CHAPTER NINE: The Changing South

A brief information about the Reconstruction that lead to a Changing South: "During Reconstruction, industrial and commercial projects began to restore the economy of the South, and new programs were developed such as public school systems. These improvements, however, failed to ensure racial equality, and former slaves remained, in most cases, landless labourers, although emancipated slaves were assisted in finding work, shelter, and lost relatives through federal agencies.

Johnson's failure to work with moderate Republicans in guaranteeing basic rights and protection for the freed slaves caused a Radical triumph in the elections of 1866, ushering in a period of ‘Radical Reconstruction’, and opened the way for military reconstruction. The Reconstruction Acts of 1867 began this process, dividing the Southern states (except Tennessee, which had been readmitted to the Union in 1866) into five military districts. Civilian rule and full state rights were to be restored only after the states had adopted constitutions based upon universal male suffrage and ratified the Fourteenth Amendment. By 1868 all but three states were readmitted under these conditions, Mississippi, Texas, and Virginia finally acquiescing in 1870. The Fifteenth Amendment ratified in March 1870, aimed to guarantee black suffrage in the South.
Despite the legislation, many Southern states still practised discrimination and segregation. Jim Crow Laws disenfranchised blacks in every Southern state, making them powerless to prevent these segregation laws and codes."

The changing south derives from creating a new southern part of United States, with the effort of creating a beginning from the horrible past it adheres. The Changing South has no connection to San Francisco in the West.
