Events that Led to the Civil War: Slavery as an Economic Engine Not a Moal Isssue

[Nope]

Of course it didn't.....but we like our history simple (and we like to imagine ourselves wearing the white hats), so "war to end slavery" stuck.

Sadly, we all like simple history where we are the good guys.

Mississippi's Declaration of Secession is pretty straight forward as to the state's reason for leaving the union

Our position is thoroughly identified with the institution of slavery-- the greatest material interest of the world. Its labor supplies the product which constitutes by far the largest and most important portions of commerce of the earth. These products are peculiar to the climate verging on the tropical regions, and by an imperious law of nature, none but the black race can bear exposure to the tropical sun. These products have become necessities of the world, and a blow at slavery is a blow at commerce and civilization. That blow has been long aimed at the institution, and was at the point of reaching its consummation. There was no choice left us but submission to the mandates of abolition, or a dissolution of the Union, whose principles had been subverted to work out our ruin.
