ABSTRACT
There are many sources concerning the Spanish Hospitallers during the reign of the Catholic Kings and, what is more, most of them concern the monarchy.1 This is not particularly surprising: from what we know about what occurred in other European kingdoms at the end of the fifteenth century and the beginning of the sixteenth, the situation was not very different. In each and every one of them, the Order of St John was tightly controlled by the monarchy,2 so it is not surprising that in Spain the relations between the Order and the monarchy were most significant during this period.
