Eris, the goddess of discord, was not invited to the party being held on Mount Olympus for all the gods and goddesses; therefore, she brought a gift for her revenge: a golden apple. After offering it to the "fairest," Aphrodite, Athena, and Hera all claimed it as their own.
The prince of Try, Hermes, was sent to decide who would be receiving the golden apple. Each woman offered a reward for choosing them: Hera offered power, Athena bribed him with winning wars, and Aphrodite promised him the most beautiful woman in the world.
As a result of choosing Aphrodite, she was presented the golden apple, and Pairs kidnapped Helen, the wife of the Spartan king. The Trojan war began.
It was nearly ten years later, and the Greeks had traveled to Trojan and unsuccessful at besieging Troy. Odysseus, a young warrior, decided to build a hollow wooden horse and left it at the gates of Troy.
That night, the Trojans accepted the horse into their city's walls, unaware of the hidden Greeks. The warriors exited the horse and entered into the Trojan city. They destroyed Troy and claimed victory of the Trojan War.
