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."
History of feminism
"Second-wave feminism" identifies a period of feminist activity from the early 1960s through the late 1980s that saw cultural and political inequalities as inextricably linked. The movement encouraged women to understand aspects of their personal lives as deeply politicized and reflective of a sexist power structure. As first-wave feminists focused on absolute rights such as suffrage, second-wave feminists focused on other cultural equality issues, such as ending discrimination.
