The Civil War initially was about preserving the union and with the issuance of the emancipation proclamation then became a war to end slavery. With the assassination of Lincoln the radical republicans would then attempt to impose equality on the South. This effort would end with the presidential election of Rutherford B. Hayes.
Jim Crow would then impose a social enslavement on our black citizens. These citizens have never been fully integrated into our society and unfortunately the millions of illegal immigrant are impacting on our ability to accomplish this as much and as fast as possible.
