Zhejiang, a crucial region in Southern Ming's resistance against the Qing, saw complex and violent socio-political transformations in the two decades of the Ming-Qing transition. This paper does not focus on political regimes of the Southern Ming; but on Zhejiang as a region of resistance. It studies the various battles, social crises, political alliances and rivalries of that period, and demonstrates both the leadership that the Zhejiang elites exercised and the weaknesses that they exhibited within the Southern Ming regimes. It shows that the demise of the Southern Ming regimes in Zhejiang was largely the result of the internal rivalries of the elites.
