ILLYRIA, ILLYRIS, or ILLYRI CUM, a name anciently applied to all the countries on the east coast of the Adriatic. In the 4th century E. C., the n. portions of Illyria were visited by the Gauls, who expelled the natives, and drove them to the S. Philip II., King of Macedon, waged war with the Illy rians 359 B. C.; and the Romans sent an army against them, and compelled them to sue for peace, 232 B. c. The second Illyrian War commenced 229 B. c., and also terminated in favor of the Romans. The Dalmat revolted from the Illyrians 180 B. c., and formed the independent state of Dalmatia, and the remaining country was reduced into a Roman province by L. Anicius 168 B. C. It be came an imperial province 11 B. C. Dal matia, Carniola, and some neighboring countries, received the name of Illyrian Provinces by a decree issued by Na poleon I., Oct. 14, 1809. In 1815, these provinces were united as a kingdom to the Austrian empire, and some altera tions were made in its boundaries, es pecially by the restoration to Hungary of what had formerly belonged to it, and the annexation of the whole of Carinthia instead. The kingdom was divided into
the two governments of Laibach and Trieste, Laibach being the capital; which arrangement existed till 1849, when it was subdivided, for administrative pur poses, into the duchies of Carinthia and Carniola, and into the coast district, con taining the territory of Trieste, and the counties of Gorz, Gradiska, and Istria. By the terms of the Treaty of St. Ger main Carinthia remained to Austria, Carniola and Istria were given to Jugo Slavia, while Trieste, Gorz and Gra diska, now known as Gorizia and Gra disca, were assigned to Italy.
