Inês de Castro was a Galician noblewoman best known as lover and posthumously-recognized wife of King Peter I of Portugal. The dramatic circumstances of her relationship with Peter, which was forbidden by his father King Afonso IV, her murder at the orders of Afonso, Peter's bloody revenge on her killers, and the legend of the coronation of her exhumed corpse by Peter, have made Inês de Castro a frequent subject of art, music, and drama through the ages.
