Susan B. Anthony and Elizabeth Cady Stanton form the National Woman Suffrage Association in New York. Anthony and Stanton have split from the American Equal Rights Association over the Fifteenth Amendment.
Susan B. Anthony, Elizabeth Cady Stanton, and other supporters of women's suffrage oppose the Fifteenth Amendment ("The right of citizens of the United States to vote shall not be denied or abridged by the United States or by any State on account of race, color, or previous condition of servitude.") unless women are included. The American Equal Rights Association supports it anyway, regarding it as better than nothing
The new National Woman Suffrage Association allows men to join and help promote women's suffrage, but all leadership positions are restricted to women.
