What were the successes and failures of the reconstruction of the Civil War?

http://en.wikipedia.org/wiki/Reconstruction

if you are talking about the period of reconstruction, some of the successes were three amendments passed the 13th 14th and 15th amendment which benefit former slaves. Some of the failures politically speaking are the constant "battles" between johnson and congress. But the biggest failure of reconstruction was that the laws passed to benefit former slaves were evaded at all costs by groups like the Ku Kwax Klan, and by laws like the black codes, in short the laws were not willingly inforced by white southeners.
