By Alan V. Murray
PhD Dissertation, University of St Andrews, 1988
Abstract: The starting-point of this thesis is the question of the origin of the nobility in the Latin Kingdom of Jerusalem up to 1131. This is discussed in parallel with the question of the origins of the monarchy itself and that of relations between the two institutions."
For about 300 years following the Norman Conquest in 1066, the Norman kings and their high nobility spoke only one of the langues d'oïl called Anglo-Norman, which was a variety of Old Norman used in England and to some extent elsewhere in the British Isles during the Anglo-Norman period and originating from a northern dialect of Old French, whilst English continued to be the language of the common people. Middle English was influenced by both Anglo-Norman and, later, Anglo-French (see Anglo-Norman language, "Characteristics").
