While many in the North were in favor of states determining their own course, when it came to slavery there was a considerable anti-slavery political faction at work in the North. Although many in New England had grown wealthy in the slave trade before it was banned, that part of the North became a center for abolitionist movements. Beginning in the 1830s, Northern churches and politicians became prominent in the movement. This contributed to the resentment felt by Southerners. Abolitionists took a hard line against slavery and wanted all slaves freed and an immediate end to racial segregation everywhere in the country. Other groups in the North, notably free-soilers wanted to end slavery in the new western territories, but for different reasons. While they didn't have slaves themselves most were prejudiced against black people. They believed the popular idea at the time that blacks were inferior. They wanted the new lands to be for whites only. Southern slaveholders saw little difference between the two groups and only saw they both were against slavery.
