would advance to lead the race to a wider variety of occupations. Du Bois and Washington were divided in part by differences in treatment of African Americans in the North versus the South; although both groups suffered discrimination, the mass of blacks in the South were far more constrained by legal segregation and disenfranchisement, which totally excluded most from the political process and system. Many in the North objected to being 'led', and authoritatively spoken for, by a Southern accommodationist strategy which they considered to have been "imposed on them [Southern blacks] primarily by Southern whites". Historian Clarence Earl Walker wrote that, for white Southerners, Free black people were 'matter out of place'. Their emancipation was an affront to southern white freedom. Booker T. Washington did not understand that his program was perceived as subversive of a natural order in which black people were to remain forever subordinate or unfree. Both Washington and Du Bois sought to define the best means post-Civil War to improve the conditions of the African-American community through education. Blacks were solidly Republican in this period, having gained emancipation and suffrage with President Lincoln and his party. Fellow Republican President Ulysses S. Grant defended African Americans' newly won freedom and civil rights in the South by passing laws and using federal force to suppress the Ku Klux Klan, which had committed violence against blacks for years to suppress voting and discourage education. After Federal troops left in 1877 at the end of the Reconstruction era, many paramilitary groups worked to suppress black voting by violence. From 1890 to 1908 Southern states disenfranchised most blacks and many poor whites through constitutional amendments and statutes that created barriers to voter registration and voting. Such devices as poll taxes and subjective literacy tests sharply reduced the number of blacks in voting rolls. By the late nineteenth century, Southern white Democrats defeated some biracial Populist-Republican coalitions and regained power in the state legislatures of the former Confederacy; they passed laws establishing racial segregation and Jim Crow. In the border states and North, blacks continued to exercise the vote; the well-established Maryland African-American community defeated attempts there to disfranchise them. Washington worked and socialized with many national white politicians and industry leaders. He developed the ability to persuade wealthy whites, many of them self-made men, to donate money to black causes by appealing to their values. He argued that the surest
