Classical antiquity

Greek sources of the Classical period acknowledge Indigenous people whom they referred to as " Pelasgians ". Ancient writers saw these people either as the ancestors of the Greeks, or as an earlier group of people who inhabited Greece before the Greeks. The disposition and precise identity of this former group is elusive, and sources such as Homer, Hesiod and Herodotus give varying, partially mythological accounts. Dionysius of Halicarnassus in his book, Roman Antiquities, gives a synoptic interpretation of the Pelasgians based on the sources available to him then, concluding that Pelasgians were Greek. Greco-Roman society flourished between 330 BCE and 640 CE and undertook successive campaigns of conquest that subsumed more than half of the known world of the time. But because preexisting populations within other parts of Europe at the time of classical antiquity had more in common – culturally speaking – with the Greco-Roman world, the intricacies involved in expansion across the European frontier were not so contentious relative to Indigenous issues.
