Jazyges, a tribe belonging to the numerous nationalities comprehended during the earlier period of the Roman empire under the name of Sarmatians, who dwelt originally on the northern shores of the Black sea and sea of Azov. In the time of the emperor Claudius, being pressed by their neighbors, they divided into three bodies, which established themselves respectively on the Don, between the Dnieper and the Dniester, and in the marshy region between the Theiss and the Danube. The two former divisions became tributary to the Goths; the third, because of their position between Pannonia and Dacia, lived under the protection of Rome, and were called Jazyges Metanastce, or transplanted. Their name disappeared in the great invasion of the Magyars. They reappeared as a Magyarized tribe (Hun. Jaszok, bowmen) at a later period, when their possessions between the Danube and Theiss formed a separate central district of Hungary under the name of Jazygia (Jaszsag). This fertile region was united with Cumania, and down to 1848 was under the special administration of the palatine, who also bore the title of captain of the Jazyges and Cumanians. It embraces among others the towns of Jasz-bereny, the capital of the united districts, Arok-Szallas, and Apathi, and has an area of 400 sq. m., and a population of 60,000 (area of Jazygia and Cumania together, 1,825 sq. m.; pop", in 1870, 215,526).
