The sentiments expressed in the excerpt were most directly a reaction to which of the following developments?
- AThe ratification of the Fourteenth Amendment granting citizenship to formerly enslaved people
- BThe federal government's attempt to enforce popular sovereignty in the Kansas territory
- The acquisition of new territory following the Mexican-American WarAnswer
- DThe outbreak of the Civil War following the secession of southern states
Answer
The acquisition of new territory following the Mexican-American War
The correct option is correct because the defeat of Mexico in 1848 led to the Treaty of Guadalupe Hidalgo, which granted the United States the Mexican Cession (including present-day California, Utah, Nevada, and parts of Arizona, New Mexico, Colorado, and Wyoming). The prospect of organizing these new territories reopened the national debate over the expansion of slavery, prompting anti-slavery advocates to form the Free Soil Party in 1848 to demand that all newly acquired lands remain free of slavery.
