Okay, guys, much as I am enjoying the spirited debate, this seems to be (because of a comment I made) descending a into Hohenzollern vs Wittelsbach complaint. If we want that we can point out the rivalry between the Wettins and the Hohenzollerns was what kickstarted the reformation - Albrecht of Brandenburg having to raise taxes in order to be elected to the Archbishopric of Mainz - blah-blah.
Now, what I'm asking is what if Prussia isn't the (only) premier power in Germany in 1815. AFAIK, her army was pretty much run to seed when Wilhelm I tried to bring in his reforms, so, this is the situation it develops from: Prussia gets the Rhineland and Swedish Pomerania, nothing else. Saxony stays its 1810/1814 size, and because it jumps ship more/less at the same time as Bavaria gets similar compensation at alt-Vienna (I'm thinking Saxony gets parts of Silesia, maybe - partitioned with Austria, much like Bavaria did a couple territory swaps with Austria). Saxony and Bavaria are likely both to be regarded with suspicion but OTL even that didn't seem to stick very long. How does this affect German Unification? There's 30 Years between 1815 and 1848, in which a lot can change - Friedrich Wilhelm IV can have a son, Wilhelm I can marry Elisa Radziwill, Franz Josef can marry a Prussian princess like he wanted to (and those are just in the familial matters). - so how might this affect matters.
What might Saxony get (if any) as compensation? And if Bavaria gets but Saxony doesn't, can/will Saxony kick up a fuss about it?
