In OTL, upon the death of Emperor Charles VI, last of the direct Habsburgs, Frederick II, King in Prussia, decided to renege on the Pragmatic Sanction of 1713 and attacked the Habsburg Monarchy in the First Silesian War, which with the Second Silesian War formed part of the War of the Austrian Succession (as the third happened during the Seven Years' War).

Now, supposing some accident of history ensures that Frederick does not manage to acquire Silesia in this war (or wars), how would European history unfold?
