I know the North didn’t go to war to free the slaves. It went to war to preserve the union and it succeed . The South went to war to preserve slavery and lost.
The South did not go to war because of slavery. The South went to war because DC did not adhere to the Constitutional law of States Rights to sovereignty.
It went to war to preserve it's money, which necessarily required the South not to trade directly with Europe at lower tariffs and without protectionist laws.
On 3/18/1861, The Boston Transcript wrote:
“It does not require extraordinary sagacity to perceive that trade is perhaps the controlling motive operating to prevent the return of the seceding States to the Union. “Alleged grievances in regard to slavery were originally the causes for the separation of the cotton States; but it is apparent that the people of the principal seceding states are now for commercial independence. They dream that the centers of traffic can be changed from Northern to Southern ports. “The merchants of New Orleans, Charleston, and Savannah are possessed with the idea that New York, Boston, and Philadelphia may be shorn, in the future, of their mercantile greatness, by a revenue system verging upon free trade.“If the Southern Confederation is allowed to carry out a policy by which only a nominal duty is laid upon imports, no doubt the business of the chief Northern cities will be seriously injured thereby.”
All of that "preserving the Union" bullsh*t was just a smoke screen for their real reasons. The South was a cash cow, and the North wanted that money to keep coming their way. If the South was unproductive or relatively worthless territory, they would have said "fine. Leave." As they did with Cuba when we had it.
So yes, they killed 600,000 men in an evil effort to keep the money rolling in from slavery, they then *LIED* about the reasons they went to war so as to save face and misdirect people regarding the very evil thing that they did.
Rubes are still buying their propaganda.
