Inés de Castro was a noblewoman born in 1320 in Galicia, Spain. She became the secret wife of Peter I of Portugal, the heir to the Portuguese throne. Their relationship was controversial, as Peter's father, Afonso IV, disapproved of Inés due to her noble lineage and the political implications of their union. After Inés was murdered in 1355 on the orders of Afonso IV, Peter became king and sought to avenge her death. He famously had her exhumed and crowned posthumously as queen, declaring their love eternal. Inés de Castro's story is often seen as a tragic tale of love and political intrigue in Portuguese history.
