Black feminism essentially argues that sexism an racism are inextricable from one another. It is not restricted to black women, but rather designed an inner current of feminism which tied together gender domination with racism and capitalism; in the 1970s, it included women from Chicano origins, Chinese, or "Third World" origins . Patricia Hill-Collins defined Black feminism, in Black Feminist Thought (1991), as including "women who theorize the experiences and ideas shared by ordinary black women that provide a unique angle of vision on self, community, and society" .
