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."
History of feminism
Modern feminism in Germany began during the Wilhelmine period (1888–1918) with feminists pressuring a range of traditional institutions, from universities to government, to open their doors to women. The organized German women's movement is widely attributed to writer and feminist Louise Otto-Peters (1819–1895). This movement culminated in women's suffrage in 1919. Later waves of feminists continued to ask for legal and social equality in public and family life. Alice Schwarzer is the most prominent contemporary German feminist.
