Overall, Mongols were highly tolerant of most religions, and typically sponsored several at the same time. Many Mongols had been proselytized by Nestorian Christians since about the 7th century,[3] and some tribes’ primary religion was Nestorian. In the time of Genghis Khan, his sons took Christian wives of the Kerait clan, and under the rule of Genghis Khan’s grandson, Möngke, the primary religious influence was Christian.
