Also in 1618, the Tsangpa King, Karma Puntsok Namgyal, whose Mongol patron was Choghtu Khong Tayiji of the Khalkha Mongols, attacked the Gelugpa in Lhasa to avenge an earlier snub and established two military bases there to control the monasteries and the city. This caused Sonam Rabten who became the 5th Dalai Lama's "changdzo" or manager, to seek more active Mongol patronage and military assistance for the Gelugpa while the Fifth was still a boy. So, in 1620, Mongol troops allied to the Gelugpa who had camped outside Lhasa suddenly attacked and destroyed the two Tsangpa camps and drove them out of Lhasa, enabling the Dalai Lama to be brought out of hiding and publicly enthroned there in 1622.
