Guess you’ve never read the Confederate Constitution, have you?
You seem to not understand that it is your Government that taught you your history.
It is not what the Confederate Constitution said about slavery that caused the Union to invade it. It was what it said about being independent of the Union's financial controls that convinced the Union that it had to be invaded.
The South's reasons for leaving don't matter. Presumably if they left because they didn't like Northern grown apples, the Union would still have invaded. It is the North's reasons for sending men to die to stop Independence that matter.
Those reasons boil down to money. Who would lose it, and who would gain it.
I have. Slavery in the US was an accepted practice. Most of these people from Africa sold by Muslims to traders in Boston.
It became the rally point for the North when in reality it was going away by its own volition. 40 acres and a mule!
Uh huh.........
It was the river............
