As USA Today notes, the social media firestorm over the upcoming HBO series “Confederate” is burning unabated. The series is set in a world where the Confederates won the Civil War and slavery still exists. HBO will probably proceed with the show despite the controversy, but in case it does not, here follow some Alternate History show ideas, based on published books.

‘Southern Victory’ by Harry Turtledove

This book series also depicts a Confederate world, with alternate versions of World War I and World War Ii. The difference in the scenario and the “Confederate” one is that slavery has been abolished, partly due to pressure brought to bear by the South allies Britain and France and partly because the system makes no economic sense.
