As one of the most influential CCP campaigns that dramatically transformed the Chinese pre-revolutionary society, the early 1950s land reform has not been fully explored in the case of China's ethnic periphery. This article sheds light on the CCP's land reform and its impact on China's ethnic frontier by examining the official policies, implementation, and the reactions of the southern Muslim community in Yunnan between 1949 and 1958. Drawing on county government work team reports and the Party's land reform policy and evaluation records, it argues that although southern Yunnan Muslims were able to selectively internalize some Communist secular ideologies to cope with social and political changes that land reform brought about, the inconsistency between the Party's freedom of religion policy on paper and its local implementation failed to mitigate the ideological discord between Maoist revolutionaries’ atheist worldview and Muslim villagers’ religiosity. This jeopardized the possibility of reconciliation between the class-struggle-focused radical state and the community life of its religious subjects.
