Universal suffrage proposals first emerged during the Reconstruction era (1865-1877). Suffragists later modeled their proposal after the 15th Amendment (1870) and settled on language to end sex discrimination in voting. First proposed in 1878, the “Susan B. Anthony Amendment” was introduced in each Congress—unchanged—for the next four decades. Congress finally approved it on June 4, 1919. The 19th Amendment was ratified on August 18, 1920.
