Cypselus (or Kypselos) (in Greek, ) was the first tyrant of Corinth in the 7th century BC. With increased wealth and more complicated trade relations and social structures, Greek city-states tended to overthrow their traditional hereditary priest-kings; Corinth, the richest archaic polis, led the way. Like the signori of late medieval and Renaissance Italy, the tyrants usually seized power at the head of some popular support. Often the tyrants upheld existing laws and customs and were highly conservative as to cult practices, thus maintaining stability with little risk to their own personal security. As in Renaissance Italy, a cult of personality naturally substituted for the divine right of the former legitimate royal house.
