Many 19th-century woman suffragists also sought to end slavery. They flooded Congress with petitions for abolition and for voting rights for all citizens, including women and African American men. After the Civil War the movement temporarily split: some worked for the immediate goal of suffrage for black men; others pursued universal voting rights for woman suffrage. In 1870 the Fifteenth Amendment secured voting rights for men regardless of race; women fought another 50 years for the right to vote.
