You said, the Confederate War was the 2nd war of Independence. So I asked, for who & how so? Actually, slavery became an issue way, way before the Civil War. Thomas Hart Benton even predicted the slave industry/issue becoming a major political component after the Adam's Onis Treaty was signed, and he was correct. Why did he know this? He knew this because A) he understood the economic value and importance of it, and, B) he knew many of the driving forces that were going to make it a political issue at every chance. The slave rebellion in Hati was just the first stone cast into the water, many could see the writing on the wall after this.
