"The project aims to abductively produce a framework of the process of rebel groups consolidation by inductively building it from the Syrian civil war and deductively test it on events from the Libyan civil war. The goal is to build a framework that travels across cases with considerable generalizability. Immersed in historical institutionalism and adopting process tracing to approach this issue will help explore the process of consolidation. I aim to describe the events of consolidation, identify their causes and conditions, and clarify on the process components. For that, the inquiry covers the sequence and pace of events and their causal mechanisms to comprehensively capture the phenomenon. The research outcomes theoretically bring a better understanding to groups' behavior and collective action; while practically lending more clarity and predictability to civil war dynamics, war ending, and post-war reconstruction.
