Meantime, the Baiovarii or Bavarians had conquered the upper part of Rhætia, and in the beginning of the seventh century their Duke, Garibaldi II., succeeded in checking the frequent inroads of the Slavs, although he did not succeed in entirely excluding them from the country; in the eastern portion of which they remained for a considerable period. Towards the end of the eighth century (about 789) the whole of what is now known as Tyrol came under the sovereignty of Charlemagne, who crushed the Lombards, and a few years later succeeded in also subduing the Baiovarii. During the centuries of internecine warfare, with its concomitants of rapine and chaos, which succeeded the evacuation of Rhætia by the Roman forces, most of the original inhabitants or peaceably disposed Romanized Rhætians fled with other fugitives from the southern or northern plains to the valleys and byways amid the mountains which hitherto probably had been almost if not entirely unpopulated. Here they settled, leaving the main routes open to the passage of the Teutonic invaders bent on the plunder of the Italian cities and plains, who, we may imagine, did not greatly trouble themselves regarding the byways or waste time in conquering those who had thus hidden themselves amid the higher Alpine valleys and fastnesses. The result of this is seen in the circumstance that whilst in many cases the out-of-the-way places and villages to this day preserve their original Romanized Rhætian names, those upon the main routes of travel have in many instances a purely Teutonic nomenclature. [Sidenote: "THE LAND IN THE MOUNTAINS"] The great Empire which Charlemagne created had strangely enough no natural delimitations, and when it was divided, in A.D. 806, into three portions amongst his sons, the division was not made upon any usually recognized system or plan. Tyrol still was unknown by that name, the country about that time being known as "Das Land im Gebirge," or "The Land in the Mountains." The immediate successors to the divided empire of Charlemagne were far less able than he to cope with the anarchy which so frequently overwhelmed south-eastern and north-eastern Europe in those days. There was practically no such unity as now prevails, and, owing to this, the powerful nobles and ecclesiastics gradually succeeded in dividing up the land amongst themselves according to the almost universal custom of the Middle Ages.
