Compromise of 1867, Transleithania consisted of the Kingdom of Hungary including Hungary proper (which also included territories of the former Principality of Transylvania (Erdélyi Fejedelemség) and the former Voivodeship of Serbia and Banat of Temeschwar), the internally self-governed Kingdom of Croatia-Slavonia, and the free port of Rijeka (Fiume). The Military Frontier was under separate administration until 1873–1882, when it was abolished and incorporated into Hungary proper and the Kingdom of Croatia-Slavonia.

However, the new government faced severe economic problems and the growing restiveness of ethnic minorities.
