Who was a populist politician and the effective ruler of Athens when Admetus was King of the Molossians?
Admetus of Epirus Admetus (Greek: Αδμητος ) (before 470-430 BC) was a Greek king of the Molossians at the time that Themistocles (524–459 BC) was the effective ruler of Athens. When Themistocles was in control of Athens, Admetus had opposed him, but without any rancour.
Cleisthenes Cleisthenes ( ; Greek: Κλεισθένης , "Kleisthénēs"; also Clisthenes or Kleisthenes) was a noble Athenian of the Alcmaeonid family. He is credited with reforming the constitution of ancient Athens and setting it on a democratic footing in 508/7 BC. For these accomplishments, historians refer to him as "the father of Athenian democracy." He was the maternal grandson of the tyrant Cleisthenes of Sicyon, as the younger son of the latter's daughter Agariste and her husband Megacles. Also, he was credited with increasing the power of the Athenian citizens’ assembly and for reducing the power of the nobility over Athenian politics.
