ancient region along the E coast of the Adriatic
An ancient region of the Balkan Peninsula on the Adriatic coast. Occupied in prehistoric times by an Indo-European-speaking people, the area became the Roman province of Illyricum after the final conquest of the Illyrians in 35–33 BC. The name was revived by Napoleon for the provinces of Illyria (1809–1815) and retained for the kingdom of Illyria, a division of Austria from 1816 to 1849.
From Ancient Greek Ἰλλυρία (Illuría).
