Something I never learned in school: during the Civil War, there was a militant force in Missouri determined to make it Confederate. The Missouri State Guard, led by Stirling Price, fought the Union for quite a while, even occasionally winning.
So, the thought came to me: what would be the result of a more successful Missouri State Guard? What if the Union had never managed to defeat Price, and Missouri had ended up in the Confederacy? Would there have been any noticeable difference?
