How did abraham licoln and Jefferson Davis each use the ideals of the american revolution and the declaration of independance to support their side's cause

The Confederacy saw themselves as fighting a second war for independence. They were rebelling against what they felt was an oppressive government that was infringing on their rights.

Lincoln referenced the forefathers in his Gettysburg Address and felt that keeping the union together was what they had fought for, they created a new nation, not one that should be torn apart.
