Uncle Tom's Cabin; or, Life Among the Lowly is an anti-slavery novel by American author Harriet Beecher Stowe. Published in 1852, the novel had a profound effect on attitudes toward African Americans and slavery in the U.S. and is said to have "helped lay the groundwork for the Civil War".
Both the union and confederate utilized private sectors as their main force of economy and both of them also heavily involved in agricultural sectors.
The thing that distinguish the two of them were the confederate relies too heavily on slave labour while the northern states relied on manufacturing equipment/technologies.
