Died 490 B.C.E.
Tyrant Of Athens

Revenge. One of the sons of Pisistratus, Hippias ruled Athens as a tyrant from 528 to 510 B.C.E. The city-state prospered under the early part of his reign, and Hippias was considered to be a patron of artists and craftsmen. However, following the assassination of his brother Hipparchus in 514, Hippias used severe measures against his political enemies. Four years later the Spartan king Cleomenes I invaded Attica and expelled Hippias and his followers. Taking refuge with the Persians, he returned to Greece with the army of Darius I in 490 and supposedly advised the landing in the bay of Marathon. He died at Lemnos soon afterward.
