I don't think you meant this the way it was said. Slavery was not begun in the Southeastern United States. It was begun before history was written. It was ended by Europeon white males in the United States.
"Although the South would have preferred any honourable compromise to the fratricidal war which has taken place, she now accepts in good faith its constitutional results, and receives without reserve the amendment which has already been made to the constitution for the extinction of slavery. This is an event that has long been sought, though in a different way, and by none has it been more earnestly desired than by citizens of Virginia." Gen. R.E.
Slavery and racial relations in the South are a difficult subject. As a many-generation Southerner (the first of my white ancestors came over from Scotland in the early 1600's to raise tobacco) the whole thing is not overly pleasant to talk about, and it is really not possible to wrap it all up into a neat little generalizing phrase or two. But then, if it were not for the complications of history and its lingering affects on the present, history enthusiasts would not have so much interesting stuff to envelop themselves in.
