Explanation:

Zeus had given Thetis, the sea nymph as a wife to Peleus and they held a wedding ceremony for them to which they did not invite Eris, the goddess of discord.

She was not pleased and made a golden apple which was inscribe For the most beautiful and threw it into the wedding thereby causing the 3 goddesses Athena, Aphrodite, and Hera to be pitted in competition against each other.

Zeus did not want to get involved and told them to ask a human who was the most beautiful and thus deserving of the apple. The human turned out to be Paris who asked them what they would do for him.

Aphrodite promised him the most beautiful woman in the world and won the apple. To fulfil her promise she made Helen (the most beautiful woman in the world then) who was already married to Menelaus, fall in love with Paris and then aided their escape to Troy.

Menelaus and his brother then gathered an army and attacked Troy.
