Wang Anshi
As the young emperor's regent, Grand Empress Dowager Gao appointed conservatives such as Sima Guang as Chancellor, who halted the New Policies set forth by Wang Anshi before dying in 1086. Emperor Zhezong was powerless and it was not until Grand Empress Dowager Gao's death in 1093 that the emperor was able to reinstate Wang Anshi's reforms and reduce the late Sima Guang's influence.
