The Greeks fought a ten-year war against the Trojans, known as the Trojan War. This conflict was famously depicted in Homer's epic poems, the "Iliad" and the "Odyssey." The war began over the abduction of Helen, the wife of Menelaus, by Paris of Troy, leading to a coalition of Greek city-states led by Agamemnon to besiege the city of Troy.
