Walker’s wild appeal against the trend of the times showed how the world was changing after the coming of the cotton-gin. By 1830 slavery seemed hopelessly fastened on the South, and the slaves thoroughly cowed into submission. The free Negroes of the North, inspired by the mulatto immigrants from the West Indies, began to change the basis of their demands; they recognized the slavery of slaves, but insisted that they themselves were freemen, and sought assimilation and amalgamation with the nation on the same terms with other men. Thus, Forten and Purvis of Philadelphia, Shad of Wilmington, Du Bois of New Haven, Barbadoes of Boston, and others, strove singly and together as men, they said, not as slaves; as “people of color,” not as “Negroes.” The trend of the times, however, refused them recognition save in individual and exceptional cases, considered them as one with all the despised blacks, and they soon found themselves striving to keep even the rights they formerly had of voting and working and moving as freemen. Schemes of migration and colonization arose among them; but these they refused to entertain, and they eventually turned to the Abolition movement as a final refuge. Here, led by Remond, Nell, Wells-Brown, and Douglass, a new period of self-assertion and self-development dawned. To be sure, ultimate freedom and assimilation was the ideal before the leaders, but the assertion of the manhood rights of the Negro by himself was the main reliance, and John Brown’s raid was the extreme of its logic. After the war and emancipation, the great form of Frederick Douglass, the greatest of American Negro leaders, still led the host. Self-assertion, especially in political lines, was the main programme, and behind Douglass came Elliot, Bruce, and Langston, and the Reconstruction politicians, and, less conspicuous but of greater social significance, Alexander Crummell and Bishop Daniel Payne.
