Step-by-step explanation:
Uncle Tom's Cabin further divided the nation between free and slave states by galvanizing anti-slavery sentiments in the North. The novel, written by Harriet Beecher Stowe, depicted the harsh conditions of slavery, the separation of families, and the corruption of white slaveholders. It had a significant impact in the North, selling over 300,000 copies in its first year and causing people to think about the moral implications of slavery. However, it also faced protest and criticism in the South, with many considering it slanderous.
