The challenge is to create the conditions for a civil war in a surviving Second French Empire. By surviving, I mean the civil war must be after 1870 (preferably in the 20th century) and there must be a POD involving the survival of the Second French Empire. Explain who the combatant sides would be ideologically, what would be the main issues they would be fighting over, what their goals would be, and where the geographical bastions of support would be. Points for creativity.
