« Pas de retour à nos maisons sans satisfaction de nos revendications ». Le Hirak du Rif en actes face au Makhzen
Published 2024-07-01“…In Morocco, while the protests led by the Hirak Rif Movement (2016-2017) were eventually stifled due to the scale of the repressive campaign, the various attempts to stop the movement have first helped to fuel the protest dynamic. Our main argument is that while the movement's activists employed initially (and above all) the most routine tactics of protest (such as demonstrations whose times and locations were publicly announced in advance), they progressively innovated tactically (through, for example, surprise demonstrations known as "chen-ten" and pot-banging protests), moved to new protest sites (such as the various districts of Al Hoceima and the beaches) and encouraged the involvement of heterogeneous protest profiles (many of whom are young and/or have a distant connection to the activist universe) ; these processes fostered the movement's continuity and gave it a disruptive character. …”
