Yongzheng Emperor (Shizong of Qing)
Also called: Shizong of Qing, Yinzhen
Fifth Qing emperor (r. 1722–1735), who strengthened imperial power through the Grand Council and extended the merged land-and-poll tax across the empire
Yinzhen, fourth son of the Kangxi Emperor, was made Prince Yong. He took the throne on his father’s death in 1722, but the succession was so contested that rumours spread that he had altered the will, and he imprisoned or killed the brothers who had been his rivals. Hence he devised the secret succession system, writing the heir’s name in advance and hiding it behind the “Upright and Bright” plaque in the Palace of Heavenly Purity. A tireless ruler who read and annotated countless memorials late into the night, he died suddenly in 1735.
