instituted in the twelfth century, the whole of Dalriada had long been incorporated amongst the districts acknowledging the jurisdiction of Constantine’s monastery of Dunkeld. The Anglian line of bishops also disappear during the same reign from the diocese of Whithern, and a population of Gaelic origin, distinguished from the earlier masters of the soil, whether of Cumbrian or Northumbrian race, is subsequently discovered in possession of the entire district.[22] The power of Northumbria was on the wane, her people, distracted by civil contests, were fast relinquishing the hold they had once acquired upon the districts to the westward of the Lothians; and as the Angles, weakened by internal discord, no longer opposed a formidable barrier to the Northern tribes, the latter, gradually increasing in power, seem to have been fast settling into a stronger and more compact kingdom, in which may be traced the nucleus of modern Scotland. The erection of Dunkeld, the sole deed of Constantine that has descended to posterity, may be traced to the inroads of the Northern _Vikings_, who, four years after his accession, made their first recorded appearance upon the British coasts, ravaging in the same year Lindisfarne and Iona. A few of the Scottish monks who escaped with life bore with them the relics of their founder, distributing their sacred charge between the new foundation of the Pictish sovereign and another monastery raised at Kells in Ireland; whilst the pre-eminence throughout North Briton, which had passed to Abernethy from Iona, appears to have been again transferred from the former monastery, and vested in Dunkeld, which was destined in its turn, before the close of the century, to be eclipsed and supplanted by St. Andrews.[23] [Sidenote: A. D. 839.] The male line of the family of Fergus appears to have terminated in the sons of the younger Angus, Eoganan and Bran, who were both killed in a disastrous battle with the Northmen; and for three years the two sons of Bargoit, Feredach and Bruidi, reigned over the Picts, the death of Bruidi making way for the first prince of the line of Dalriada, [Sidenote: A. D. 843.] Kenneth MacAlpin, who seems to have ascended the throne in right of the maternal ancestry of his father. For the next two centuries the united people of the Picts and Scots acknowledged the dominion of the MacAlpin dynasty; and though Kenneth and his immediate successors were still recorded in the annals of the age under the original title of “Kings of the Picts,” from the opening of the tenth century the ancient name of _Pict_, gradually dying out, was superseded by the more familiar appellation of _Scot_, extending, in course of time, to every tribe and every race from the Tweed and the Solway to the Pentland Firth, whose chieftains and leaders, whether native noble, or feudal baron, owned the authority and followed the banner of the representatives of the princes of Kintyre.[24] CHAPTER II.
