The timeline overlaps with the Peace of God movement and the Gregorian reforms which legal historian Harold Berman calls the Papal Revolution in his book Law and Revolution: The Formation of the Western Legal Tradition. Also coincides with the beginnings of renavatio that Charles Taylor mentions in A Secular Age. You could argue though that perhaps it took some time until the population fully Christianized; it is precisely in this time period we start seeing the use of familiar Biblical along with a set of standardized Germanic first names all across Europe while old Germanic naming conventions start to disappear.
