22nd century BC
Pelasgians — a group of the most ancient pre-Greek tribes inhabiting the southern part of the Balkan Peninsula, the extreme northwest of Anatolia, the islands of the Aegean Sea, the predecessors of the Greeks in the territory of Hellas. At present, it is impossible to precisely identify the Pelasgian tribe chronologically, geographically, or linguistically. This is explained by the contradictory nature of statements about the Pelasgians in written sources and the complete absence of any remains of their material culture. According to most researchers, the Indo-European Pelasgians played a significant role in the ethnic formation of the Greeks.
The Pelasgians belonged to haplogroups I2, E1b1b, T, and G2a. E-V13 and T possibly arrived from the Levant and Anatolia during the Early Neolithic period, around 6500 BC. [Maciamo Hay 2008]
