The southern states have their own accent, culture, history and climate that's different from the northern states. In the 1800's, the country became divided when the southern states refused to give up slavery because their main product was agriculture and and all those slaves kept their farms/plantations running. That's what sparked the american civil war 1861-1865. The north won, led by president Abraham Lincoln who abolished slavery for good in the US.

Some of these husbands were not anxious to liberate their wives immediately. They considered it advisable to put them on probation for a few years, and if they did not find them satisfactory they would sell their wives as other slaveholders disposed of Negroes. For example, a Negro shoemaker in Charleston, South Carolina, purchased his wife for $700; but, on finding her hard to please, he sold her a few months thereafter for $750, gaining $50 by the transaction.
