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."
Second-wave feminism
Though it is widely accepted that the movement lasted from the 1960s into the early 1980s, the exact years of the movement are more difficult to pinpoint and are often disputed. The movement is usually believed to have begun in 1963, when Betty Friedan published "The Feminine Mystique", and President John F. Kennedy's Presidential Commission on the Status of Women released its report on gender inequality.
The administration of President Kennedy made women's rights a key issue of the New Frontier, and named women (such as Esther Peterson) to many high-ranking posts in his administration. Kennedy also established a Presidential Commission on the Status of Women, chaired by Eleanor Roosevelt and comprising cabinet officials (including Peterson and Attorney General Robert F. Kennedy), senators, representatives, businesspeople, psychologists, sociologists, professors, activists, and public servants. The report recommended changing this inequality by providing paid maternity leave, greater access to education, and help with child care to women.
