In 1636 the Manchus proclaimed their dynasty as the Qing dynasty and by 1644 they had completed their conquest of China under the prince regent Dorgon. The following year their forces approached Amdo on northern Tibet, causing the Oirat and Khoshut Mongols there to submit in 1647 and send tribute. In 1648, after quelling a rebellion of Tibetans of Kansu-Xining, the Qing invited the Fifth Dalai Lama to visit their court at Beijing since they wished to engender Tibetan influence in their dealings with the Mongols. The Qing were aware the Dalai Lama had extraordinary influence with the Mongols and saw relations with the Dalai Lama as a means to facilitate submission of the Khalka Mongols, traditional patrons of the Karma Kagyu sect. Similarly, since the Tibetan Gelugpa were keen to revive a priest-patron relationship with the dominant power in China and Inner Asia, the Qing invitation was accepted. After five years of complex diplomatic negotiations about whether the emperor or his representatives should meet the Dalai Lama inside or outside the Great Wall, when the meeting would be astrologically favourable, how it would be conducted and so on, it eventually took place in Beijing in 1653. The Shunzhi Emperor was then 16 years old, having in the meantime ascended the throne in 1650 after the death of Dorgon. For the Qing, although the Dalai Lama was not required to kowtow to the emperor, who rose from his throne and advanced 30 feet to meet him, the significance of the visit was that of nominal political submission by the Dalai Lama since Inner Asian heads of state did not travel to meet each other but sent envoys. For Tibetan Buddhist historians however it was interpreted as the start of an era of independent rule of the Dalai Lamas, and of Qing patronage alongside that of the Mongols.
