It had been common even before Charlemagne's time to grant to monasteries and churches, and even to individuals, an extraordinary privilege which exempted their lands from the presence or visits of government officials. No public officer with the power to hear cases, exact fines, obtain lodging or entertainment for the king and his followers when traveling about, or make requisitions of any kind, was to enter the lands or villages belonging to the monastery or person enjoying the _immunity_. These exemptions were evidently sought with a view to getting rid of the exactions of the king's officials and appropriating the various fines and fees, rather than with the purpose of usurping governmental prerogatives. But the result was that the monasteries or individuals who were thus freed from the requisitions of the government were left to perform its functions,--not, however, as yet in their own right, but as representatives of the king.[60] It is not hard to see how those who enjoyed this privilege might, as the central power weakened, become altogether independent. It is certain that a great many landowners who had been granted no exemption from the jurisdiction of the king's officers, and a great many of the officers themselves, especially the counts and margraves, gradually broke away altogether from the control of those above them and became the rulers of the regions in which they lived. [Sidenote: Tendency to hereditary offices.] The counts were in a particularly favorable position to usurp for their own benefit the powers which they were supposed to exercise for the king. Charlemagne had chosen his counts and margraves in most cases from the wealthy and distinguished families of his realms. As he had little money, he generally rewarded their services by grants of estates, which only served to increase their independence. They gradually came to look upon their office and their land as private property, and they were naturally disposed to hand it on to their sons after them. Charlemagne had been able to keep control of his agents by means of the _missi_. After his death his system fell into disuse and it became increasingly difficult to get rid of inefficient or rebellious officers.
