The Trojan war.

Athena, in part, started the Trojan War. The war originated from a quarrel between the goddesses, Aphrodite, Hera, and Athena.
Aphrodite is the enemy of Athena because once there was a beauty contest between Hera, Aphrodite, and Athens. Paris an immortal and the prince of Troy was told to give a golden apple to the fairest of them all by Zeus. Paris of course chosen Aphrodite because she was the goddess of love and the mos beautiful goddess. this sparked and rivalry between Athena, and Aphrodite.. Hope this helps :)
Aphrodite
The war was started as a result of a quarrel between the goddesses Athena, Hera, and Aphrodite. Athena also helped Achilles in some battles by tricking his opponents.
Athena didn't like the Trojans because of a contest between her, Aphrodite, and Hera. Paris, a prince of Troy, had to pick the most beautiful out of the three goddesses and he picked Aphrodite. This caused Athena to hold a grudge against the Trojans.
Hera and Aphrodite are the goddesses she fought
it wasnt aphrodite it was athena because she was so beautiful, she got raped.
Athena
There was a rivalry -not 'hate - between Aphrodite, goddess of love, Athena, goddess of wisdom, and Hera, the Queen of the gods; it escalated at the point of the golden apple of Discord.
Aphrodite won the Judgment of Paris, and Athena was jealous
Athena was aphrodite's sister
In Greek mythology, Aphrodite and Athena had a rivalry due to their different domains and characteristics. Aphrodite represented love and beauty, while Athena represented wisdom and warfare. Their opposing attributes sometimes led to conflict, such as in the story of the Trojan War when they supported different sides.
