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
Black Lives Matter is an activist movement that was initially formed by Opal Tometti, Alicia Garza, and Patrisse Kahn-Cullors as a hashtag to campaign against racism and police brutality against African Americans in the United States of America. This has contributed to a revitalization and re-examining of the Black Feminist movement. While the deaths of black men played a major part in the Black Lives Matter movement, Rekia Boyd, Michelle Cusseaux, Tanisha Anderson, Shelly Frey, Yvette Smith, Eleanor Bumpurs, and others are women who were also killed or assaulted by police officers. This has been viewed as a Black Feminist Movement first, rather than as a part of the larger feminist movement. While Black Lives Matter has been critiqued for not always centering the ways that black women are subject to police brutality, it has since been better about incorporating the interlocking systems of oppression that disadvantage black women in particular.
