This article deals with agents who produce, promote, and implement participation in Morocco, and it avoids any teleological approach without actors. It concentrates on a special period—the turn from the twentieth century to the twenty-first—before the institutionalization of processes, practices, and roles. In this context, it highlights the role of intermediaries who have contributed to the importation of participation in Morocco and made themselves the experts of it. Participation is viewed as a space of social and professional reclassification. The analysis sets out the necessary competencies to be an expert on participation: past professional experience, knowledge of grassroots organizations, academic knowledge, and a political past. The article links two stories that are necessary to understand these new social positions: that of roles that are in the process of being linked to an offer of participation from international organizations and that of the people who fill them.
