In this alternate history, the POD is that Bismark decides not to go easy on Austria during the Austro-Prussian War, and makes the peace terms more like those in Franco-Prussian War. Because of this, Austria collapses, with the new German Federation taking over most of Austria and Styria, and Italy gaining Venezia in return for helping them. The Hungarians quickly form their own nation, the Hungarian Empire, out of the remaining empire. Immediately separatists rise up. They put down all of them except for the Czech Separatists. The result of the war: A much larger German power, a Hungarian Empire and a Czech Republic. I'll take it from there, and we'll see how it goes.
