アルタン・ハーン
Following the advice of his nephew Hutuhtai Secen Hongtaiji, Altan Khan of Tumet invited the head of the Gelug school Sonam Gyatso to his domain. Upon their meeting in 1577, Altan Khan recognized Sonam Gyatso lama as a reincarnation of Phagpa lama. Sonam Gyatso, in turn, recognized Altan as a reincarnation of Kublai Khan. Thus, Altan added legitimacy to the title "khan" that he had assumed, while Sonam Gyatso received support for the supremacy he sought over the Tibetan sangha. Since this meeting, the heads of the Gelugpa school became known as Dalai Lamas. Altan Khan also bestowed the title Ochirdara (Очирдар, from Sanskr. Vajradhara) to Sonam Gyatso.
