In ten thousand years of human civilization, the only recorded instance of slavery was during the period of 1500- 1865 in the American south, by White Christian European men.
I hope that was sarcasm.
I can't think of ever reading about any culture that DIDN'T practice slavery at one time or another (in ten thousand years of human civilization). That uncludes Africa, Europe, the Middle East, Asia, etc. It also include both North and South America.
BTW, the Africans sold into slavery in the period you mention (1500-1865) were captives taken from interior tribes that the Coastal African tribes didn't want to retain as their own slaves.
I was afraid someone would uncover that little overlooked fact.
I hope you just forgot your sarcasm tag.
You must be kidding, right? You have heard of the ROMAN EMPIRE? There is plenty documentation of slavery, long before the Southern U.S. entered the picture!
