The Austrian Empire (Austrian German: Kaiserthum Oesterreich, modern spelling Kaisertum :Osterreich) was a modern era successor empire centered on what is today's Austria and which officially lasted from 1804 to 1867. It was followed by the Empire of Austria-Hungary, whose proclamation was a diplomatic move that elevated Hungary's status within the Austrian Empire as a result of the Austro-Hungarian Compromise of 1867. The Austro-Hungarian Empire (1867 to 1918) was itself dissolved by the victors at the end of World War I and broken into separate new states. The term "Austrian Empire" is also used for the Habsburg possessions before 1804, which had no official collective name, although Austria is more frequent.
Francis II, Holy Roman Emperor (German language: Franz II, Heiliger Roemischer Kaiser) (Florence, 12 February 1768 - Vienna, 2 March 1835) was the last Holy Roman Emperor, ruling from 1792 until 6 August 1806, when he dissolved the Empire after the disastrous defeat of the Third Coalition by Napoleon at the Battle of Austerlitz.
