It was a war fought to centralize power in DC. Power is all it ever was.
I believe that is a reasoned charge.
I think much of it is open to serious debate even today.
The Civil War is a much more important event than most folks think it was. It wasn’t simply about Slavery. There are states right issues that are valid.
There are dynamics at play between loyalist states and the Confederate ones.
We spend too little time discussing these issues, but they are valid points to ponder.
