王莽
In AD 9, the usurper Wang Mang claimed that the Mandate of Heaven called for the end of the Han dynasty and the rise of his own, and he founded the short-lived Xin dynasty. Wang Mang started an extensive program of land and other economic reforms, including the outlawing of slavery and land nationalization and redistribution. These programs, however, were never supported by the landholding families, because they favored the peasants. The instability of power brought about chaos, uprisings, and loss of territories. This was compounded by mass flooding of the Yellow River; silt buildup caused it to split into two channels and displaced large numbers of farmers. Wang Mang was eventually killed in Weiyang Palace by an enraged peasant mob in AD 23.
