Question

select the correct answer. which war resulted in territorial gains for the united states that caused sectional conflict in the years leading up to the civil war? a. revolutionary war b. war of 1812 c. mexican war d. spanish - american war

Explanation:

The Mexican - American War (1846 - 1848) led to significant territorial gains for the United States, such as the acquisition of present - day California, Nevada, Utah, Arizona, New Mexico, and parts of Colorado and Wyoming. These new territories exacerbated sectional conflict over issues like slavery expansion, which contributed to the tensions leading up to the Civil War. The War of 1812 did not result in major territorial gains for the US in the context of pre - Civil War sectional conflict. The Revolutionary War was about the US gaining independence, not territorial gains related to pre - Civil War sectional issues. The Spanish - American War occurred after the Civil War.

Answer:

C. Mexican War
