Why Did Lincoln Support Slavery?

By 1860, the bridge between the North and the South was quickly growing apart, mainly because of the issue of slavery. South Carolina, one of the most prominent southern states, strongly supported slavery. Therefore, when anti-slavery Abraham Lincoln was elected to be president on November 6, 1860, South Carolina General Assembly passed the "Resolution to Call the Election of Abraham Lincoln as U.S. President a Hostile Act" three days later. This resolution had stated South Carolina’s intention to secede from the Union. The General Assembly formed a convention, the Convention of the People of South Carolina, to discuss and vote on secession. The president of this convention was David Flavel Jamison, a former member of the S.C. House of Representatives.
