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."
Socialist feminism
The Chicago Women's Liberation Union, known colloquially as CWLU, was formed in 1969 after a founding conference in Palatine, Illinois. Naomi Weisstein, Vivian Rothstein, Heather Booth, and Ruth Surgal were among the founders of it. The main goal of the organization was to end gender inequality and sexism, which the CWLU defined as "the systematic keeping down of women for the benefit of people in power". The purpose statement of the organization expressed that "Changing women's position in society isn't going to be easy. It's going to require changes in expectations, jobs, child care, and education. It's going to change the distribution of power over the rest of us to all people sharing power and sharing in the decisions that affect our lives." The CWLU spent almost a decade organizing to challenge both sexism and class oppression. The group is best known for the 1972 pamphlet "Socialist Feminism: A Strategy for the Women's Movement". Nationally circulated, the publication is believed to be the first to use the term socialist feminism.
