Duan Zhengming
Duan Zhengming (posthumous name Baoding) was the 14th ruler of the Dali Kingdom. In 1081, the regent Gao Zhisheng forced Duan Zhengming's predecessor, Duan Shouhui, to abdicate and replaced him with Duan Zhengming. In 1094, Gao Shengtai, Gao Zhisheng's son, forced Duan Zhengming to relinquish the throne to him and renamed the Dali Kingdom to "Dazhong Kingdom". Gao Shengtai ruled briefly until his death in 1096, after which the throne was returned to the Duan family – Duan Zhengming's younger brother, Duan Zhengchun, became the new ruler and restored the kingdom's former name.
