The medieval knight has a distinctive silhouette, despite the numerous legends which blur historical reality. At the turning point between the 12th and 13th centuries, while the feudal order was slowly disappearing in favor of the overwhelming royal will, some men stood apart from their contemporaries by their ability to fight on horses. They held the power and were considered little by little as the ruling class; they were the lords of the land. Thibaut des Puys de Morsaing, a young and poor bachelor, is about to achieve great success and become a rich land owner. Following his father’s steps, who died during the Crusades, and his godfather’s, Tristan de Maumesnil, he grasps the opportunities offered to him. The many events in the life of this imaginary character are used as a pretext to stage France’s medieval society, from king Philippe Auguste to Saint Louis.
