How did slavery cause sectionalism in the antebellum era? a. southern politicians supported the expansion of slavery into new states. b. northern politicians backed the spreading of slavery only into far western territories. c. the south wanted slavery to continue in existing states but not in new states. d. the north wanted slavery to expand slavery into only a few northern states.

The correct answer is A) Southern politicians supported the expansion of slavery into new states.

During the Antebellum Era (1820-1860) the United States expanded rapidly during the era of westward expansion. This resulted in the US acquiring houndreds of thousands of square miles of land through purchases, wars, and other treaties. When these territories wanted to become states, the question of whether or not slavery would exist was always a central issue. Northerners did not want slavery to spread, as this would result in slave states gaining more power in Congress.
