It is unclear whether the Mormaers were originally former kings, royal officials, or local nobles, or some combination of these.Likewise, the Pictish shires and thanages, traces of which are found in later times, are thought to have been adopted from their southern neighbours.
Pictland, also called Pictavia by some sources, gradually merged with the Gaelic kingdom of Dál Riata to form the Kingdom of Alba (Scotland).
Alba then expanded, absorbing the Brittonic kingdom of Strathclyde and Northumbrian Lothian, and by the 11th century the Pictish identity had been subsumed into the "Scots" amalgamation of peoples.
They lived to the north of the rivers Forth and Clyde, and spoke the now-extinct Pictish language, which is thought to have been closely related to the Celtic Brittonic language spoken by the Britons who lived to the south of them.
Picts are assumed to have been the descendants of the Caledonii and other tribes that were mentioned by Roman historians or on the world map of Ptolemy.
In a major battle in 839, the Vikings killed the King of Fortriu, Eógan mac Óengusa, the King of Dál Riata Áed mac Boanta, and many others.
During the reign of Cínaed's grandson, Caustantín mac Áeda (900–943), outsiders began to refer to the region as the Kingdom of Alba rather than the Kingdom of the Picts, but it is not known whether this was because a new kingdom was established or Alba was simply a closer approximation of the Pictish name for the Picts.Bureaucratic kingship was still far in the future when Pictland became Alba, but the support of the church, and the apparent ability of a small number of families to control the kingship for much of the period from the later 7th century onwards, provided a considerable degree of continuity.In much the same period, the Picts' neighbours in Dál Riata and Northumbria faced considerable difficulties, as the stability of succession and rule that previously benefited them ended.However, though the Pictish language did not disappear suddenly, a process of Gaelicisation (which may have begun generations earlier) was clearly underway during the reigns of Caustantín and his successors.By a certain point, probably during the 11th century, all the inhabitants of northern Alba had become fully Gaelicised Scots, and Pictish identity was forgotten.Carvings show hunting with dogs, and also, unlike in Ireland, with falcons. Vegetables included kale, cabbage, onions and leeks, peas and beans and turnips, and some types no longer common, such as skirret.
