Final answer:
Ida B. Wells stood up against racial discrimination within the women's suffrage movement by joining her white Illinois peers in the 1913 Washington, D.C. suffrage parade instead of marching at the back as black women were instructed to do.
Step-by-step explanation:
Ida B. Wells was a prominent figure in the fight for racial justice and women's suffrage. Despite having been a long-standing member of the National American Woman Suffrage Association (NAWSA), she faced discrimination within the group, leading her to advocate for black women's voting rights independently through the creation of the National Association of Colored Women Clubs.
During the suffrage parade in 1913 Washington, D.C., Wells bravely challenged the racist policy of segregation by refusing to march at the back, stepping into the procession with her white Illinois peers as they passed to assert her place in the movement for gender equality.
