Austrian Empire The Austrian Empire (Austrian German: "Kaiserthum Oesterreich" , modern spelling "Kaisertum Österreich ") was a Central European multinational great power from 1804 to 1867 created by proclamation out of the realms of the Habsburgs. It was the third most populous empire after Russia and France, as well as the largest and strongest country in the German Confederation. Geographically, it was the second largest empire in Europe after the Russian Empire (621,538 square kilometres [239,977 sq mi]). Proclaimed in response to the First French Empire, it overlapped with the Holy Roman Empire until the latter's dissolution in 1806. The "Ausgleich" of 1867 elevated Hungary's status. It became a separate entity from the Empire entirely, joining with it in the dual monarchy of Austria-Hungary.
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.
