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."
First-wave feminism
The first women's movement was led by the "Dansk Kvindesamfund" ("Danish Women's Society"), founded in 1871. Line Luplau was one of the most notable woman in this era. Tagea Brandt was also part of this movement, and in her honor was established the Tagea Brandt Rejselegat or Travel Scholarship for women. The Dansk Kvindesamfund's efforts as a leading group of women for women led to the existence of the revised Danish constitution of 1915, giving women the right to vote and the provision of equal opportunity laws during the 1920s, which influenced the present-day legislative measures to grant women access to education, work, marital rights and other obligations.
