The analysis of the biographical consequences of activism is still insufficiently explored, especially in two directions. First, regarding the impact of activism on the different "life spheres" (family, private and professional) in which fit the individuals. The point is indeed to analyze together these different spheres whose permanent entanglement contributes to (re)direct political trajectories in varying time frames. Then, we propose to consider this first aspect in the perspective of a revolutionary commitment by linking it to the issue of political repression. What then are the implications of radical commitment and repression on the different life spheres and on the conversion dynamics (professional, political) of the activists? The proposed paper will attempt to provide some elements of this perspective through the case of illegal student organizations of the Turkish radical left since the 1970s and their members, who confronted repression before and after the 1980 military coup.
