Who married Inês de Castro?

Inês de Castro (Portuguese pronunciation: [iˈneʒ ðɨ ˈkaʃtɾu]; in Castilian: Inés; 1325 – 7 January 1355) was a Galician noblewoman and courtier, best known as the lover and posthumously recognized wife of King Pedro I of Portugal. The dramatic circumstances of her relationship with Pedro (at the time Prince of Portugal), which was forbidden by his father Afonso IV of Portugal, her murder at the orders of Afonso, Pedro's bloody revenge on her killers, and the legend of the coronation of her exhumed corpse by Pedro, have made Inês de Castro a frequent subject of art, music, drama and poetry through the ages.

Pietro Alfonso di Borgogna del Portogallo, detto il Giustiziere ("o Justiceiro"), o il Crudele ("o Cruel"), o, ulteriormente il Vendicativo ("o Vingativo") (Pero in aragonese, Petri in basco, Pedro in spagnolo, in portoghese e in galiziano, Pere, in catalano, Pedru in asturiano, Pèire in occitano e Pierre in francese; Coimbra, 18 aprile 1320 – Estremoz, 18 gennaio 1367), fu l'ottavo re del Portogallo e dell'Algarve dal 1357 al 1367.
