Final answer:
The Mexican-American War contributed to sectionalism between the North and South through the debate over the expansion of slavery. The Compromise of 1850 further escalated these tensions.
Step-by-step explanation:
The Mexican-American War played a significant role in fueling sectionalism between the North and the South in the United States. The acquisition of new territories from Mexico, such as California and Texas, intensified the debate over the expansion of slavery. The North and South held contrasting views on the issue, with the North opposing the spread of slavery and the South advocating for its expansion.
This sectional divide was highlighted by the debates and negotiations surrounding the Compromise of 1850, which aimed to address various issues stemming from the Mexican-American War. The compromise, while ultimately a temporary solution, solidified the tensions between the North and South and further deepened the divide between the regions.
