Resumen:
The objective of this paper is to analyze the Monastic Reform of Ferdinand II of Aragon, during his first Castilian regency (1504-1507), after the death of his wife Elizabeth. It examines a period that is less known in history, which we intend to enlighten with documents sometimes published and sometimes too unedited, putting in relation the reforming processes advanced from the court with the situation of the religious orders, the dealings with Rome and the succession crisis that Philip of Habsburg faced with the Catholic king. In that context we will notice to what extent the Aragonese monarch was involved in the monastic renewal, giving it continuity and new nuances at the beginning of the 16th century.
