Southern states enacted "Black Codes" in 1865 and 1866, which are laws that limit the freedom of Blacks in the area. These laws were seen as a ploy to circumvent the 13th amendment in the north and keep slavery legal under new names. Vagrancy laws, which enabled for the newly emancipated Black populace to be imprisoned and given a hard labour term, were the distinguishing aspect of the post-Civil War Black Codes. The Radical Republican Congress responded in 1866 by imposing military authority on the South as part of their Reconstruction plan and bypassing several laws, including the Civil Rights Act of 1866 and the 14th Amendment. Till 1877, the military would undergo reconstruction.
