Uncle Tom's Cabin

Explanation:

Uncle Tom's Cabin offered a strong critique of slavery, and convinced many people to support abolition. However, a remarkable quality of this novel is that it not only criticized the position of the South. In fact, the novel also criticized the so-called moral righteousness of the North. It argued that even though many people in the North supported abolition, these same people did not think of African people as equally important and deserving of rights as white people.
