The success of protest groups: Multivariate analyses

This paper reviews earlier research and presents new analytical findings regarding the outcomes of social movements. Using the resource mobilization/management approach, empirical propositions that seek to explain protest group success or failure are tested. Based upon data gathered from a sample of 53 US protest groups, the causal models explained the majority of the variance in degree of success between these groups. Our findings indicate that protest groups which threaten to replace or destroy established groups are usually unsuccessful, and those having many strong alliances tend to be more successful than groups fighting alone. The use of violence does not greatly aid the prediction of group outcome because of the unpredictable, ambivalent reaction to violence by established groups.
