Modern archaeological excavations in Greece in the second millennium BC and early 1 millennium BC reveal that human beings have lived in the Greek mainland since the Paleolithic Age. At the end of 3000 BC, bronze culture appeared in Crete, and at the beginning of 2000 BC, there were countries and characters.
Around 2000 BC, some Greek-speaking tribes began to settle in the Greek peninsula.
In the middle and late 2000 BC, the Greeks established Mycenae, Tirins, Pailos and other small countries, which had written languages and created splendid Mycenae civilization.
From the middle of the second millennium BC, the Greeks gradually expanded to the Aegean islands (including Crete).
Legend has it that it happened in Troy, Asia Minor.
The war may have happened in the second half of BC13rd century, or it may have happened in the early stage of Greek expansion in BC12nd century.
(See Crete Civilization and Mycenae Civilization)
Mycenaean civilization gradually declined within one or two hundred years after12nd century BC.
Some Greek-speaking tribes living at the end of primitive society entered the Greek peninsula from the north, which led to the migration of many Greek tribes and tribes in Thessalonica and its south in different directions.
Countries, writing and magnificent palaces have disappeared, followed by the "Homeric Age" in which social organizations and lifestyles at the end of primitive society ruled the Greek peninsula, Aegean islands and the areas inhabited by Greeks in Asia Minor.
