Uncle Tom's Cabin by Harriet Beecher Stowe and Narrative of the Life of Frederick Douglass, an American Slave by Frederick Douglass were two influential works that helped shape the debate around slavery in the United States in the 1800s. Both works brought emotional and factual accounts of the cruel realities of slavery to wide audiences, countering pro-slavery arguments. While Stowe's novel reached more mainstream white audiences, Douglass' memoir provided critical perspective as one of the few widely published first-person accounts by a former slave. Together, these works galvanized anti-slavery supporters and intensified the growing national divide over slavery that eventually led to the Civil War.
