Hedwig Jagiellon (1408–1431)

Hedwig Jagiellon was a Polish and Lithuanian princess, and a member of the Jagiellon dynasty. For most of her life she, as the only child of Władysław II Jagiełło, was considered to be heiress of the Polish and Lithuanian thrones. After the birth of Jagiello's sons in 1424 and 1427, Hedwig had some support for her claims to the throne. She died in 1431 amidst rumors that she was poisoned by her stepmother Sophia of Halshany.
