The controversy which concerns us now, as it once concerned the thirteenth-century participants, centres upon the king’s right to demand corrodies in monastic establishments for his own nominees. Thus it is necessary to begin by defining the term ‘corrody’ in the present context. In describing a corrody as ‘nothing more than an allowance consisting of a share in a common fund’, Professor Hamilton Thompson neatly encapsulated the multifarious forms which it could take; he also drew attention to its potentially disastrous effects when he noted that at least one person, who should have known better, believed that corrodies were so called because they were corrosive. The allowances or provisions were specified in a written agreement between the monastic chapter and the prospective recipient and might include board, lodging, items of clothing, and cash payments, or any one of these, or a combination of them; and so they were often entered on monastic officials’ expense accounts as annuities, pensions, or liveries (liherationes). Acting on their own initiative and often against episcopal injunctions, religious houses in financial straits made such grants to laymen, whose wives were sometimes included, in return for a lump sum or a donation of property. The corrodian who paid cash or bequeathed part of his estate provided an immediate and welcome boost in income for the community which received him, and he and his family gained security and comfort in their declining years. But the financial relief for the monastery which had guaranteed hospitality for life could, and did, turn into a liability when the beneficiaries lived longer than had been anticipated. In addition, outsiders, by virtue of their rights as founders and benefactors, made certain claims on religious houses, among which was the requisition of corrodies on behalf of relatives or retainers. It was this form of exploitation in which the King himself was the chief offender, and Henry III, in financial straits, would argue that he was in principle the patron of all religious establishments in the country.
