Pelops is a figure from Greek mythology, known as the son of Tantalus and the grandson of Zeus. He is famous for his role in the myth of the Chariot Race, where he competed against Oenomaus for the hand of Hippodamia. Pelops won the race with the help of Poseidon and a treacherous plan involving a chariot with wax wheels. After his victory, Pelops became the king of Elis and founded the Olympic Games in honor of his father. His legacy continued through his descendants, including Atreus and Agamemnon, who played significant roles in other myths, particularly in the Trojan War.
