What was the unintended consequence of the territory gained by the United States in the Mexican-American War that fulfilled Manifest Destiny?
a. The number of people that spoke Spanish as their first language rose greatly creating the need for English education programs.
b. The new territories gained from Mexico were heavily Catholic.
c. The balance between states that allowed the enslavement of people and those that were free states became unbalanced.
d. An increase in the amount of money that was required by the US Army to defend the new territory from invasion.

This is because Southerners wanted to expand territory into the west and the Compromise of 1850 decided if Calfornia should be a free or slave state. California decided to be a free state so Southern politicians made it so that the territories of New Mexico and Utah could freely vote for slavery themselves. This also led to the Fugitive Slave Act of 1850 (extremely controversial) which allowed Southerners to recapture their escaped slaves.
