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."
Radical feminism
Within groups such as New York Radical Women (1967–1969 (no relation to the present-day socialist feminist organization Radical Women), which Ellen Willis characterized as "the first women's liberation group in New York City", a radical feminist ideology began to emerge that declared that "the personal is political" and "sisterhood is powerful", formulations that arose from these consciousness-raising sessions. This call to women's activism was coined by Kathie Sarachild in the 1960s. New York Radical Women fell apart in early 1969 in what came to be known as the "politico-feminist split" with the "politicos" seeing capitalism as the source of women's oppression, while the "feminists" saw male supremacy as "a set of material, institutionalized relations, not just bad attitudes". The feminist side of the split, which soon began referring to itself as "radical feminists", soon constituted the basis of a new organization, Redstockings. At the same time, Ti-Grace Atkinson led "a radical split-off from NOW", which became known as The Feminists. A third major stance would be articulated by the New York Radical Feminists, founded later in 1969 by Shulamith Firestone (who broke from the Redstockings) and Anne Koedt.
