The Neolithic Revolution reaches Europe by way of Greece and the Balkans, beginning in the 7th millennium BC. Some Neolithic communities in southeastern Europe, such as Sesklo in Greece, were living in heavily fortified settlements of 3,000-4,000 people. The Greek Neolithic ends with the arrival of the Bronze Age from Anatolia and the Near East, by the end 28th century BC (early Helladic period).
In about 1900 BC, the Indo-Europeans overran the Greek peninsula from the north and east. These Indo-Europeans, known as Mycenaeans, introduced the Greek language to present-day Greece.
