northern abolitionists
southern slaveholders
non-partisan americans

“Uncle Tom’s Cabin” or “Life Among the Lowly” was a novel published in 1852 written with a strong and carefully anti-slavery argument, therefore, it was intended to the Americans who still supported the slavery, a Christian audience that needed to be convinced of the evil institution in which this practice consisted.
