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."
Antifeminism
Founded in the U.S. by Phyllis Schlafly in 1972, Stop ERA, now known as "Eagle Forum", lobbied successfully to block the passage of the Equal Rights Amendment in the U.S. It was also Schlafly who forged links between Stop ERA and other conservative organizations, as well as single-issue groups against abortion, pornography, gun control, and unions. By integrating Stop ERA with the thus-dubbed "new right", she was able to leverage a wider range of technological, organizational and political resources, successfully targeting pro-feminist candidates for defeat.
