Since so little is known about the early Macedonians, it is hardly strange that in both ancient and modern times there has been much disagreement on their ethnic identity. The Greeks in general and Demosthenes in particular looked upon them as barbarians, that is, not Greek. Modern scholarship, after many generations of argument, now almost unanimously recognises them as Greeks, a branch of the Dorians and ‘NorthWest Greeks’ who, after long residence in the north Pindus region, migrated eastwards. The Macedonian language has not survived in any written text, but the names of individuals, places, gods, months, and the like suggest strongly that the language was a Greek dialect. Macedonian institutions, both secular and religious, had marked Hellenic characteristics and legends identify or link the people with the Dorians. During their sojourn in the Pindus complex and the long struggle to found a kingdom, however, the Macedonians fought and mingled constantly with Illyrians, Thracians, Paeonians, and probably various Greek tribes. Their language naturally acquired many Illyrian and Thracian loanwords, and some of their customs were surely influenced by their neighbours[...] To the civilised Greek of the fifth and fourth centuries, the Macedonian way of life must have seemed crude and primitive. This backwardness in culture was mainly the result of geographical factors. The Greeks, who had proceeded south in the second millennium, were affected by the many civilising influences of the Mediterranean world, and ultimately they developed that very civilising institution, the polis. The Macedonians, on the other hand, remained in the north and living for centuries in mountainous areas, fighting with Illyrians, Thracians, and amongst themselves as tribe fought tribe, developed a society that may be termed Homeric. The amenities of city-state life were unknown until they began to take root in Lower Macedonia from the end of the fifth century onwards.
