The period between the accession of David I and the death of Alexander III was marked by dependency upon and relatively good relations with the Kings of England. The period can be regarded as one of great historical transformation, part of a more general phenomenon, which has been called "Europeanisation". The period also witnessed the successful imposition of royal authority across most of the modern country. After David I, and especially in the reign of William I, Scotland's Kings became ambivalent about the culture of most of their subjects. As Walter of Coventry tells us, "The modern kings of Scotland count themselves as Frenchmen, in race, manners, language and culture; they keep only Frenchmen in their household and following, and have reduced the Gaels to utter servitude."
