Kangxi Emperor

The Kangxi Emperor came to the throne as a child and ruled for sixty-one years, one of the longest reigns in Chinese history. He crushed the Revolt of the Three Feudatories, brought Taiwan under Qing control, and pushed back Russian expansion in the north through the Treaty of Nerchinsk. He patronised scholarship, sponsored a famous dictionary, and employed Jesuit advisers at court. His consolidation of Manchu rule over the Han majority set up the long stability and territorial reach of the high Qing.
