What were Charlemagne's traveling royal inspectors called?

Charlemagne’s traveling royal inspectors were called missi dominici, Latin for “envoys of the lord” or “envoys of the ruler.” They represented the king in distant parts of the Carolingian realm and helped extend central authority across a large empire.

The missi investigated local administration, heard complaints, supervised counts and church officials, enforced royal orders, and sometimes distributed capitularies. Their work addressed a practical problem: Charlemagne could not personally visit every region or monitor every local official.

They were commonly sent in pairs, usually one lay official and one churchman, to reduce local bias and combine legal, political, and ecclesiastical expertise. A major reform in 802 made the system more regular. Counts administered local territories, but missi dominici inspected those counts on the king’s behalf; they were not simply another name for counts or palace officers.
