Racism was an underlying factor throughout the suffrage movement. The story of how women gained the vote in Kansas in 1912 and nationally in 1920 is a fascinating reflection of American attitudes towards women and its Civil War history. These suffragists formed unlikely coalitions to achieve a political end—the right to vote. Southern states struggled to ratify the 19th amendment in the Jim Crow South where the existing power structure was already threatened by the addition of Negro men as voters—and now, by the addition of black women to the voting rolls .
Elizabeth Cobbs, history professor at Texas A&M, explains in her Washington Post opinion piece from June 3, 2019:
“(T)hough not everything in America is about race, sometimes race is more involved than meets the eye. What took so long for women to win the right to vote? Racism is one reason.”
