Who were the main contestants and enemies in the Trojan war?

The main contestants in the Trojan War were the Greeks, led by notable figures such as Agamemnon, Achilles, and Odysseus, and the Trojans, led by King Priam and his son Hector. The conflict arose primarily over the abduction of Helen, the wife of Menelaus, by Paris of Troy. Key enemies included Achilles, who fought fiercely against Hector, and the cunning Odysseus, who devised the strategy of the Trojan Horse that ultimately led to Troy's downfall. The war is primarily recounted in Homer's "Iliad."
