Britain after the departure of the legionaries appears to have suffered her full share of the calamities of that disastrous epoch, and the episodes of invasion and conquest enacted throughout the continental provinces of the expiring empire were repeated with similar results, within the narrower limits of her ancient island dependency. A continuous stream of Teutonic invaders poured without ceasing upon her shores, Jutes, Saxons, and Frisians peopling the south-eastern coasts, whilst further towards the north swarmed the Anglian tribes who were destined to fix an imperishable name upon the island. Towards the middle of the sixth century an additional impetus appears to have been given to the torrent of Anglian invasion by the arrival of Ida, the reputed founder of the Northumbrian kingdom, and leader of the Bernician Angles, whose descendants formed so important an element in the Teutonic population of southern Scotland. No record of his prowess is to be found in the annals of his countrymen; his name alone survives with that of his forgotten foe, “the dark lord”--Dutigern; but the precipitate flight of the British bishop from York, the sudden extinction of Christianity throughout the diocese, the name of _Gwrth Bryneich_--or Bernicia’s thraldom--by which the famous fortress of Bamborough was known amongst the conquered people, and the ominous title of “the Flame-Bearer,” applied to the mighty Angle in the lays of the hostile bards, sufficiently attest the ruthless energy with which he extended the dominion of his race from the marshy plains of Holderness to the distant islets of the Forth.[2] From the Humber to the Tyne the country was known amongst the Britons as _Deheubarth_, or “the southern part,” whilst beyond that river and the ruins of the southern wall, the district stretching to the Forth was distinguished as _Bryneich_, or “the country of the braes;” and it was within the boundaries of the latter province that the Anglian population of the Lothians first established themselves as conquerors in the land which their descendants still occupy.
