Sonam Gyatso (Tibetan: བསོད་ནམས་རྒྱ་མཚོ་ Wylie: bsod nams rgya mtsho ZWPY: Soinam Gyaco) (1543–1588) was the first officially recognized Dalai Lama, although the title was retrospectively given to his two predecessors. According to Sumpa Khenpo, the great Gelug scholar, he also studied some Nyingmapa tantric doctrines. When one of Tibet's kings, who had been supported by the Kagyupa, died in 1564, Sonam Gyatso presided over his funeral. His political power, and that of the Gelugpas, became dominant in Tibet by the 1570s.
