Final answer:
Debates on slavery in the 19th century were fueled by territorial organization, failed compromises, and divisive acts like the Kansas-Nebraska Act.
Explanation:
The debates over slavery in 1820, 1850, and 1854 were primarily provoked by:
- The attempt to organize western territories into states: This raised questions about the expansion of slavery, with Southerners advocating for its extension to new territories while Northerners opposed.
- The Compromise of 1850: Tried to ease tensions but failed as subsequent events like the Fugitive Slave Act and Dred Scott decision heightened sectional hostilities.
- The Kansas-Nebraska Act of 1854: Intensified the slavery debate leading to further division between North and South.
