Why did slavery continue to be an import political issue in the 1830’s?

because the north stopped doing slavery but the south kept going

Explanation:

why was that? the north realized that what they were doing was wrong and they were getting lazy but the south was not stopping and they were getting lazy but in the late 1850s the confederates were beginning to stop but the united states taxed them badly and that is how the civil war started ( oh! by the way the American civil war was about money).
