 The alterations in the domestic administration of the papal household, necessitated under Clement V and John XXII by the transition from the "natural economy" to the "economy of money", were of a far-reaching nature; but it was only after the return of Martin V from Avignon to Rome in 1418 that the modern offices were gradually evolved, to attain subsequently during the Renaissance a full development.In the sixteenth century a "maestro DI casa" 'master of the house(hold)' stood at the head of the whole administration of the papal household.Towards the end of the 16th century, the same official was accorded the title of "prefetto del Sacro Palazzo Apostolico", and under Urban VIII (1623–44) he was first granted the title of "Maggiordomo Pontificio" 'pontifical majordomo'.
