Step-by-step explanation:
Reconstruction was predominantly a failure.... it did not extend improvments to African Americans, and it failed to rebuild the south. Under Johnson, southern property was given back to its previous owners and The South was practically left on its own to resolve issues. Then, the South managed to enact black codes (segregation laws). Eventually more radical republicans stepped in, putting military power in the south and forced them to adhere to the 14th and 15th amendment and well as the 13th they had to follow prior. Some successes it had was implementing the South's first state funded public schools, putting some laws against racial discrimination (though rasicm persisted), and restored the Union after the Civil War. Hope this helps (I've been studying a lot for my AP US History test in two days) :)
