What if Prussia manages to stay indendant and isolated from the German states? If your POD is rather late, could Prussia leaves the North German Confederation? Would the other German states (excluding Austria and Prussia) unite under one state? If not, with the situation staying the same long enough, would Austria-Hungary absorb them? Or would Prussia be able to absorb them without creating a new state or implementing new laws that would decentralize Prussia? How would this affect the rest of the decades to come and a possible Great War? What would happen to Prussia and other German states from these events?
