Despite the central government's efforts in reducing fiscal burdens on peasants through fiscal reforms in the early 2000s, collective petitions in rural China remain. Complementary to the arbitrary and weak government explanations of state–society conflict, this article reveals the role of village cadres as activists in collective petition. Drawn from extensive fieldwork, I argue that by reducing local government revenues and recentralizing fiscal autonomy to the county level, central fiscal reforms have unintentionally induced a new force of resistance: village cadres. Being disenfranchised from previous privileges, village cadres are now allies rather than adversaries of peasant petitions. This article advances existing literature on China's contentious politics in two ways. First, it recognizes a new group of activists whose savoir-faire improves peasant knowledge of the state capacity in containing state–society conflict. Second, it proposes a dynamic understanding of contentious politics by highlighting the shifting boundaries between the state and society.
