Actually, the first slaves were sold by British slave traders. The Yankees were latecomers to that game, and became involved as the British stopped slavery under Wilberforce.
My whole point is that the South didn’t introduce slavery.
The entire Southern economy was very much dependent on slavery, whereas the North became industrial. Many good men in power knew that slavery needed to go, but had no easy solution to the problem. Then came the abolitionists......
One thing about Southrons, we don’t like people butting into our business.
