Blanche of Bourbon, born in the year 1339, was an esteemed aristocrat who held the title of Queen of Castile through her marriage to King Peter of Castile in 1353. Her union with Peter, however, was marred by his infidelity, as he ultimately abandoned her for his mistress, Maria.
Following her husband's betrayal, Blanche faced a life of confinement. She spent her remaining years imprisoned in various locations, including Arévalo, the Alcázar of Toledo, and finally Medina Sidonia. These years were marked by isolation and hardship, a stark contrast to her royal status.
Blanche's life came to an end in 1361, although the circumstances surrounding her death remain a subject of debate. Her story reflects the tumultuous nature of royal life in the fourteenth century, characterized by political intrigue and personal tragedy.
