The challenge here is for the Holy Roman Empire to collapse as a result of the 30 Years' War. How might this happen? Could a bungled handling if the Bohemian Revolt by the Empire lead to a deadlocked electoral college? Could the Siege of Vienna have gone better for the protestant side? Could Sweden have avoided war with Poland, allowing them to intervene when the Danes did? Could the survival of Gustavus Adolphus in Lutzen have brought the Swedes to Munich, or even Vienna?
