One of the chief amongst the many changes and reforms instituted by Charlemagne was the sub-division of the countries he had conquered and welded together to form his Empire into margravates or departments which he placed under the rule of his nobles and other officials whom he appointed for the purpose. Although this system undoubtedly worked well during his powerful sway, after his death and during the anarchy and dissension which distinguished the reigns of his immediate successors what might have been expected happened. The more powerful of the nobles and officials and their descendants soon commenced to regard their offices as of the nature of hereditary appointments, and in consequence with the development of this idea small dynasties were gradually founded, and towards the close of the tenth century three of these had sprung into existence in Tyrol. These three Countships or _Grafschaften_ were of Andechs, Eppan, and Tyrol, and the country was eventually divided up amongst them and the great ecclesiastical lords of the Sees of Trent, Brixen, and Coire. As is the case with so much of early Tyrol history and events, very scanty information of a reliable character has come down to us regarding the origin of these three great families of nobles who held sway in the country. Nor is it for the purpose of this book necessary to enquire closely into the evidence we have. The origin of the family of Andechs is almost entirely unknown, although for a considerable period they were the most powerful of the three families we have named. The Eppans are believed to have been descendants of a natural son of a Duke of Bavaria, and their long and bloody feud with the Bishops of Brixen on account of lands taken from them and given to the See is enshrined in Tyrol history and legend. The third family, the Counts of Tyrol, though originally by no means the most important, was destined to outlast the other two, and eventually to become possessed of most of the country and give its name to ancient Rhætia. Although even in the days of the Roman occupation there appears to have been a Castle Tyrol, which was the residence of a centurion, the family, as it is generally known, is supposed to have taken its origin from Count Hunfried who lived in the reign of Charlemagne, and was also Count of Vintschgau. This noble came into prominence on the division of Charlemagne's Empire amongst his three sons; but it appears to be probable that it was not until the middle part of the thirteenth century that one of the owners of Castle Tyrol or Teriolis first took the title of Counts of Tyrol.[5]
