What were the two opposing armies in the Trojan war?

The two opposing armies in the Trojan War were the Achaeans (Greeks) and the Trojans. The Achaeans, led by notable figures such as Agamemnon and Achilles, sought to reclaim Helen, the wife of Menelaus, who had been taken by Paris of Troy. The Trojans defended their city, with prominent leaders like Hector and Priam. This legendary conflict is central to Homer's epics, notably the "Iliad."
