"At the root of all the war was the institution of slavery, which had been introduced into North America in early colonial times," says James F. Epperson. The basis of the Civil War was to end the practice of slavery. In the Northern section of the United States of America slavery was banned, therefore they did not want the "evil sin" to move on to the west, where the new frontier was being built. The Southern section of the already established states felt the exact opposite, they wanted to see slavery move into the new frontier. There were many arguments between the North on the South about slavery and about ending it. Because of the different points of view between the two sections of our country, the only result they say to solve the problem was war, a war that we know of as The Civil War.
In the newly established United States, slavery flourished in the South and failed in the North, except in New York City and southern New Jersey. This had little to do with morality and alot to do with climate and economy. When the Northern states gave up the last remnants of legal slavery, in the generation after the Revolution, their motives were a mix of morality, and ethics, there was also fear of a growing black population and the fact that the Revolutionary War had broken the Northern slaveowners power. But generally a few people illegally had a small number of Northern slaves. Other that, the Northern leadership turned its back on slavery. The language of the Declaration of Independence, and the great talks of equality, also helped place slavery in an ethically precarious position in the minds of many. Abolition societies formed in Wilmington and Dover in 1788 and 1789. Wilmington eventually became a place of the Underground Railroad.
the South's economy was based on large farms (plantations) using slave labor. In the 1840s and '50s the Northern states wanted to prohibit slavery in the Western territories that would eventually become new states.
