150 years later, the question remains: Was the Civil War About Slavery?

What caused the Civil War? Did the North care about abolishing slavery? Did the South secede because of slavery? Or was it about something else entirely...perhaps states' rights? Did Abraham Lincoln state that slavery should exist in all of America, both North and South?

Colonel Ty Seidule, Professor of History at the United States Military Academy at West Point, settles the debate in the above video presentation.
