Missus dominicus, an "envoy of the lord" in Frankish court culture.
The missi were the last attempt to preserve centralised control in the Holy Roman Empire.
In a court run by a bishop and a representative of the emperor, and in the presence of Gregory, Ingoald, the Abbot of Farfa, claimed that the Frankish emperors had granted them the lands, and that Popes Adrian I and Leo III had taken possession of the land illegally.
