That is exactly what I have discovered about the Civil War. The war was started to protect the financial interests of the Crony Capitalists, especially in New York. It was a war over money that they later re-billed as a war against slavery.
And then they wrote the history books to make it look like the war was a moral crusade instead of protecting their money streams.
Rubbish.
Regardless of how often you repeat such lies, Civil War still began at Fort Sumter over Confederate demands that Lincoln surrender it.
Confederate motives were to defend & expand the Confederacy, Lincoln's motives were to preserve, protect and defend the Union.
Slavery also played a huge role, though behind the scenes on April 12, 1861.
