Whoever came up with that title needs to be beaten to within an inch of their lives.
The Confederacy was about a LOT more than slavery,and in FACT,there were black Confederate Soldiers. There is at least one "Black Confederate Cemetary" in Virginia. I think there were more,but since nobody wants to talk about them,it's hard to find out where they are.
The War of Southern Independence was NOT about slavery. It was PRIMARILY about free trade and independence from the New York banking cartels getting a cut of all the sales of tobacco and other goods from the south.
Even Lincoln said if it would keep the union together,he was willing to allow slavery to stand.
BTW,there WERE free blacks living in the south,and in FACT,the VERY FIRST SLAVE OWNER in the very first English settlement in what is now called America was a black man who went to court to keep his indentured servant as a slave instead of having to free him.
Can't remember his name now,but he came here as an indentured servant himself,worked off what he owed for his passage and upkeep,and then got a land grant to start his own farm and bring in indentured servants to help him clear the land,plant the crop,and harvest it.
He eventually sold the farm and moved to Maryland (IIRC) and started a horse farm.
