A recent discovery in the British Library sheds light on the survivors of the Black Death, one of history's deadliest pandemics, which occurred between 1346 and 1353. The document, found in the records of the Ramsey Abbey manor in Warboys, Huntingdonshire, England, lists 22 tenants who fell ill during the plague and their recovery times. The average absence from work was between three and four weeks, with some recovering as quickly as one week while others took up to nine weeks. This finding suggests that wealthier individuals, who occupied larger holdings, may have had better recovery rates due to higher living standards, potentially allowing them to avoid secondary infections. This challenges previous assumptions that the plague indiscriminately affected all social classes. The research also highlights the significant societal impact of the pandemic, as the number of sick tenants represented a tenfold increase in typical summer illnesses. The findings underscore the resilience of medieval peasants, many of whom returned to work despite severe symptoms. This research was conducted as part of a Leverhulme Trust project, aiming to model the social connectivity during the Black Death.
