Transnational feminism
In the "Oxford Handbook of Transnational Feminist Movements", Valentine Moghadam says that "women have worked together across borders since at least the mid-1800s. (55)" What is now called first wave feminism started in the early twentieth century in the West with a focus on women's suffrage. 
During World War II, the United States government gave women jobs because the war had caused a national shortage of labor. After the war ended, Irene Tinker says (oxford transnational), these jobs were taken away but women were no longer satisfied going back to their previous gender roles. Starting in the 1960s in the United States, second wave feminism emerged, defined by women's organization around "equal right to education, employment, and equal pay for equal work, and on sexual and reproductive rights."
Míriam Martinho
The feminist movement in Brazil, became fairly active in 1975. After the II Congress of the Paulista Women there was a split between leftist leaders and feminists. At that time, feminists were supporting the concept of gender, rather than class, as a focus for political empowerment and equality. The schism resulted in the feminists moving forward on their own and a flurry of magazines and critical thought on feminism emerged. Many feminist organizations were founded each with specific themes: education, health, political empowerment, sexuality, violence, among others. Martinho was part of this movement, founding the first lesbian feminist group, "Grupo Lésbico-Feminista", in 1979. In 1981 the group disbanded and part of the members went on to form the "Grupo Ação Lésbica-Feminista" (GALF), the most active of whom were Martinho and Rosely Roth. In 1989, GALF reformed as an NGO called "Um Outro Olhar".
