Why wasn't the Kingdom of Saxony annexed by expanding Prussia after the Austro-Prussian War of 1866, unlike other similarly significant kingdoms who also fought for Austria, like Hanover and Hesse-Kassel?
If Saxony had indeed been annexed by Prussia after being defeated in 1866, what would the ramifications be? How would the other Great Powers, the South German kingdoms, and the North German duchies then allied to Prussia react? If everything proceeds as OTL and the German Empire still forms, what would a Prussian Saxony entail for imperial politics, seeming as Berlin already pretty much dominated the country through the sheer size of its economy IOTL?
