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."
Latin American and Caribbean Feminist Encuentros
The First "Encuentro" was held in Bogotá in 1981 with 200 feminists and representing fifty NGOs from Argentina, Brazil, Chile, Colombia, Curaçao, Dominican Republic, Ecuador, Panama, Peru, Puerto Rico, and Venezuela. At this foundational meeting it was important for the women to discuss how they would define feminism. On the one hand were groups dismissing "feministas" as elites with no understanding of the political and social reality of middle- and lower-class women, and on the other hand, there were "políticas" or political militants, who were seen as radical leftists intent on continuing the revolutionary upheavals from which the various countries had so recently emerged. Feminists argued that they were not focused on obtaining "practical" (feminine) goals, but rather wanted relevant, "strategic" (feminist) focus. The militants stressed that the only way to reach all women was with "leftist party organizing and revolutionary mobilization".
