This article recovers the history of the transnational women's movement that arose during Portugal's colonial wars (1961-1974). This movement connected women in Portugal and its colonies and operated independently of the PCP, MPLA, PAIGC, and FRELIMO. Most research on women's activism in Portugal, Angola, Guinea-Bissau, Cabo Verde, and Mozambique begins with their relationships to the male-dominated organizations that operated within national frameworks. In contrast, by examining the international connections of these women's groups, this article illuminates their political activities outside national organizations led by men. It shows that women created transnational solidarity networks struggling against the Portuguese Estado Novo and the colonial wars and, in doing so, promoted their own emancipation.
