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."
Social history of the United Kingdom (1945–present)
The feminist movement drew inspiration primarily from the United States, and from the experience of left-wing British women experiencing discrimination by male activists. Efforts to form a national movement in the mid-1970s foundered on a bitter split between the (predominantly heterosexual) socialists, and the (predominantly lesbian) radicals. The most visible spokesperson was Germaine Greer, whose "The Female Eunuch" (1970) called on women to rebel against marriage and instead live in heterosexual communes. Paul Addison concludes that," in popular culture, feminism was generally treated as a bit of a joke."
