De ordine palatii

De ordine palatii (On the governance of the palace) is a treatise written by Hincmar, archbishop of Rheims, in 882 for Carloman II on the occasion of his accession to the throne of West Francia.

It claims to be based on a treatise of the same name by Adalhard, who was an adviser to Emperor Charlemagne and abbot of the monastery of Corbie, although this document has not survived.

In the treatise, Hincmar outlined the duties of a king and a system for the organisation of his palace, in an apparent attempt to restore Carolingian government to the form it had under Louis the Pious.
