It was with the wealthy nobles and landowners that Charlemagne fought some of his hardest battles, though no sword was drawn or open war declared. Not only were most of the high offices at court in their hands, but it was from their ranks that the counts, and later the viscounts, were chosen who ruled over the districts into which the Empire was divided and subdivided. The count received a third of the gifts and rents from his province that would have otherwise been paid to the King; and these, if he were unscrupulous, he could increase at the expense of those he governed. He presided in the local law-courts and was responsible for the administration of justice, the exaction of fines, and for the building of roads and bridges. He was in fact a petty king, and would often tyrannize over the people and neglect the royal interests to forward his selfish ambitions. The Merovingians had tried to limit the authority of the counts and other provincial officials by occasionally sending private agents of their own to inquire into the state of the provinces and to reform the abuses that they found. Charlemagne adopted this practice as a regular system; and at the annual assemblies he appointed _Missi_, or ‘messengers’, who should make a tour of inspection in the district to which they had been sent at least four times in the year and afterwards report on their progress to the Emperor. Wherever they went the count or viscount must yield up his authority to them for the time being, allowing them to sit in his court and hear all the grievances and complaints that the men and women of the district cared to bring forward. If the _Missi_ insisted on certain reforms the count must carry them out and also make atonement for any charges proved against him. Here are some of the evils that the men of Istria, a province on the Eastern Adriatic, suffered at the hands of their lord, ‘Johannes’, and that the inquiries of the royal _Missi_ at length brought to light. Johannes had sold the people on his estates as serfs to his sons and daughters: he had forced them to build houses for his family and to go voyages on his business across the sea to Venice and Ravenna: he had seized the common land and used it as his own, bringing in Slavs from across the border to till it for his private use: he had robbed his tenants of their horses and their money on the plea of the Emperor’s service and had given them nothing in exchange. ‘If the Emperor will help us,’ they cried, ‘we may be saved, but if not we had better die than live.’ From this account we can see that Charlemagne appeared to the mass of his subjects as their champion against the tyranny of the nobles, and in this sense his government may be called popular; but the old ‘popular’ assemblies of the Franks at which the laws were made had ceased by this reign to be anything but aristocratic gatherings summoned to approve of the measures laid before them.
