The Trojan War began after Paris, a Trojan prince, judged Aphrodite as the fairest goddess and received Helen, the beautiful wife of Menelaus, as a prize. This led Menelaus and his brother Agamemnon to launch an attack on Troy with their armies to retrieve Helen. The war lasted for 10 years and featured notable figures on both sides, including Hector and Achilles, until the Greeks devised the Trojan Horse trick to infiltrate and burn Troy, ending the war.
