The supporting details that provide support for the central idea of the paragraph are:
- After the Civil War and the emancipation of slaves in the United States, the Fifteenth Amendment, which would give African American men the right to vote, was proposed. This caused a great divide between women suffragists.
- Some women, including Stanton and Anthony, would not support the amendment because they felt that it should extend voting rights to all American citizens.
- Other women, including Lucy Stone and Julia Ward Howe, supported the amendment.
- They believed that once African American men had the vote, women would be next.
All of these details illustrate the differing opinions among women's suffragists regarding the Fifteenth Amendment and highlight the complexities of the women's rights movement in relation to the abolitionist movement and the rights of African Americans.
