Let's say Frederick II managed to conquer the Duchy of Silesia in the War of the Austrian Succession like he attempted to. What would that look like? I suppose it would turn Prussia into a larger power than OTL and maybe even help them in supplanting the Austrians as the prime power in the HRE. Also, surely Maria Theresa wouldn't just let go of it easily and she'll probably try to regain it, though I'm not sure the British would provide much help for that. What would the loss of this region mean for Austria and how would it benefit the Prussians? How would things look on the diplomatic and military scene of Europe?
