Isagoras

Isagoras (Greek: Ἰσαγόρας), son of Tisander, was an Athenian aristocrat in the late 6th century BC.

He had remained in Athens during the tyranny of Hippias, but after Hippias was overthrown, he became involved in a struggle for power with Cleisthenes, a fellow aristocrat. In 508 BC he was elected archon eponymous, but Cleisthenes opposed him, with support from the majority of the population. Isagoras requested support from the Spartan king Cleomenes I, an old friend who had earlier been given hospitality by Isagoras. According to Herodotus, Cleomenes had had an affair with Isagoras' wife.
