Research on non-violent civil resistance has burgeoned in recent years. This field has much in common with the study of social movements, and yet there has been little cross-fertilization between these literatures. In this article, I review the historical development of non-violence studies from its Gandhian roots, through an emphasis on strategic non-violence, to current empirical research that has generated new insights into the strategic interactions between non-violent movements and their opponents, the effects of repression, the factors shaping movement outcomes, and cross-national tactical diffusion. I summarize key findings and implications for the field of social movements. I conclude by charting out new areas of inquiry that future researchers ought to explore.Recently, a growing number of movements have successfully used non-violent tactics and strategies. These movementsincluding the "velvet revolutions" in Eastern Europe, the "color revolutions" in former Communist regions, and the Arab Spring revoltshave energized the field of non-violence studies, also known as civil resistance studies. Although non-violence studies offer insights into social movements, these two fields are largely disconnected. Therefore, in this article, I will (i) cover the historical development of non-violence studies; (ii) summarize its main findings, briefly indicating how this complements social movement studies; and (iii) delineate areas of inquiry that future researchers ought to pursue.
What is non-violent civil resistance and why study it?A quick look at the non-violence literature reveals that many terms are used: people power, non-violent action, satyagraha, and unarmed insurrections. Although each has distinct connotations, scholars have used "civil resistance" as an umbrella term to cover many forms of non-violence. Adam Roberts defined civil resistance as [A] type of political action that relies on the use of non-violent methods. . .. It involves a range of widespread and sustained activities that challenge a particular power, force, policy, or regimehence the term 'resistance.' The adjective 'civil' in this context denotes that which pertains to a citizen or society, implying that a movement's goals are 'civil' in the sense of being widely shared in a society; and it denotes that the action concerned is non-military or non-violent in character (Roberts, 2009, p. 2).
