Biography
Born in 1545, Don Carlos was the long-awaited male heir to the vast empire of Philip II of Spain. His life, however, was shadowed from the start; his mother died just days after his birth. As he grew, reports described a young man of erratic temperament and physical ailments, his behavior growing increasingly volatile. The breaking point came in early 1568, when his father, the king, ordered his arrest. Carlos spent his final six months in solitary confinement in a castle room, dying under mysterious circumstances at just twenty-three. His story transcended history, morphing into potent propaganda for Spain's enemies and later inspiring major works by Schiller and Verdi, cementing his legacy as the doomed prince.
