The claim that the Civil War wasn’t over slavery is false.

The recent brouhaha over the Confederate flag after the mass shooting by Dylan Roof of black members of a Charleston church brought out a lot of old arguments about the Civil War by folks defending the flag. The most common of which is the claim that the Civil War wasn’t about slavery. A claim that is clearly wrong to¬†anyone who has spent much time studying American history.

In a (possibly vain) attempt to settle the matter, the folks at Prager University enlisted the aid of Colonel Ty Seidule, Professor of History at the United States Military Academy at West Point, to speak on the topic:

That explanation is simple and concise and is something you can share with your crazy right-wing uncle the next time he starts ranting about slavery not being the reason the Civil War happened. It probably won’t convince him because those folks tend to be immune to reality, but at least you can save some typing.

Updated to add: This video should be particularly persuasive to Conservatives given that Prager University is the brainchild of Conservative radio talk show host Dennis Prager. So this isn’t the work of one of us wussy liberals, but of one of your own.
