Who Started the Trojan War?

Legend has it that the Trojan War was caused by the wife of the King of Sparta being stolen by Paris of Troy. In Greek mythology, this was said to have been caused by the Gods, who, after a quarrel, sent the Apple of Discord to Paris, naming him the fairest. In exchange for this title, Aphrodite made Helen, the most beautiful woman in Menelaus, fall in love with Paris.
