* The North was largely anti-slavery, while the South was largely pro-slavery. Lincoln's election was seen by many in the South as a threat to their way of life.
* Lincoln's election was the final straw for many Southerners. They felt that their interests were no longer being represented in the federal government.
* The election of Lincoln led directly to the secession of several Southern states and the start of the Civil War.
Here are some specific examples of how Lincoln's election reflected the break between North and South:
* The Southern states that seceded from the Union after Lincoln's election cited his election as one of the reasons for their secession.
* The Confederate Constitution explicitly stated that slavery was to be protected and that the federal government could not interfere with slavery.
* The first shots of the Civil War were fired at Fort Sumter in South Carolina, a state that had seceded from the Union after Lincoln's election.
Lincoln's election was a major turning point in American history. It marked the end of the Union as it had been known and the beginning of a new era of conflict and division.
