The Judgement of Paris

Apollodorus Epitome 3:

Afterwards Alexander abducted Helen, in accordance, some say, with the will of Zeus, so that his daughter would become famous for having brought Europe and Asia to war, or, as others have said, to ensure that the race of demigods would be raised to glory.

For one of these reasons, Eris threw an apple in front of Hera, Athene and Aphrodite as a prize for the most beautiful, and Zeus instructed Hermes to take them to Alexander on Mount Ida, to be judged by him for their beauty. They promised to give Alexander gifts; Hera promised him universal dominion if she were preferred above all other women, while Athene offered victory in war, and Aphrodite the hand of Helen.

He decided in favour of Aphrodite, and sailed to Sparta with ships built by Phereclos. He was entertained for nine days by Menelaos, and on the tenth, when Menelaos departed for Crete to celebrate the funeral of his maternal grandfather Catreus, Alexander persuaded Helen to go away with him.
