Who was a populist politician and the effective ruler of Athens when Admetus was King of the Molossians?
Themistocles Themistocles ( ; Greek: Θεμιστοκλῆς "Themistoklẽs"; "Glory of the Law"; c. 524–459 BC) was an Athenian politician and general. He was one of a new breed of non-aristocratic politicians who rose to prominence in the early years of the Athenian democracy. As a politician, Themistocles was a populist, having the support of lower-class Athenians, and generally being at odds with the Athenian nobility. Elected archon in 493 BC, he convinced the polis to increase the naval power of Athens, a recurring theme in his political career. During the first Persian invasion of Greece he fought at the Battle of Marathon (490 BC) and was possibly one of the ten Athenian "strategoi" (generals) in that battle.
Cleon of Sicyon Cleon ( ; Greek: Κλέων "Kleon", ] ) was a tyrant of the ancient Greek city-state of Sicyon in the 3rd century BC. He came to power as commander of the Macedonian garrison after the conquest of the city by Demetrius Poliorcetes in 303/302 BC. Cleon governed Sicyon for some twenty years until he was assassinated. On his death he was followed by two more tyrants, Euthydemus and Timocleidas, who ruled jointly until they were expelled by a democratic revolt.
