From 1696 to 1700, Native communities from the Atlantic Coast to the Mississippi Valley suffered catastrophic death tolls because of smallpox. The other diseases that then followed in smallpox’s wake devastated the indigenous societies. Kelton found, however, that such biological catastrophes did not occur simply because the region’s Natives lacked immunity. Over the last half of the seventeenth century, the colonies of Virginia and South Carolina had integrated the Southeast into a larger Atlantic world that carried an unprecedented volume of people, goods, and ultimately germs into indigenous villages. Kelton shows that English commerce in Native slaves in particular facilitated the spread of smallpox and made indigenous peoples especially susceptible to infection and mortality as intense violence forced malnourished refugees to huddle in germ-ridden, compact settlements. By 1715 the Native population had plummeted, causing a collapse in the very trade that had facilitated such massive depopulation.
