How did the victory of the mexican war affect the issue of slavery

“The Abolitionists,” learn how the Mexican-American War of 1846–1848 affected efforts to abolish slavery. While driven by economic ambitions and a sense that the United States was “destined” to span the entire continent, the war also raised the issue of how acquisition of such a large territory would affect the balance between slave and free states. The congressional response—the Great Compromise of 1850—not only allowed for the possible creation of new slave states, but also placed legal demands upon northerners to aid in the recapture of fugitive slaves.
