Brief overview of Hades and Persephone?

Answer 1

Persephone was the daughter of Demeter, a goddess of growing things, and Zeus had promised Hades for Persephone as a wife - he then took the maiden when she was grown, unknowing that neither Persephone or Demeter had not agreed to the marriage promised to him; Persephone became his wife and Queen of the Underworld either by choice or Hades tricking her when she ate of the food of the Underworld. Doing so ensured that she must every year return to the Underworld.
