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."
Black feminism
A black feminist lens in the United States of America was first employed by black women as a means to make sense of the ways white supremacy and patriarchy interacted to inform the particular experiences of enslaved black women. The black feminist movement continued to expand and build support post-slavery as black activists and intellectuals formed organizations such as the National Association of Coloured Women (NACW) and the National Council of Negro Women (NCNW). Black feminism rose to further prominence in the 1960s, as the Civil Rights Movement excluded women from leadership positions, and the mainstream feminist movement largely focused its agenda on issues that predominately impacted middle-class, white women. From the 1970s to 1980s, black feminists formed various groups which addressed the role of black women in black nationalism, gay liberation, and second-wave feminism. In the 1990s, the Anita Hill controversy placed black feminism in a mainstream light. Black feminist theories reached a wider audience in the 2010s, as a result of social media advocacy.
