When an island occupied by them began to overpopulate a man with everrything necessary for subsistence was chosen and families that accompanied him looked for a territory in wich they settled. Once were established they created their own laws and were engaged in trade as a way of life and there was no rivalry between them, that is, all greeks lived from trade and once they left and occupied new territory were independent. They created a new state that had its own king. Although they had the same religion and the same origin and spoke the same language they were different.
