What duties did the royal baillis perform under Philip II Augustus?

Under Philip II Augustus, the royal baillis (bailiffs) were established as a new class of administrative officers to strengthen royal control over the kingdom and the royal domain. Appointed directly by the king, they served as reliable representatives of the crown, tasked with supervising the local prévôts (provosts) who had previously managed royal revenues.12

The primary duties performed by the baillis included:

• Administration and Supervision: They oversaw the conduct of local provosts and managed various aspects of the royal domain.2
• Justice: They held court and administered justice in the king's name.2
• Finance: They were responsible for collecting royal revenues and extraordinary taxes from the domain.12
• Military: They were authorized to call up and lead armed forces for the king.12

Initially, these officers did not have fixed territorial districts and functioned similarly to circuit commissioners, moving to hold periodic local sessions. By appointing these officials—often natives of the Île-de-France—Philip Augustus successfully improved the efficiency of his lordship and centralized his administration.1
