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."
Feminist views on sexuality
Lesbian feminism is a cultural movement and political perspective, most influential in the 1970s and early 1980s (primarily in North America and Western Europe), that encourages women to direct their energies toward other women rather than men, and often advocates lesbianism as the logical result of feminism. Some key thinkers and activists are Charlotte Bunch, Rita Mae Brown, Adrienne Rich, Audre Lorde, Marilyn Frye, Mary Daly, Sheila Jeffreys and Monique Wittig (although the latter is more commonly associated with the emergence of queer theory). Lesbian feminism came together in the early 1970s out of dissatisfaction with second-wave feminism and the gay liberation movement.
