Why does Pluto take Persephone to his kingdom?

In Greek mythology, Pluto (Hades) takes Persephone to his kingdom because he falls in love with her and desires to make her his queen. After abducting her from the meadow where she was gathering flowers, he brings her to the Underworld, where he hopes to keep her with him. This act leads to the seasonal cycle, as her mother Demeter, the goddess of agriculture, grieves her absence, causing the earth to become barren during the months Persephone spends in the Underworld.
