 The creator of the Tetrarchy Diocletian and his fellow Tetrarchs Maximian, Constantius Chlorus (father of the first Christian emperor Constantine) and Severus II were also of Illyro-Roman background.There are scholars who note that the military spirit and Latin education of the Roman emperors with Illyrian stock often conflicted with the contemporary ideals of an ancient culture, which is based on classical Greek.During the Middle Ages, the descendants of the Illyro-Romans have influenced the growth of the Balkan peninsula.
