The dissertation proposes an investigation into freedom and decolonization projects led by black women between the years 1989 and 1997 in South Africa and 1983 and 1989 in Brazil. The study addresses these projects as expressions of aspirations, strategies of struggle and resistance, which aimed to achieve rights and constitutional commitments. Furthermore, it is understood that through the investigation, listening, and understanding of struggles against power relations, policies of emancipation can be achieved, to the extent that the localized and sensitive knowledge of the marginalized subject provides a privileged epistemic perspective. In the first part, the work will address the theoretical framework and research fundamentals, while in a second part it will focus on identifying movements, women activists, and actions carried out both in the Brazilian and South African contexts. In the third part, the constitutional achievements obtained through the actions and strategies undertaken by black women in their respective contexts will be analyzed. The ultimate goal is to verify the possibility of establishing a dialogue between the experiences of black Brazilian and South African women in this specific period. Is it possible to identify an Atlantic constituent culture through the actions of black Brazilian and South African women, in their respective historical processes in search of a democratic constitutional structure? Within the scope of this question, it is hoped not only to reaffirm the protagonism of their narratives and trajectories but also to build a South-South bridge. Afro-diasporic thought, especially Amefrican thought, provides the epistemic-methodological foundations of this investigation.
