The Trojan War, in Greek mythology, was a war between the Greeks and the people of Troy. The war began when the Trojan prince Paris captured Helen, the wife of Menelaus of Sparta. When Menelaus demanded the Trojan prince to return her, he refused. Menelaus then told his brother Agamemnon to lead an army against Troy. At Aulis, troopships gathered, led by some of the greatest Greek heroes. Including Achilles, Patroclus, Diomedes, Odysseus, Nestor, and two warriors named Ajax. When the winds came, the fleet set sail for Troy. For nine years the Greeks destroyed Troy's surrounding cities, but the city itself, was being protected and commanded by Hector and other sons of the royal family. Finally, after years of planning the Greeks built a large hollow wooden horse where a small group of them were concealed. The other Greeks appeared that they left, leaving behind only the horse and Sinon, who persuaded the Trojans, to take the horse into the city walls. At night the Greeks returned and their companions crept out of the horse. They opened the city gates, and Troy was destroyed. The gods took great interest in the war. Poseidon, Hera, and Athena aided the Greeks, while Aphrodite and Ares favored the Trojans. Zeus and Apollo, although frequently involved in the action of the war, remained impartial.
