Seneschal of Périgord explained

The Seneschal of Périgord was an officer carrying out and managing the domestic affairs of the lord of the County of Périgord. During the course of the twelfth century, the seneschalship also became an office of military command.

The seneschal managed the household, coordinating between the receivers of various landholdings and the chamber, treasury, and the chancellory or chapel. The seneschals of Gascony, like those appointed in Normandy, Poitou, and Anjou, had custody of demesne fortresses, the regional treasuries, and presidency of the highest court of regional custom.
