The Kingdom of Illyria was a titular crown land of the Austrian Empire from 1816 to 1849, the successor state of the Napoleonic Illyrian Provinces, which were reconquered by Austria in the War of the Sixth Coalition. It was established according to the Final Act of the Vienna Congress. Its administrative centre was in Ljubljana (officially German: Laibach)
Upon the Revolutions of 1848, the kingdom was dissolved and split into the Austrian crown lands of Carniola, Carinthia, and the Austrian Littoral.
