イリュリア州
Trieste was occupied by French troops three times during the Napoleonic Wars, in 1797, 1805 and in 1809. Between 1809 and 1813, it was annexed to the Illyrian Provinces, interrupting its status as a free port and causing a loss of the city's autonomy; the municipal autonomy was not restored after the return of the city to the Austrian Empire in 1813. For the French, the Illyrian Provinces provided a military frontier against the remaining Austrian lands and a military base against the Turks, as well as providing distant endowments for Marshals of the Empire.
