How was boundary of Hungary decided during 1867 Compromise?
I was looking at the subdivision of the Austrian Empire b/w 1816-1867 and Transylvania, Vojvodina and Croatia aren't part of Kingdom of Hungary.
There is Grand Principality of Transylvania, Voivodeship of Serbia and Banat of Temeschwar and Kingdom of Croatia and Slavonia.
I guess the Kingdom of Croatia and Slavonia still remain autonomous but why did Austria just give Transylvania and Vojvodina to Hungary instead of keeping it during compromise to have as much power as possible.
