Slavery had a big impact on America. The northern part of the U.S. didn't want slavery because a large amount of their economy didn't involve slaves, and wouldn't be affected if the slaves were set free. On the other hand in the Southern states slavery, was a major thing when it came to dealing with the economy, since most of the work was done by slavery. But, in the West, many of the new states to the U.S. were being thought of as not a slave state, which drove some congregational members into a frenzy. This problem didvided up America in many ways.
