Before the Civil War, slavery expanded in the South rather than in the North because A) Congress passed a law forbidding slavery
in the North. B) Northern states passed affirmative action legislation. C) geography in the South promoted development of large plantations. D) the Constitution contained a clause that outlawed the importation of slaves into the Northern states.
The north didn't really need slaves (doesn't mean they didn't have any), the South, however, thrived by using slaves because of the free labor on their plantations.
