True about the issue of slavery in the 1840s and 1850s?

In the 1840s and 1850s, the issue of slavery became increasingly contentious in the United States, contributing to deep regional divisions between the North and South. The debate intensified with the expansion of the U.S. territory following the Mexican-American War, raising questions about whether new states would be free or slave states. Key events, such as the Compromise of 1850 and the publication of Harriet Beecher Stowe's "Uncle Tom's Cabin," highlighted the moral and political conflicts surrounding slavery. This growing tension ultimately set the stage for the Civil War.
