Harmodius (Greek: Ἁρμόδιος, Harmódios) and Aristogeiton (Ἀριστογείτων, Aristogeíton; both died 514 BC) were two lovers from ancient Athens. They became known as the Tyrannicides (τυραννοκτόνοι, tyrannoktonoi) after they killed the Peisistratid tyrant Hipparchus, and were the preeminent symbol of democracy to ancient Athenians.
