 White elite-dominated state legislatures passed disenfranchising state constitutions from 1890 to 1908 that effectively barred most blacks and many poor whites from voting.This disenfranchisement affected millions of people for decades into the 20th century, and closed African Americans and poor whites out of the political process in the South.Re-establishment of white supremacy meant that within a decade African Americans were excluded from virtually all local, state, and federal governance in all states of the South.
