Otto de Grandson, sometimes numbered Otto I to distinguish him from later members of his family with the same name, was the most prominent of the Savoyard knights in the service of King Edward I of England, to whom he was the closest personal friend and many of whose interests he shared. His misrule of the Channel Islands, particularly after he left England following Edward's death, prompted greater care of the English kings when considering provision of future life estates.

Savoyard knights in the service of Edward I
Edward I of England was associated with a faction of nobles and knights who came from the County of Savoy, and were favoured in England. Savoy became linked to the Plantaganet monarchy of England with the marriage of Edward I's parents Henry III of England and Eleanor of Provence in 1236. Eleanor of Provence was the daughter of Beatrice of Savoy.
