This chapter introduces Argentina’s Black movement and situates it within discussions of Black movements in Latin America and social movements theory more broadly. I introduce evidence that the movement has made progress in combating historical erasure and racism and show that despite societal denial, activists mobilize collective emotions to raise awareness, increase participation, and access state resources. The book argues that emotions, both at the societal and interpersonal levels, play a crucial role in the efficacy of transnational Black social movements in spaces of invisibility. Focusing on Argentina’s understudied Black movement, I employ critical race theory and Black feminist perspectives to examine racialization processes, challenge myths of homogeneous Whiteness, and highlight Afrodescendants’ marginalization in Argentina. Additionally, I show that this study contributes to understanding emotions in social movements by analyzing emotional opportunity structures and the role of emotions in mobilization, particularly within the context of Black feminist activism.
