Kingdom of Slavonia The Kingdom of Slavonia (Croatian: "Kraljevina Slavonija" ; German: "Königreich Slawonien" ; Latin: "Regnum Sclavoniae" ; Hungarian: "Szlavón Királyság" ) was a province of the Habsburg Monarchy and the Austrian Empire that existed from 1699 to 1868. The province included northern parts of present-day regions of Slavonia (today in Croatia) and Syrmia (today in Serbia and Croatia). The southern parts of these regions were part of the Slavonian Military Frontier, which was a section of the Military Frontier.
