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."
European Feminist Forum
The EFF had its origins in 2004, when several European feminists met in Amsterdam, and were worried that the promises of the United Nations Fourth World Conference on Women had not been met. Several groups became involved in the forum after receiving an invitation to join in December 2004. These groups included Mama Cash, Women in Development Europe (WIDE), European Women's Lobby, Network of East-West Women, the International Information Centre and Archives for the Women's Movement (IIAV) and others. These organizations and the individuals representing them began to plan the form of the EFF, and in 2006, created a steering committee and IIAV decided to host the forum.
