Capitulare de villis The Capitulare de villis is a text composed in c. 771–800 that guided the governance of the royal estates during the later years of the reign of Charlemagne (c. 768–814). It lists, in no particular order, a series of rules and regulations on how to manage the lands, animals, justice, and overall administration of the king's property and assets. The document was meant to lay out the instructions and criteria for managing Charlemagne's estates and was thus, an important part of his reform of Carolingian government and administration.
