the Picts

The nature of kingship changed considerably during the centuries of Pictish history. While earlier kings had to be successful war leaders to maintain their authority, kingship became rather less personalised and more institutionalised during this time. 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.[37]

The later Mormaers are thought to have originated in Pictish times, and to have been copied from, or inspired by, Northumbrian usages.[38] 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.[39]
