The Fourteenth Amendment had been ratified in July 1868, but Republicans found it inadequate because it did not specifically enfranchise Negroes. More than ever convinced that they needed the Negro vote in order to continue in power, they prepared to supplement it by a Fifteenth Amendment, which Susan hoped would be drafted to enfranchise women as well as Negroes. Immediately through her Woman's Suffrage Association of America, she petitioned Congress to make no distinction between men and women in any amendment extending or regulating suffrage. She and Elizabeth Stanton also persuaded their good friends, Senator Pomeroy of Kansas and Congressman Julian of Indiana, to introduce in December 1868 resolutions providing that suffrage be based on citizenship, be regulated by Congress, and that all citizens, native or naturalized, enjoy this right without distinction of race, color, or sex. Before the end of the month, Senator Wilson of Massachusetts and Congressman Julian had introduced other resolutions to enfranchise women in the District of Columbia and in the territories. Even the New York _Herald_ could see no reason why "the experiment" of woman suffrage should not be tried in the District of Columbia.[232] To focus attention on woman suffrage at this crucial time, Susan, in January 1869, called together the first woman suffrage convention ever held in Washington. No only did it attract women from as far west as Illinois, Missouri, and Kansas, but Senator Pomeroy lent it importance by his opening speech, and through the detailed and respectful reporting of the New York _World_ and of Grace Greenwood of the Philadelphia _Press_ it received nationwide notice. Congress, however, gave little heed to women's demands. "The experiment" of woman suffrage in the District of Columbia was not tried and nothing came of the resolutions for universal suffrage introduced by Pomeroy, Julian, and Wilson. In spite of all Susan's efforts to have the word "sex" added to the Fifteenth Amendment, she soon faced the bitter disappointment of seeing a version ignoring women submitted to the states for ratification: "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." The blatant omission of the word "sex" forced Susan and Mrs. Stanton to initiate an amendment of their own, a Sixteenth Amendment, and again Congressman Julian came to their aid, although he too regarded Negro suffrage as more "immediately important and absorbing"[233] than suffrage for women. On March 15, 1869, at one of the first sessions of the newly elected Congress, he introduced an amendment to the Constitution, providing that the right of suffrage be based on citizenship without any distinction or discrimination because of sex. This was the first federal woman suffrage amendment ever proposed in Congress.
