The answer is slavery. The Republicans were anti-slavery, while the democratic south was pro slavery. Eventually that, and a couple of other things, led to the Civil War.
Sorry if this was a bit late, Brainly had just recommended this question for me to answer, but I hope this helps!
Choose B: a book written by a historian who is an expert on medieval Europe.
I trust that book because the book was written by an EXPERT. Someone who is trustworthy and knows more about a student-produced website.
The election of Abraham Lincoln split the United States tremendously. With the election of Lincoln, southerners feared that their way of life was in danger. They felt that Lincoln's election would eventual result in outlawing the institution of slavery.
This fear caused southern states to take dramatic action. Roughly one month after the election of Lincoln, South Carolina seceded (left) the United States. After South Carolina, states like Florida, Alabama, and Mississippi seceded as well. Ultimately the secession of states like this resulted in the creation of the Confederate States of America, which sets the scene for the Civil War.
