People who haven't studied the Civil War have no idea how close the Confederate States came to achieving independence recognized by England and France. If Gettysburg had went to the south both France and England would have done so
England's disdain for slavery and the cultivation of Egyptain cotton made intervention in the war unlikely.
The Confederacy had some allies in France as well but military aid seemed unlikely as they were too busy trying to rebuild on an Empire at the expense of Mexcio. It didn't turn out as they planned. lol
