Scotland had now reached her permanent and lasting frontier towards the south, the dependent principality of Strath Clyde having apparently, during the course of this reign, been finally incorporated with the greater kingdom. When Donald, son of the Eogan who shared in the bloody fight of Brunanburgh, died on a pilgrimage in 975, he seems to have been succeeded by his son Malcolm, whose death is noticed by the Irish Tighernach under the date of 997.[122] The last king of Strath Clyde who has found a place in history is Eogan “the bald,” who fought by the side of the Scottish king at Carham,[123] probably a son of the British Malcolm whose family name he bears; and in the person of this Eogan the line of Aodh’s son Donald appears to have become extinct. The earliest authorities of the twelfth century give the title of “king of the Cumbrians,” meaning undoubtedly the northern Cumbria or Strath Clyde, to Malcolm’s grandson Duncan, and it is probable that upon the failure of the line of Scoto-British princes, the king of Scotland placed his grandson over the province, which from that time, losing the last semblance of independence, ceased to be ruled by a separate line of princes.[124] To Malcolm the Second has sometimes been attributed the foundation of an Episcopal See at Mortlach, which was afterwards transferred to Aberdeen;[125] and though as far as relates to the establishment of a regular diocese this account must be rejected, Malcolm, in imitation of his father’s policy in the case of Brechin, may have “given Mortlach to the Lord;” or, in other words, he may have founded and endowed a Culdee monastery on this spot. As the erection of a religious establishment in those days necessarily implies the possession of the surrounding district, if the tradition is correct which connects Mortlach with the reign of Malcolm the Second, the plains of Lothian were not his only conquest; and, in the same manner as Kenneth acquired Angus, he must have annexed to the dominions of the Scottish crown some portion of the ancient kingdom which once aspired to be the leading principality amongst the Pictish provinces of the north.[126]
