King Oenomaus was a figure from Greek mythology, known as the king of Pisa in Elis. He was famous for his tragic fate, which involved a deadly chariot race against suitors who sought to marry his daughter, Hippodamia. Oenomaus was said to be a skilled charioteer, and he challenged each suitor to a race, killing them if they lost. His story is closely linked to the hero Pelops, who ultimately defeated Oenomaus in a race, leading to the king's death. This event marked the beginning of Pelops' rise to power and the establishment of the Peloponnesian dynasty.
