was the head--“Andegavis,” Angers.[234] [233] From the point where the Sarthe joins it, this river is now called the Maine. In the middle ages it had but one name, _Meduana_, from its source to its junction with the Loire. The old nomenclature is far more convenient for historical purposes. [234] The ecclesiastical history of Angers is in _Gallia Christiana_, vol. xiv. col. 543 _et seq._ City and county acquired a new importance through the political arrangements by which the Karolingian realms were divided between the three sons of the Emperor Louis the Gentle. By a treaty made at Verdun in 843, the original Frankish kingdom and its Saxon dependencies, answering roughly to what we call Germany now-a-days, fell to the second brother Louis; the Gallic conquests of the Franks, between the Moselle, the Rhone, the Pyrenees and the ocean, were the share of the youngest, Charles the Bald; while the necessity that the eldest brother Lothar, as Emperor, should hold the two capitals, Rome and Aachen, involved the creation in his favour of a middle kingdom consisting of a long narrow string of countries reaching from the Frisian to the Pontine marshes. Although the limits thus fixed were afterwards altered more than once, the main lines of this treaty left indelible traces, and from that day we may date the beginning of modern France and modern Germany. The tripartite division, however, was soon overthrown by the extinction of the elder or Lotharingian line; the incongruous middle kingdom fell asunder and became a bone of furious contention between its two neighbours, and the imperial crown itself was soon an object of rivalry no less fierce. On the other hand, the extent of territory actually subject to Charles the Bald fell far short of the limits assigned to him by the treaty. Even Charles the Great had scarcely been able to maintain more than a nominal sway over the vast region which stretched from the southern shores of the Loire to the Pyrenees and the Mediterranean Sea, and was known by the general name of Aquitania; its princes and its people, wrapped in the traditions of Roman culture and Roman greatness, held disdainfully aloof from the barbarian conquerors of the north, and remained utterly indifferent to claims of supremacy which each succeeding Karolingian found it more and more hopeless to enforce. To the west, again, in the peninsula of Britanny or Armorica, the ancient Celtic race preserved, as in the Welsh hills of our own island, its native tongue, its primitive laws and customs, and its separate political organization under a dynasty of native princes who owed, indeed, a nominal allegiance to the West-Frankish overlord at Laon, but whose subjection to him was scarcely more real than that of the princes of Aquitania, while their disaffection was far more active and far more threatening; for the pirate fleets of the northmen were
