Hungary is a mess (sorry) You can't split amomg comitat borders - Zemplen fro example has Slovak majority in the north, Ruthenes in the middle and Hungarians uin the south.
Szekely is also a problem - should be considered Hungarian, but unliked to other "hungarian" Parts of Hungary.
Rebellion - that one was just put down (1848/49) - the premise is to hurt the Hungarians
