ˌTrojan ˈWar, the BrE AmE noun
a war which is said to have been fought between the Greeks and the Trojans because the Trojan prince Paris had carried off Helen, wife of Menelaus, a Greek king. The war was won by a trick in which Greek soldiers, hidden inside a wooden model of a horse, were taken into Troy by the Trojans who thought that the horse was a gift. Homer describes the Trojan War in his book The Iliad .
