On reviewing the whole course of the Teutonic conquest of our island we cannot fail to be struck by the different rates of speed at which that conquest proceeded at different times. By about the middle of the sixth century the invaders seem to have possessed themselves of nearly all the country lying to the east of a line drawn from Berwick-on-Tweed through Lichfield to Salisbury. After that period, however, their advance, never very rapid, becomes extremely slow. Wales the Saxons never conquered. “West Wales,” as Devon and Cornwall were called, were not subdued till the ninth century. Cumberland, which formed part of the Celtic kingdom of Strathclyde, does not seem to have become English till the close of the seventh century, and even then was very loosely joined to the Anglian kingdom of Northumbria. It is to be hoped that we may one day obtain some clearer light on the reason for this great difference in the rate of conquest between the eastern and western halves of the island; how far it may have been due to the different resisting powers of two Celtic races, the “Brythonic” and “Goidelic”; whether earlier Saxon settlements along the shore of the German Ocean facilitated the work of the new invaders; or whether the flat alluvial lands of the east, more easily overrun by mounted bands of freebooters than the rough mountainous country of the west, were the chief factors in the problem. A question which has been often and fiercely discussed and on which probably the last word has not yet been said is: “How far did the great movements of invasion which we have been discussing amount to an actual replacement of one population by another?” or, in other words: “Are the Englishmen of to-day pure Saxons and Angles or partly Celts?” In considering this question two factors have to be considered: (1) the amount of new population imported into the country; and (2) the degree to which the invaders carried the process of extermination of the older inhabitants. As to the first point we are furnished with extremely scanty information by all our authorities. The mythical “three keels” and “five keels,” which the chroniclers speak of as containing the whole forces of the invaders, point only to a scanty number of warriors, accompanied probably by their horses, but certainly not by their wives and children. The story of the legendary Rowena, on the other hand, suggests--what is doubtless the truth--that the invaders, once established in the land, sent speedily for the wives and daughters whom they had left by the Elbe or the Baltic. One late authority speaks of the Saxons as inviting over so many of their kith and kin that an island which they had previously inhabited was left almost void of people. Undoubtedly every indication of language and of later social state points to the conclusion that the invasions were not mere raids of freebooting warriors, but great national migrations such as were
