nationalism, or the Black Panther Party established, as an offshoot of the National Black Feminist Organization, the Combahee River Collective, a radical lesbian feminist group. Their founding text referred to important female figures of the abolitionist movement, such as Sojourner Truth, Harriet Tubman, Frances E. W. Harper, Ida B. Welles Barnett, and Mary Church Terrell, president of the National Association of Colored Women founded in 1896. The Combahee River Collective opposed the practice of lesbian separatism, considering that, in practice, separatists focused exclusively on sexist oppression and not on other oppressions (race, class, etc.) The Combahee River Collective The Combahee River Collective (1974-1980) was one of the most important Black socialist feminist organizations of all time. This group began meeting in Boston in 1974, a time when socialist feminism was thriving in Boston. The name Combahee River Collective was suggested by the founder and African-American lesbian feminist, Barbara Smith, and refers to the campaign led by Harriet Tubman, who freed 750 slaves near the Combahee River in South Carolina in 1863. Smith said they wanted the name to mean something to African-American women and that "it was a way of talking about ourselves being on a continuum of Black struggle, of Black women's struggle". The members of this organization consisted of many former members of other political organizations that worked within the civil rights movement, anti-war movement, labor movement, and others. Demita Frazier, co-founder of the Combahee River Collective, says these women from other movements found themselves "in conflict with the lack of a feminist analysis and in many cases were left feeling divided against [themselves]." The Combahee River Collective argued in 1974 that the liberation of Black women entails freedom for all people, since it would require the end of racism, sexism, and class oppression. Within the Black Feminisms: Combahee River Collective Statement of 1977, they spoke on how it is, “...difficult to separate race from class from sex oppression because in our [black women's’] lives they are the most often experienced simultaneously". The Combahee River Collective articulated this interlocking system of oppression based on sexism, heterosexism, racism, and classism is due to the lack of basic human rights provided to black women in comparison to other groups, such as white women. This is crucial to the political beliefs of black feminism due to their difference among other groups, as they tackle additional struggles others don't necessarily experience. White
