As noted before, the expansion of Dalriada was accomplished not so much by invasion, as by the joining together in marriage of the Dalriadans and the Picts. The two kingdoms of Picts and Dalriada/Scotti would practically fall into place by the year 844 AD. In that year Cinaeth, or Kenneth, MacAlpin unified the two into the single Kingdom of the Scots.
According to Norman Davies in his book, The Isles ~ A History: “By the early ninth century, the relationship of Dalriada to Pictland was characterized by an odd combination of political subservience and culteral ascendancy.” (
Kenneth MacAlpin brought the Stone of Destiny from Eire and had it installed in the church at Scone (hence its one alternate name) for his own inauguration. The act was perhaps somewhat of a conciliatory gesture on the part of Kenneth toward his own mother’s Pict ancestors; Scone was the seat of the Pictish kings. From that point to the present time, the kingdom forged by Kenneth would be known neither by the name of Pict nor Dalriada, but rather as Scotia, or Scotland. Upon the Stone of Destiny the High Kings of Eire had been, and later, Scotland would be crowned.
