The National Woman Suffrage Association (NWSA) was formed on May 15, 1869 to work for women's suffrage in the United States. Its main leaders were Susan B. Anthony and Elizabeth Cady Stanton. It was created after the women's rights movement split over the proposed Fifteenth Amendment to the U. S. Constitution, which would in effect extend voting rights to black men. One wing of the movement supported the amendment while the other, the wing that formed the NWSA, opposed it, insisting that voting rights be extended to all women and all African Americans at the same time.
