status with Muslims and again had to pay the poll tax; Buddhists had the starker choice of conversion or expulsion. In Golden Horde, Buddhism and Shamanism among the Mongols were proscribed, and by 1315, Uzbeg had successfully Islamicized the Horde, killing Jochid princes and Buddhist lamas who opposed his religious policy and succession of the throne.
