How do patterns of political leadership affect the trajectories of ethnic separatist movements? The main bodies of theoretical literature (primordialism, instrumentalism, socio-psychological approaches, rational-choice theory, and "social movement" theory) all demonstrate remarkable uniformity in how they analyze the effects of political leadership on the course of ethnic movements. These theoretical approaches focus almost exclusively on the emotional or material relationship between leaders and their ethnic followers. They fail to give sufficient attention to the effects of "patterns of political leadership" (defined as the political inter-relationships between state and ethnic elites, between ethnic elites, and between state elites) on the evolution of ethnic movements. This paper takes an incipient step to fill this void. I use the macrohistorical approach and a "most-similar-systems" research design to compare and contrast the effects of "patterns of political leadership" on the trajectories of several ethnic movements in India. This includes the ethnic insurgencies in Punjab, Kashmir, and Assam in the Northeast. The larger goal of this paper is to formulate the basis for an incipient theory or model of how "patterns of political leadership" affect the trajectory of separatist insurgencies in general. Thus, this paper has both substantive and theoretical implications. ..PAT.-Unpublished Manuscript [ABSTRACT FROM AUTHOR]
