This war is the most important in Greek mythology, and has been narrated through works of Greek literature, most notably Homer's Iliad. The war originated from a quarrel from the goddesses Hera, Athena and Aphrodite, after Eris, the goddess of strife and discord gave them a golden apple, also known as the Apple of Discord, which is only for the fairest. Well, after that, Zeus, the god of thunder and rain, sent the goddesses to Paris, who said that that, Aphrodite, should be given the golden apple as she was the fairest. Then, Aphrodite, in return, made Helen, the most beautiful women of all and wife of Menelaus, fall in love with Paris, who took her to Troy. Agamemnon, king of Mycenae and the brother of Helen's husband Menelaus, led an expedition of Achaean troops to Troy and besieged the city for ten years because of Paris' insult.
After the death of many heroes, including the Achaeans Achilles and Ajax, and the Trojans Hector and Paris, the city fell to the ruse of the Trojan horse. The Achaeans slaughtered the Trojans(except for some women and children whom they kept or sold as slaves) and desecrated the temples, thus earning the gods' wrath. Few of the Achaeans returned safely to their homes and many found colonies in distant shores.
