After the Civil War, when the 15th Amendment giving Blacks the right to vote was being debated, Douglass split with the Stanton-led faction of the women's rights movement. Douglass supported the amendment, which would grant suffrage to black men. Stanton opposed the 15th Amendment because it limited expansion of suffrage to black men; she predicted its passage would delay for decades the cause for women's right to vote.
