I call it the First Democrat-Republican War. The Left is responsible for calling it North Vs. South. If you take a look at the Senators expelled from the Senate during that time you will notice something amazingly common to both.
Considering the Radical Republicans close association with European revolutionaries including Karl Marx it could easily be the first communist vs American war.
Read Marx’s writing on the Civil War with the current crop of South haters and you won’t be able to see a difference.
