In the middle of the 6th century three were the parties that claimed the power: Plains (owned large acres of land), the Coastals (artisans and seamen) and the Diakrioi (mountaineers and farmers). The chief of the former ones was the nobleman Pisistratos, who became tyrant in 561 b.c. Although he was taken down twice, he achieved to establish another tyranny in 540 b.c, which he maintained up to his death in 528 b.c. Pisistrato’s tyranny encouraged the villagers and stopped the adversities between the fighting sides, helping the economic growth of the city. During this period the Athenian trade reached up to Italy, Egypt and the Black Sea, while Athens was enriched with the Enneakrouno, the Market, the Olympeio and the Ekatompedo in Acropolis.
