Like her sister before her, Jadwiga’s death was connected to childbirth. Childless for over a decade after her marriage to Jagiełło, she finally gave birth to a much-awaited child on 22 June 1399. She was called Elżbieta Bonifacja, honouring an arrangement Jadwiga had made with Pope Boniface. He agreed to be the child’s godfather on the condition that Jadwiga named her after him. But mother and daughter only managed three weeks together. First Elżbieta died, followed four days later by her mother, who was just 26 years old. The two were buried together in Wawel Cathedral.
