Why didn't reconstruction work after the civil war?

Reconstruction didn't work after the civil war because the goal of reconstruction was to reintroduce the south back into the union as quickly as possible. There would be no real victory from the war unless the country was put back together. After the south was defeated in 1865 the reconstruction act of 1867 was set into place. Although slaves were freed the south established Black codes that treated the Blacks as slaves but weren't considered slaves. It set limitations on them so it kept them at the bottom of the food chain. Reconstruction ended in 1877 because the military pulled out of the south. The north got tired of spending so much money on the Reconstruction when little was being achieved. Ultimately reconstruction did work just not at the time that the north wanted it to work.
