The Illyrian Provinces was a short-lived autonomous province of the Napoleonic French Empire, established in 1809 on the territories along the north and east coasts of the Adriatic Sea, which had been conquered in the War of the Fifth Coalition. Its capital was established at Ljubljana (Laybach). The name "Illyrian" was used to refer to ancient Illyrian tribes who once lived in the area and constitutes a Neoclassicist relabeling of the Dalmatian coast, which was known as Illyria in antiquity.
