those who had a great-grandfather who had been king. Kingly fathers were not frequently succeeded by their sons, not because the Picts practised matrilineal succession, but because they were usually followed by their own brothers or cousins (agnatic seniority), more likely to be experienced men with the authority and the support necessary to be king. This was similar to tanistry. 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. The later Mormaers are thought to have originated in Pictish times, and to have been copied from, or inspired by, Northumbrian usages. 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. Society The archaeological record provides evidence of the material culture of the Picts. It tells of a society not readily distinguishable from its British, Gaelic, or Anglo-Saxon neighbours. Although analogy and knowledge of other so-called 'Celtic' societies (a term they never used for themselves) may be a useful guide, these extended across a very large area. Relying on knowledge of pre-Roman Gaul, or 13th-century Ireland, as a guide to the Picts of the 6th century may be misleading if the analogy is pursued too far. As with most peoples in the north of Europe in Late Antiquity, the Picts were farmers living in small communities. Cattle and horses were an obvious sign of wealth and prestige, sheep and pigs were kept in large numbers, and place names suggest that transhumance was common. Animals were small by later standards, although horses from Britain were imported into Ireland as breed-stock to enlarge native horses. From Irish sources, it appears that the elite engaged
