The honour of Mowbray, which was created by King Henry I for Nigel d'Aubigny, was one of the greatest feudal estates of the Anglo-Norman kingdom, with territories in ten English counties and in Normandy. The 400 collected charters of the first three generations of the Mowbray family provide abundant material for a study of the feudal structure, economy, and administration of the honour between 1107 and 1191. The introduction to the collection examines such topics as the pattern of enfeoffment and ecclesiastical endowment, the management of the demesne, the process of colonization, and the organization of the household.
