For the Han Chinese, however, it was a humiliating reminder of Qing authority that challenged traditional Confucian values. The order triggered strong resistance in Jiangnan. In the ensuing unrest, some 100,000 Han were slaughtered. On 31 December 1650, Dorgon suddenly died during a hunting expedition, marking the start of the Shunzhi Emperor's personal rule. Because the emperor was only 12 years old at that time, most decisions were made on his behalf by his mother, Empress Dowager Xiaozhuang, who turned out to be a skilled political operator. Although his support had been essential to Shunzhi's ascent, Dorgon had centralised so much power in his hands as to become a direct threat to the throne. So much so that upon his death he was bestowed the extraordinary posthumous title of Emperor Yi (), the only instance in Qing history in which a Manchu "prince of the blood" () was so honored.

Kangxi Emperor's reign and consolidation The sixty-one year reign of the Kangxi Emperor was the longest of any emperor of China and marked the beginning of the "High Qing" era, the zenith of the dynasty's social, economic and military power. The early Manchu rulers established two foundations of legitimacy that help to explain
