The name of Illyria had by this time disappeared from history. In literature it was preserved, and the scene of Shakespeare's comedy, _Twelfth Night_, is laid in Illyria. Politically the name was revived in 1809, when the name Illyrian Provinces was given to Carniola, Dalmatia, Istria, Fiume, Görz and Gradisca, and Trieste, with parts of Carinthia and Croatia; these territories were ceded by Austria to Italy at the peace of Schönnbrun (14th Oct. 1809). The Illyrian Provinces were occupied by French troops and governed in the interest of Napoleon; the republic of Ragusa was annexed to them in 1811, but about the end of 1813 the French occupation ceased to be effective and the provinces reverted to Austria. The kingdom of Illyria, which was constituted in 1816 out of the crown-lands of Carinthia, Carniola, Istria, Görz and Gradisca, and Trieste, formed until 1849 a kingdom of the Austrian crown.

ILMENAU, a town and summer resort of Germany, in the grand-duchy of Saxe-Weimar, at the north foot of the Thuringian Forest, on the river Ilm, 30 m. by rail south of Erfurt. Pop. (1905) 11,222. The town, which stands picturesquely among wooded hills, is much frequented by visitors in the summer. It was a favourite resort of Goethe, who wrote here his _Iphigenie_, and often stayed at Gabelbach in the neighbourhood. It has a grand-ducal palace, a Roman Catholic and two Evangelical churches, a sanatorium for nervous disorders, and several educational establishments. Its chief manufactures are glass and porcelain, toys, gloves and chemicals, and the town has tanneries and saw-mills. Formerly a part of the county of Henneberg, Ilmenau came in 1631 into the possession of electoral Saxony, afterwards passing to Saxe-Weimar. See R.
