Let's say that Greater Germany (including Austria) is united sometime between 1848 and 1880. Since it involves Austria, a Hungarian Empire is likely left behind, no? Well, after everything is settled, how would the Hungarian and German empires relate to one another? Would the Germans and Hungarians most likely be allies, neutral to one another or enemies?
(and yes, I ask this question because I'm thinking of reworking my 1848 TL, but this is also out of general curiosity).
