Phagpa developed the priest-patron concept that characterized Tibeto-Mongolian relations from that point forward.[42][43] With the support of Kublai Khan, Phagpa established himself and his sect as the preeminent political power in Tibet. Through their influence with the Mongol rulers, Tibetan lamas gained considerable influence in various Mongol clans, not only with Kublai, but, for example, also with the Il-Khanids. [citation needed]
