What happened
Jesuit missionaries led by Jean de Brebeuf established missions among the Wendat (Huron) around Georgian Bay beginning in the 1620s and 1630s, seeking to convert a confederacy Champlain had estimated at roughly 25,000 to 30,000 people. Between 1634 and 1642, a series of epidemics, including smallpox combined with dysentery in 1634, a severe influenza in 1636, and further smallpox in 1639, reduced the Wendat to about 9,000 people. The Jesuits themselves, having grown up exposed to these diseases in Europe, were largely immune and unknowingly carried infection between villages as they travelled. Wendat communities increasingly blamed the missionaries for the epidemics, and Brebeuf recorded that the outbreaks badly slowed conversions even as the death toll mounted.
Why it matters
The epidemic losses gutted Wendat military and economic strength at the exact moment the Haudenosaunee to the south, armed through Dutch trade, were escalating raids for control of the fur trade, leaving Huronia unable to withstand the attacks that would destroy it within the decade.
How we know
The Jesuit Relations, annual reports Jesuit missionaries sent back to France, describe the epidemics, population estimates, and Wendat reactions in detail and are the primary documentary source used by the Dictionary of Canadian Biography and the Canadian Encyclopedia for this period.
