ABSTRACT
In this contribution, after some general comments on the different religions adopted by the uyghurs from the eighth to fourteenth centuries, I will argue that Tibetan buddhism in the thirteenth and fourteenth centuries had a strong influence in the Turfan region even though this was also the period of Islamization. The uyghur kingdom became part of the mongol empire after the uyghur king, the Idukkut, surrendered at the beginning of the thirteenth century. as a mark of respect a mongol princess was given to him in marriage and he was regarded as the fifth son of genghis khan.
