HIPPARCHUS and HIPPIAS, the sons of Pisistratus, succeeded their father in the tyranny of Athens. Strictly speaking the right of government belonged to Hippias, who, on the express testimony of Thucydides (which, however, is at variance with that of other historians), was the elder of the two, but the brothers seem to have administered public affairs conjointly with an extraordinary unity of purpose. They carried out the principles of their father, and the period of their sway, at least till the murder of Hipparchus, B.C. 514 (see Harmonius), was looked upon by the people of Athens as a sort of golden age. After his brother's death Hippias' character underwent a total change. He became a "tyrannus" of the worst type, and ruled with such intolerable severity that he was at last obliged to fly from Attica to escape the fury of the many enemies he had raised about him. After various wanderings, he took refuge in the court of Darius, king of Persia, and instigated that monarch to the invasion of his native country. He joined the expedition sent out under Datis and Artaphernes, and accompanied it to the field of Marathon, after which all trace of him in history is lost.
