African American women, such as Ida B. Wells and Mary Church Terrell, actively campaigned for women’s suffrage, but they generally worked within their own groups rather than organizations such as the National American Woman Suffrage Association.
They had good reasons for this.
In a speech at the 1903 NAWSA convention, white southerner Belle Kearney pointed out how woman suffrage could help counter the black male vote and in this way preserve white rule.
Southern NAWSA groups were then allowed to set up their own membership criteria and did not have to admit African American women.
Some white southern women later formed groups to get states to give the vote to white but not black women.
The founding members of the National Association for the Advancement of Colored People in 1909 included such black women activists as Ida B. Wells and Mary Church Terrell and such white social reformers as lane Addams and Mary White Ovington.
