Exactly what I thought when you brought up marxists. The subject fits you perfectly.
Fits me perfectly? Hardly, I don’t subscribe to the Marx and Engel’s interpretation of the American Civil War.
I brought up Marx and Engels because they wrote extensively on the American Civil War, and their account is significant because it is virtually identical to the interpretation of Civil War history that many South-haters use today.
It’s an interesting question where South-haters get their interpretation. Maybe they stumble upon it all by themselves. More likely they absorb Marx and Engels as it filters through other historians. It’s not like the American Historical Association has had a shortage of marxists. Eric Foner being a classic example of one who writes on the Civil War.
