The system by which medieval nuns and monks administered their monastic households has long been known to historians. Headed by a prioress, prior, abbess, or abbot, a group of officers executed the daily running of a monastery’s internal affairs by what is called the obedientiary system. But our evidence about the heads of the houses, their monastic officers, and their incumbent duties comes almost exclusively from the numerous accounts and studies of male houses. Knowledge about the officers and administration of female convents has been inferred largely from what we know about the male monasteries, and from a lone description of the officers and their duties found among the records of the convent of Barking Abbey.
