Gorizia and Gradisca
With the Treaty of Schönbrunn in 1809, Napoleon formed the short-lived Illyrian Provinces from the annexed territories in Carniola, Carinthia, Croatia, Gorizia and Gradisca, and Trieste. The Final Act of the 1815 Congress of Vienna restored the Illyrian Provinces to the Austrian Empire. Carniola then formed the central part of the territory of the Austrian Kingdom of Illyria, whose capital was also Ljubljana, including the Carniolan and Carinthian duchies as well as the Austrian Littoral with Gorizia and Gradisca, the Margraviate of Istria and the Imperial Free City of Trieste.
