We discussed this quite a bit during a class I took on slave uprisings and rebellions. Would anyone care to discuss why they believe there was only one successful slave rebellion? It seems to me that numbers were not an issue for the most part. I have my own opinion as to why certain rebellions (Nat Turner's, for example) failed in freeing slaves. To be clear: my definition of a SUCCESSFUL rebellion is one in which slaves were no longer being held in bondage.

Where are you getting the idea of only one successful slave rebellion?
