A more thorough explanation:

Definition: A vidame was an officer in French feudal law who represented the bishop. They were responsible for managing the bishop's lands and protecting their rights. Over time, some vidames became feudal nobles by turning their offices into fiefs. They continued to take their titles from the seat of the bishop they represented, even if their lands were located elsewhere.

One example of a vidame is the vidame of Chartres. This officer represented the bishop of Chartres and was responsible for managing the bishop's lands in the area. Another example is the vidame of Rheims, who represented the bishop of Rheims.

These examples illustrate how vidames were important officials in the feudal system of France. They acted as representatives of the bishop and were responsible for managing their lands. Some vidames even became feudal nobles by turning their offices into fiefs.
