Intra-Jihadist Conflict and Cooperation: Islamic State–Khorasan Province and the Taliban in Afghanistan

The proliferation of jihadist groups raises intriguing questions about their internal relationship. Drawing on Resource Mobilization Theory we explore this question by examining the relationship between the Taliban and the local incarnations of the Islamic State of Iraq and Syrian (ISIS) in Afghanistan. We conceive the Taliban and ISIS as parts of a broader “jihadist movement industry” that is simultaneously united and divided by the logic of their embeddedness in the movement. While most existing research emphasizes intra-jihadist conflict or rivalry, we found that the relationship between the two groups goes through cyclical shifts, vacillating between conflict and cooperation.
