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 lesbianism
Lesbian feminism, which was most influential from the mid-1970s to the mid-1980s (primarily in North America and Western Europe), encourages women to direct their energies toward other women rather than men, and often advocates lesbianism as the logical result of feminism. Some key thinkers and activists in lesbian feminism are Charlotte Bunch, Rita Mae Brown, Adrienne Rich, Audre Lorde, Marilyn Frye, Mary Daly, Sheila Jeffreys and Monique Wittig (although the latter is more commonly associated with the emergence of queer theory). As with Gay Liberation, the lesbian feminism understanding of the lesbian potential in all women was at odds with the minority-rights framework of the Gay Rights movement. Many women of the Gay Liberation movement felt frustrated at the domination of the movement by men and formed separate organisations; some who felt gender differences between men and women could not be resolved developed "lesbian separatism", influenced by writings such as Jill Johnston's 1973 book "Lesbian Nation". Disagreements between different political philosophies were, at times, extremely heated, and became known as the lesbian sex wars, clashing in particular over views on sadomasochism, prostitution and transsexuality.
