Well shit, why are you downvoted? For linking to documents that dare to "revise" history and look for original source material to determine why the United States went to war?

Most curious in your first link is the fact that of the four states whose declarations of causes were evaluated, South Carolina used more of the document to argue for states' rights than slavery (37%, 20%).

Obviously slavery had a huge part to do with the conflict, but for a state that still had the Confederate States of America's flag over their capital, it seems their primary reason for war was to preserve their rights as a state in the union.
