During the Progressive Era, race was set in place for African American women. Their organization focus mainly more on fighting against racism and provide mutual support then having to focus on rights for education, health care, political corruption, and etc. Hundred and thousands of African American women migrated from the South to the North.

Despite their large number of organization and successful reform efforts they still get excluded from white women General Federation of Women's Club and the National American Woman Suffrage Association. White women also ignored issues of racism, such as lynching or the rights of African American voters.
