This article argues that the emergence and development of subaltern political process is a significant conflict dynamic found in the escalation of ethnic nationalist movements. These ethnie-defined modes of political participation are in turn an expression of the autonomous nature of ethnic nationalism, but occur ‘underneath’ and often antecedent to the organised violence and militancy which distracts most analyses of these conflicts. The article discusses this process of insurgent political mobilisation as a response to the structural paralysis of the post-colonial state, using the ethnic nationalist conflict in Indian Jammu and Kashmir as the central case study. In its discussion of this case, the article seeks to argue that the presence of such subaltern political process provides additional empirical evidence of the autonomous nature of ethnic nationalism, and its capacity to carve out alternative options for democratic action and popular participation.
