In the early 4th century BC (c. 370-368 B.C), the Molossian officials were the king, the "prostatai" () literally meaning "protectors" like most Greek tribal states at the time, the "grammateus" () meaning "secretary", the "hieromnemones" (Greek: ἱερομνήμονες) literally meaning "of the sacred memory" and the ten "damiourgoi" (Greek: δημιουργοί) literally meaning "creators"; one each for the ten tribes which made up the Molossian group (Arctanes, Tripolies, Celaethoi, Genoaei, Ethnestes, Triphyles, Omphales, Onopernoi and Amymnoi. Once a year the king of the Molossians, having sacrificed to Zeus Areios as god of war, made a formal exchange of oaths with the Molossian tribes, swearing to rule in accordance to the laws. A later inscription, dating probably within the reign of Neoptolemus (shortly before c. 360 B.C.), named the Molossian state as "koinon of the Molossians" and mentioned not only the previous ten tribes but also additional five (among them the Orestae and the Paroroi) — from the region of north Pindus — a region which had evidently entered Molossian rule. The state officials now were: the king, the prostates, the secretary (grammateus) and a board of fifteen synarchontes (), literally meaning "co-rulers", instead of the earlier ten damiourgoi. The king also held the military command as an 'Aeacidae'; a descendant of Achilles.
