What sets a single bout of state repression apart from a longer trajectory of political violence? Why does state repression of protesters sometimes result in discrete events of violence while, in other cases, it spurs larger cascades of political violence such as politicide, genocide, or civil war? This book introduces a new framework for state repression and its relationship to different forms of civil resistance. It argues that state repression in the modern era of history is an empirical phenomenon that has been marked by singularity. Through taking the law of coercive responsiveness as a starting point, this book reveals that when political status quos are challenged by civilians, states do respond in law-like ways, but the impact that state repression has on social change is more heterogeneous than previously considered.
