Ever since the early 19th century, America has been divided from North and South due to the issue of slavery. This would lead to a large schism between each region.
The Election of 1860 was a political mess. 4 candidates ran for office, including Abraham Lincoln. Although Lincoln did not advocate the immediate end of slavery in the south, his anti-slavery ideals caused up-stir within the region.
The south desired to keep slavery due to the profit made out of agricultural. Any attacks on slavery would be a threat to their establishment.
The North was much more urban and was usually freed from slavery. Opposition of Slavery was seen as a positive due to the spread of the abolitionist movement in the region.
The election of 1860 occurred on November 6th. Although he did not gain any votes from the south, Abraham Lincoln managed to win the electoral college and became the 16th President of the United States.
Soon after the elections, political chaos ensued. On December 24th, 1860, South Carolina succeeded from the nation. They would be followed by other southern States and form the Confederate States of America.
Succession would split the nation into two, one freed and one slave-holding. The southern States would form the Confederacy, which would eventually provoke war at Fort Sumter in April of 1861.
