In 1848, the Hungarian Revolution is a success and a Hungarian Kingdom (Republic?) is established in the Pannonian Basin. Galicia and Bukovina become a separate Hapsburg Kingdom of Galicia and Croatia-Slavonia, Dalmatia, and Burgenland remain Austrian.
Austria, now focused almost entirely on Germany, pushes for German unification under Austrian domination. In the Austro-Prussian War of TTL, Austria defeats Prussia, annexes Silesia, allows for Prussian dismemberment (Hapsburg principalities established in Schleswig-Holstein, North Rhineland, and South Rhineland to compensate the dispossessed Hapsburg of Italy, and Saxony returning to Napoleonic borders), and is without a doubt top dog in the German Empire.
What would be the structure and culture of an Austrian Germany versus a Prussian one?
