The only child of the Holy Roman Emperor, whose brief reign as Queen of Hungary became a desperate struggle to secure her son's stolen inheritance.
Elizabeth of Luxembourg was born to rule, but lived a life defined by its frantic, tragic defense of that right. As the sole offspring of Emperor Sigismund, she was the heiress to his vast realms—Hungary, Bohemia, and the Holy Roman Empire itself. Her marriage to the Habsburg Archduke Albert V of Austria was a dynastic masterstroke, uniting two powerful houses. When Sigismund died in 1437, Albert and Elizabeth were crowned, but his reign lasted a mere two years. His sudden death in 1439 left Elizabeth a pregnant widow, fighting to protect the throne for her unborn child. She gave birth to a son, Ladislaus, and had him crowned King of Hungary while still an infant. But the Hungarian nobility, wary of a long regency, elected the Polish king Władysław III instead. What followed was a civil war, with Elizabeth a central, embattled figure. She died suddenly in 1442, likely from complications following a surgery, her mission unfulfilled. Her infant son, known posthumously as Ladislaus the Posthumous, would inherit claims but never wield real power, his fate underscoring the perilous position of a female heir in a world governed by swords and male succession.
