  Current feminist political philosophy is indebted to the work of earlier generations of feminist scholarship and activism, including the first wave of feminism in the English-speaking world, which took place from the 1840s to the 1920s and focused on improving the political, educational, and economic system primarily for middle-class women. Its greatest achievements were to develop a language of equal rights for women and to garner women the right to vote. It is also indebted to the second wave of feminism, which, beginning in the 1960s, drew on the language of the civil rights movements (e.g., the language of liberation) and on a new feminist consciousness that emerged through women’s solidarity movements and new forms of reflection that uncovered sexist attitudes and impediments throughout the whole of society. By 1970, feminism had expanded from activism to scholarship with the publication of Shulamith Firestone’s The Dialectic of Sex (Firestone 1971); Kate Millett’s Sexual Politics (Millett 1970); and Robin Morgan’s Sisterhood is Powerful (Morgan 1970).
