The original Ku Klux Klan was organized by ex-Confederate elements to oppose the Reconstruction policies of the radical Republican Congress and to maintain white supremacy..
The whites were reluctant to help the blacks if their life was on the line, and many decided not to help. The KKK effectively caused reconstruction to falter because they stopped blacks from using their new freedoms and forced people trying to expand reconstruction out. Therefore, the South, specifically the Ku Klux Klan, killed the reconstruction.
