protests. In the mode of the Arab Spring, the color revolutions of the former Soviet Union, and the people power movement of the Philippines, such movements overcome the daunting impediments presented by autocrats, appeal to likeminded counterparts across society, and overwhelm the ability of regimes to maintain order. Conversely, in other settings, such as contemporary China, decentralized state structures provide an inhospitable environment for national-level protest, leading collective actors to opt for more local and parochial forms of contention. This outcome produces paradoxical situations, such as in the PRC, where protests are frequent but national-level mobilization and coordination is absent.
