The Davidian Revolution is a name given by many scholars to the changes which took place in the Kingdom of Scotland during the reign of David I (1124–1153). These included his foundation of burghs, implementation of the ideals of Gregorian Reform, foundation of monasteries, Normanisation of the Scottish government, and the introduction of feudalism through immigrant Norman and Anglo-Norman knights. Overview King David I is still widely regarded as one of the most significant rulers in Scotland's history. The reason is what Barrow and Lynch both call the "Davidian Revolution". David's "revolution" is held to underpin the development of later medieval Scotland, whereby the changes that he inaugurated grew into most of the central non-native institutions of the later medieval kingdom. Barrow summarises the many and varied goals of David I, all of which began and ended with his determination "to surround his fortified royal residence and its mercantile and ecclesiastical satellites with a ring of close friends and supporters, bound to him and his heirs by feudal obligation and capable of rendering him military service of the most up-to-date kind and filling administrative offices at the highest level". European Revolution: the wider context Since Robert Bartlett's The Making of Europe: Conquest, Colonization and Cultural Change, 950–1350 (1993), reinforced by Moore's The First European Revolution, c.970–1215 (2000), it has become increasingly apparent that better understanding of David's "revolution" can be achieved by placing it in the context of a wider European "revolution". The central idea is that from the late 10th century onwards the culture and institutions of the old Carolingian heartlands in northern France and western Germany spread to outlying areas, creating a more recognisable "Europe". In this model, the old Carolingian Empire formed a "core" and the outlying areas a "periphery". The Norman conquest of England in the years after 1066 is considered to have made England more like if not part of this "core". In applying this model to Scotland, it would be considered that, as recently as the reign of David's father Máel Coluim III, "peripheral" Scotland had lacked – in relation to the "core" cultural regions of northern France, western Germany and England – respectable Catholic religion, a truly centralised royal government, conventional written documents of any sort, native coins, a single merchant town, as well as the essential castle-building cavalry elite. After David's reign, it had gained all of these. During the reign of
