The so-called House of Dunkeld is a historiographical and genealogical construct to illustrate the clear succession of Scottish kings from 1034 to 1040 and from 1058 to 1290.
It is dynastically sort of a continuation to Cenél nGabráin, "race of Fergus", as "house" an originally Celtic concept to express one of the two rivalling leader clans of early medieval Scotland, whose founding father is king Fergus Mor of Dalriada. This Ferguside royal clan had rivalled the crown (of Dalriada, then that of Alba) against the Cenél Loairn, the later House of Moray for the preceding four or more centuries. The Cenél nGabráin were represented by the so-called House of Alpin before Dunkeld.
Genealogically Dunkeld dynasty is based on Duncan I of Scotland being of a different agnatic clan than his predecessor and maternal grandfather Malcolm II of Scotland. However, sociohistorically seen a more essential point to start has been regarded to been the reign of Duncan I's son Malcolm III of Scotland which happens to coincide with the start of the centuries-long period of strong influence from the southern neighbor, the Kingdom of England.
During the time of the so-called House of Dunkeld, succession to the Scottish throne evolved towards primogeniture instead of the Irish-Celtic tradition of tanistry and the Pictish traditions, were they matrilineal or not. Although the contemporaries did not have a common name for these monarchs, they were a family who formed a hereditary kingship.
Distinctive characteristics of the developments of society during this dynasty:
The so-called Dunkeld dynasty rose to rule in a time when the kingdom was fragmentary, under increasing outside threats, and some monarchs started to initiate more centralized government.
The dynasty ended at a time when immigrant-originated feudal families had reached material level almost as high as the kings and the benefitters of feudal system desired to better guarantee their positions, rights and properties. Even at cost of national independence.
Following the end of the Dunkelds, Scotland fell in the First Scottish War of Independence against England.
On Alexander III's death his granddaughter Margaret was recognised as "right heir", as had been agreed in Alexander's lifetime, but she was never inaugurated as Queen of Scots.
