composed of small areas within the region of Illyria. Only the Romans ruled the entire region. The internal organization of the south Illyrian kingdom points to imitation of their neighbouring Greek kingdoms and influence from the Greek and Hellenistic world in the growth of their urban centres. Polybius gives as an image of society within an Illyrian kingdom as peasant infantry fought under aristocrats which he calls in Greek Polydynastae (Greek: Πολυδυνάστες) where each one controlled a town within the kingdom. The monarchy was established on hereditary lines and Illyrian rulers used marriages as a means of alliance with other powers. Pliny (23–79 AD) writes that the people that formed the nucleus of the Illyrian kingdom were 'Illyrians proper' or Illyrii Proprie Dicti. They were the Taulantii, the Pleraei, the Endirudini, Sasaei, Grabaei and the Labeatae. These later joined to form the Docleatae. The last known king of illyrians was King Ballaios who ruled over the city of Rhizon and surrounding areas after Roman occupation, from 167 BC until 135 BC. Rulers Enchelean-Taulantian rulers Galaurus: king of Taulantii. Unsuccessfully invaded Macedonia between 678–640 BC. Grabos I (5th century BC): attested on an Athenian inscription, he was very likely a person with great political responsibilities. He probably was the grandfather of Grabos II. Sirras (437–390 BC), ruler in Lyncestis. Grabos II (r. 358–356 BC): entered Athenian alliance to resist Philip's power in 356 BC. Pleuratus I (r. 356–335 BC): reigned near the Adriatic coast in southern Illyria. In a losing effort in 344 BC, tried to thwart Philip's advances in Illyria. Pleurias (r. c. 337/336 BC): Illyrian ruler who campaigned against Philip II about 337 BC. He is considered by some scholars as king of either the Autariatae, the Taulantii, or the Dardani. Some have suggested that he was the same as Pleuratus I; Pleurias is mentioned only in Diodorus (16.93.6), elsewhere unattested in ancient sources. Cleitus, son of Bardylis I (r. 335–295 BC): mastermind behind the Illyrian Revolt in Pelion of 335 BC against Alexander the Great. Glaucias: king of Taulantii. He aided Cleitus at the Battle of Pelion in 335 BC, raised Pyrrhus of Epirus and was involved in other events in southern Illyria in the late 4th century BC. Monunius I, (r. 290–270 BC): reigned during the Gallic invasions of 279 BC. He minted his own silver staters in Dyrrhachion. Mytilos, successor of Monunius I and probably his
