What caused The Civil War?

The Civil War was not caused by one single act, opinion, or decision, but by many of those all blended together. The South and North believe the war started for different reasons, but they both may necessarily be correct or incorrect. Three of the main reasons our of many reasons are the South wanting to preserve slavery and their slave society, the fear among the people, as well as Political fear. The North's reasoning for the war is mostly opposing or just different than the South's.
The South's reasoning for the war happening is much different than the North's reasoning because they have different views on slavery. For example, the South defends the Constitution and the North defends the mob rule and anarchy. The South and North also have opposing opinions as to why succession occurred, which helped add to the list of reasons why The Civil War occurred. With the South believing that secession occurred partially because of the South wanting to preserve and protect their slavery and slave society and the North going against the idea of secession completely caused the two different society's to bump heads and caused controversy. For example there is an excerpt from a northern soldier and he says to his wife: "A pure love of my country and of the principles I have so often advocated before the people- another name of Honor that I love more than I fear death- has called upon me and I have obeyed." This is an example of how the Northerners felt about the civil war and why they fought in it. Most Northerners believed that they were protecting their country and that the South was going against it. They felt threatened and as if they had to protect themselves and their country. Also the difference in the work or labor forces led up to the North and South arguing as well. The South believed that slavery was much better for the people because they had absolutely nothing to worry about and had everything for them from their masters. They believed that after a hard days work the slaves were happy to know they were going to have a meal and a bed to sleep in. The North disagreed strongly and believed in free-market and competition for jobs and everything around them. They thought that the free market and competition for jobs was the best thing for their society, but it turned out to be much harder than they expected.
Back to the reason of the fear of the people in the South, Professor Blight states something that Lincoln says about this idea while in office that captures the idea: " It is a course of ultimate extinction". Going along with the idea of fear, another cause of secession that also led to the war was Political Fear. The South began to fear when Lincoln got to decide who was in Supreme Court. This feared the South because Lincoln was a Republican therefore he was clearly going to choose a Republican, which meant less political power for the South. There are many different reasons and events as to why the Civil Was was caused; Fear among the people, Political fear, and protecting slave society were just a few reasons. Also, differences in the work forces that brought up much controversy added to the cause.
