In the South, frontier areas that lacked transportation, such as the Appalachian Mountains region, remained based on subsistence farming and resembled the egalitarianism of their northern counterparts, although they had a larger upper-class of slaveowners. North Carolina was representative. However, frontier areas of 1700 that had good river connections were increasingly transformed into plantation agriculture. Rich men came in, bought up the good land, and worked it with slaves. The area was no longer "frontier". It had a stratified society comprising a powerful upper-class white landowning gentry, a small middle-class, a fairly large group of landless or tenant white farmers, and a growing slave population at the bottom of the social pyramid. Unlike the North, where small towns and even cities were common, the South was overwhelmingly rural.
