Since the late eighties, the Moroccan Left has been experiencing a profound ideological and political crisis exacerbated by the co-optation of the traditional socialist parties of the country. Starting from the nineties, numerous new forces tried to emerge as the new leading leftist front, although with little success. However, the events of 2011 in the Arab region played a crucial role in the revitalisation of the new Moroccan Left, today mostly represented by the Fédération de la Gauche Démocratique (FGD) and Annahj Addimocrati. The article investigates the interplay between the 20 February Movement (20FM) and these new socialist forces and it strengthens the idea that behind the 20FM and the establishment of a new non-governmental left lie the very same political and socio-economic reasons. Indeed, in 2011 the leftists attempted to emerge as leading forces side by side the 20FM, but due to their balkanization and internal divisions they were not able to form a united front and seize the opportunity to carry out their fight against the regime. Nevertheless, the political engagement of the 20FM stressed the importance of a new strong leftist-opposition front in the country and the 2011 protests eventually prompted the socialists to start a process of rapprochement aimed at overcoming the divisions of the past years.
