by the mid-1870s, when the North withdrew its oversight in the face of southern hostility, whites in the South began to resurrect the caste system founded under slavery. Nursing the wounds of defeat and seeking a scapegoat, much like Germany in the years leading up to Nazism, they began to undo the opportunities accorded freed slaves during Reconstruction and to refine the language of white supremacy. They would create a caste system based not on pedigree and title, as in Europe, but solely on race, and which, by law, disallowed any movement of the lowest caste into the mainstream.
