A Study Of The Dacheng Regime Between The Tow Han Dynasty

In the late years of Wang Mang's Xin dynasty,the social contradiction was intensified.With the help of the peasant uprising,there was a riot at all levels of society,including the local force's division by force.In the southwest region,Gongsun Shu was divided by using the name of "Fu Han" and the support of the local magnates.As Bashu land lies thousands of miles,rich products and solid population,it has a superior social economic base.North according to HanZhong,east to JiangLing,with the advantaged mountains and rivers as a barrier,Gungsun Shu set up Dacheng regime,established system and became one of the most powerful independent regime at the beginning of Donghan dynasty.At that time,"People miss han" ethos became the mainstream social consciousness.Compared the legitimacy of Liu Xiu Han's regime,in the disadvantage of public opinion,Gongsun Shu proved the legitimacy of Dacheng regime and won public support with prophetic-mixed theory.But the later historians most had a derogatory view at the legitimacy of Dacheng regime.During his reigon,Gongsun Shu adopted a series of measures to consolidate his power in political construction,economic reform and military expansion.The official system including bureaucratic establishment and the etiquette system was based on the Sangong system in the late years of Xihan dynasty.The economic reform included wasting copper coin and casting iron money.However,due to the lack of relevant literatures,the research on the reasons,currency system and site need more archaeological materials.According to the situation of the southwest geography,the two strategic expansion lines were also deployed.The east defend the Ganguan military checkpoint,float down the Yangtze river and occupy the Jiangling for the Jingxiang;the north guard the Nanzheng,out of Hanzhong for the Sanfu places.However Gongsun Shu was befeated in the north battle line and adopted a passive defense strategy in the late period.In the end,Gongsun Shu was killed and the regime was destroyed by Liu Xiu.The reason for its demise is mainly attributed to the failure of the military strategy.But it is also because of his political construction and economic reform.At the end of the Donghan dynasty,the Bashu area was ruled by Liu Yan,Liu Zhang,and Liu Bei.Throughout the locality separatist powers in tow Han dynasty,they all rose sharply with the social situation,had a similar expansion strategy:across Jingyi in east and out of Qinchuan in north,and had the same extinct fate.But they all failed to unification of the whole country.The most fundamental reason is the inherent weakness of the comprehensive national strength,such as geopolitics,the conflidct between the guest and master,the dominator's political accomplishment and the talent resource.
