Alpin, the last of the Scoto-Irish kings, and the son of Eocha IV. and of Urgusia, now mounted the throne. He was killed in 836, near the site of Laicht castle, on the ridge which separates Kyle from Galloway. The fiction that Alpin fell in a battle with the Picts, when asserting his right to the Pictish throne, has long been exploded. In 836 Kenneth, the son of Alpin, succeeded his father. He was a prince of a warlike disposition, and of great vigour of mind and body. He avenged the death of his father by frequent inroads among the people dwelling to the south of the Clyde; but the great glory of his reign consists in his achievements against the Picts, which secured for him and his posterity the Pictish sceptre. The Pictish power had, previous to the period of Kenneth’s accession, been greatly enfeebled by the inroads of the Danish Vikingr; but it was not till after the death of Uven, the Pictish king, in 839, after a distracted reign of three years, that Kenneth made any serious attempt to seize the Pictish diadem. On the accession of Wred, Kenneth, in accordance with the principle of succession said by Bede to have prevailed among the Picts, claimed the Pictish throne in right of Urgusia, his grandmother; Wred died in 842, and after an arduous struggle, Kenneth wrested the sceptre from Bred, his successor, in 843, after he had reigned over the Scots seven years. Burton[102] thinks there can be no doubt that the two countries were prepared for a fusion whenever a proper opportunity offered, but that this was on account of a matrimonial alliance between the two royal houses cannot with certainty be ascertained.[103] As we have said already, it is extremely improbable that Kenneth gained his supremacy by extermination. The Picts certainly appear to have suffered severe defeat, but the likelihood is that after Kenneth succeeded to the throne, a gradual fusion of the two people took place, so that in course of time they became essentially one, speaking one language, obeying the same laws, and following the same manners and customs. If we knew for certain to what race the Picts belonged, and what language they spoke, it might help us not a little to understand the nature and extent of the amalgamation; but as we know so little about these, and as the chroniclers, in speaking of this event, are so enigmatical and meagre, we are left almost entirely to conjecture. We are certain, at any rate, that from some cause or other, the kings of the Dalriadic Scots, about the middle of the 9th century, obtained supremacy over at least the Southern Picts, who from that time forward ceased to be a separate nation.[104]
