The final plague outbreak in Scotland 1644-1649: Historical, archaeological, and genetic evidence.

This paper has several aims: to determine if Yersinia pestis was the causative agent in the last Scottish plague outbreak in the mid-17th century; map the geographic spread of the epidemic and isolate potential contributing factors to its spread and severity; and examine funerary behaviours in the context of a serious plague epidemic in early modern Scotland. Results confirm the presence of Y. pestis in individuals associated with a mid-17th century plague pit in Aberdeen. This is the first time this pathogen has been identified in an archaeological sample from Scotland. The geographic spread of the plague from 1644 through to 1649 is generally, with some key exceptions, restricted to the central lowlands of Scotland. The role of administrative responses to the epidemic in managing its spread and distribution is unclear. Finally, normative funerary practices tended to co-exist with mass burial scenarios. In conclusion, the distribution of the epidemic is arguably a function of population density/distribution, transportation networks, and the chaos associated with the concurrent civil war. Administrative responses to the epidemic likely had a variable, albeit limited, effect in the central lowlands. More peripheral cities, such as Aberdeen, while also employing sophisticated plague prevention measures, were perhaps initially spared simply due to their distance from the central plague belt. It is unclear if a general fear of the dead and contracting the Pest from plague victims can be used to characterise mid-17th century Scottish public opinion. Mass burial appears to have been a practical approach to the logistical problems mass mortality presented, while many instances of normative burial treatment can also be seen.
