Reconstruction era in why it was a failure

Was Reconstruction a failure or a success?  Explain your point of view with 4-5 examples that prove your perspective. I have chosen to prove that it was a failure, along with my thesis which can be reworked and all the primary and secondary sources to be used. There is also an outline which can also be reworked it is purely a guide with the points to prove, it does not have to follow that order, but the topics of the outline and my thesis are what’s important, as these are the points that should be used in the argument of why the reconstruction era was a failure.
