Pelasgian

n. member of the ancient people that inhabited Greece and the Aegean Islands

The name Pelasgians (Ancient Greek: Πελασγοί - Pelasgoí, s. Pelasgós) was used by some ancient Greek writers to refer to groups of people who preceded the Hellenes. Some of these people still dwelt in several locations in mainland Greece, Crete, and other regions of the Aegean, as neighbors of the Hellenes, into the 5th century BC. However, other ancient Greek and Roman writers describe them as Greeks. Even though ancient Greek references to the Pelasgians are confusing, many Greek writers agreed that Pelasgians had spoken a "barbaric" or "unsophisticated Greek" language. No secure archaeological connection of Pelasgians with a Late Neolithic site has been made.
