The introduction traces how this collective intervention emerged from Rio de Janeiro, where scholar-activists have generated globally relevant tools for organizing and concepts for alternative governance shaped by five centuries of transnational exchanges and comobilizations, not just with the North and across the Americas but with the African continent, including the regions of today’s Angola and Congo. Rio has served as a transfer hub and site of innovation for collective resistance. Rio’s progressive concepts and resistance models fought their way onto the stage of history as they confronted and exposed the social origins, ideologies, and weak-points of emergent hard-right political regimes. Rio’s social movements, media influencers, community organizers, cultural figures, student organizations, Afro-Brazilian religious groupings, and a broad front of new feminist, ecology, Black, queer, and labor mobilizations did not just provide resistance; they engineered a series of triumphs and articulated new methods of being and of being political.
