Final answer:
Aphrodite supported the Trojans in the Trojan War after Paris of Troy chose her as the fairest goddess, promising him the love of Helen, the catalyst for the war.
Step-by-step explanation:
Aphrodite supported the Trojans during the Trojan War. The goddess of love and beauty was persuaded to take their side after Paris, the prince of Troy, awarded her the prize for beauty in a contest between the goddesses. This event is famously known as the Judgment of Paris, where Aphrodite promised Paris the love of the most beautiful woman in the world, Helen, who was already married to the Greek king Menelaus. Aphrodite's support of the Trojans led to the initiation of the war after Paris abducted Helen with Aphrodite's help.
