Qiangqujianzan, a very eminent person throughout Tibetan history had assumed office as the 10th head of Wanhu (ten thousand household) of Tibet in year 1322. After that, he had defeated Caiba in year 1348 and in year 1354, he occupied Sakya Monastery and replaced Sakya authorities. Then, he outcome with a new government named Pazhu Regime and controlled over most parts of Tibet. Moreover, he also obtained a title “Dasitu” as well as an official seal from Emperor Shun of Yuan Dynasty which enabled him to govern Tibet officially. Anyway, the lack of religious disciplines and monks’ corruption had result different sects of Buddhism to gradually lose their appeal to the public and the support from people. Upon this time, Tsongkhapa who advocated the strict observation of the disciplines and religious reform had appeared in the Tibetan history. Therefore, he successfully obtained great support from the Pazhu Government. In year 1409, a meeting on religious affairs which involved over 10,000 monks from various parts of Tibet took place. The event was funded by Pazhu Government and the main contact was Tsongkhapa with no doubt. After that, he established Ganden Monastery close to Lhasa in which marked the founding of the strictly disciplined Gelupa sec (also called Yellow Sect). Pazhu Regime which ruled Tibet for 264 years from 1354 to 1618 had 12 generations of kings.
