Jules Falquet looks at the complexity of identities, loyalties and the interests of everyone in social movements. The book Imbrication. Femmes, race et classe dans les mouvements sociaux published in February 2020 by Éditions du Croquant, presents the history of guerrilla (Salvador), Indian-peasant (Zapatista movement in Mexico) or Black (Brazil, Dominican Republic, USA) struggles, as well as the women’s, feminist and lesbian movements of the continent: the women of the Americas and the Caribbean offer us an exceptional mirror to better understand “intersectionality” at a time of a profusion of struggles, sometimes confusing . Starting from the daily life of these movements in order to reach a veritable "science of the oppressed", this book is aimed at an inquisitive public as well as activists and the world of research.
