Prussia had an insurmountable ammount of luck in the Seven Years’ War, it’s no wonder that its survival is called the “Miracle of the House of Brandenburg”. Had they been defeated, we’d see a partition of its territories between its overwhelmingly numerous enemies.
East Prussia goes to Russia, with free access from Poland.
Pomerania goes to Sweden.
Silesia goes to Austria, as the austrians had lost the territory before and wanted it back
badly.
A rump Margraviate of Brandenburg remains, with shame on its face.
Hanover may be occupied by Austria and France, though i’m unsure of its fate after Britain is defeated.
With Prussia out of the equation, France can concentrate its army into naval operations, shipping them over to fight in the north american theatre. This means a survival of french Louisiana and Canada. With the threat of french colonist invasion still relevant, the thriteen colonies don’t see their reparation-taxation as invalid, and consider seceding from the british empire as too risky. Thus, no US.
Without the massive war reparations and economic depressions, the french revolution never happens, and french monarchism remains strong.
