There were two parts of the Greek-speaking world at this time which did not suffer from revolution and did not seek to impose rule over the city states. In Epirus there were three clusters of tribal states, called Molossia, Thesprotia and Chaonia[...]the other part of the Greek-speaking world extended from Pelagonia in the north to Macedonia in the south. It was occupied by several tribal states, which were constantly at war against Illyrians, Paeonians and Thracians.
