How did Zeus resolve the kidnapping of persephone?

Zeus resolved the kidnapping of Persephone by mediating between Hades, who had taken her to the Underworld, and Demeter, Persephone's mother, who was devastated by her daughter's absence. He mandated that Persephone spend part of the year with Hades in the Underworld and the other part with Demeter on Earth. This arrangement created the cycle of the seasons, explaining the growth and dormancy of crops. Thus, Persephone became the queen of the Underworld while also maintaining her connection to the earth and her mother.
