WI prussia had retained the territory gained in the three partitions of the PLC?, you can pick any PoD necesary to do it. What would be the consequences of this development? Could it destabilize the country enough for it to lose relevance to Austria in the German Unification? Will it be dragged down by too many internal issues? Will the policies of the nation change too much eastwards to be recognizable? With the PoD you chose, what would happen to the rest of the PLC? Any chance of it being restored in any meaningful way?
