Jeanne de Constantinople: Comtesse de Flandre et de Hainaut

A young noblewoman who inherits rich provinces endures orphanhood, political captivity at the French court, and a politically arranged marriage to an adventurous foreign prince whose later imprisonment triggers national crises. She confronts familial and ecclesiastical scandal when her sister marries a man under holy orders, faces a popular uprising fueled by an impostor claiming to be her presumed-dead father, and seeks royal aid to restore order. After the prince's return and death, she devotes herself to governance, charitable foundations, restraining feudal abuses, and pious retirement, leaving a legacy commemorated by contemporaries and religious communities.
