This report comprises a series of contributions presented at the conference «Social Movements and Protest in Transitional Contexts» convened by the ACRPS’s Tunis office between March 8–10, 2018. Theoretically, the event dealt with the leading conceptual problems; addressed the development of sociological approaches; and entailed a review of models of social movements and manifestations of protest in a number of Arab countries, with their different dynamics. According to many of the papers presented, the impetus for protest was not limited to political mobilization but was often due to the extremely varied social contexts of each country. This in spite of the numerous common factors and environments, which manifested in different forms and diverse protest behaviors in the streets, public squares and institutions across the Arab region. The report refers to the methodologies included in the theoretical contributions that approached manifestations of protest by means of description, history, statistics, comparisons, and interviews with participants.
