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 movements and ideologies
Black feminism argues that sexism, class oppression, and racism are inextricably bound together. Forms of feminism that strive to overcome sexism and class oppression but ignore race can discriminate against many people, including women, through racial bias. The National Black Feminist Organization (NBFO) was founded in 1973 by Florynce Kennedy, Margaret Sloan, and Doris Wright, and according to Wright it, "more than any other organization in the century launched a frontal assault on sexism and racism". The NBFO also helped inspire the founding of the Boston-based organization the Combahee River Collective in 1974 which not only led the way for crucial antiracist activism in Boston through the decade, but also provided a blueprint for Black feminism that still stands a quarter of a century later. Combahee member Barbara Smith’s definition of feminism that still remains a model today states that, "feminism is the political theory and practice to free all women: women of color, working-class women, poor women, physically challenged women, lesbians, old women, as well as white economically privileged heterosexual women. Anything less than this is not feminism, but merely female self-aggrandizement." The Combahee River Collective argued in 1974 that the liberation of black women entails freedom for all people, since it would require the end of racism, sexism, and class oppression. One of the theories that evolved out of this movement was Alice Walker's womanism. It emerged after the early feminist movements that were led specifically by white women, were largely white middle-class movements, and had generally ignored oppression based on racism and classism. Alice Walker and other womanists pointed out that black women experienced a different and more intense kind of oppression from that of white women.
