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.
Flag of Prussia The state of Prussia had its origins in the separate lands of the Margraviate of Brandenburg and of the Duchy of Prussia. The Margraviate of Brandenburg developed from the medieval Northern March of the Holy Roman Empire, passing to the House of Hohenzollern in 1415. The Duchy of Prussia originated in 1525 when Albert of Brandenburg-Ansbach, a member of a cadet branch of the Hohenzollerns, secularized the eastern lands of the Teutonic Knights as a Polish fief. Prince-elector John Sigismund, Elector of Brandenburg, inherited the Duchy of Prussia in 1618, thus uniting Brandenburg and Prussia under one ruler in a personal union; the Elector's state became known as Brandenburg-Prussia. The Kingdom of Prussia formed when Elector Frederick III assumed the title of Frederick I, King in Prussia, on 18 January 1701.
