I want to know the answer to the following question:
What epidemic resulted in numerous deaths between the 1830s and 1860s?
All the background I'm provided with is that "All three of these peoples, as well as other indigenous peoples of the Pacific Northwest Coast, experienced smallpox outbreaks from the late 18th through the mid-19th century, with the most devastating epidemics occurring in the 1830s and 1860s, resulting in high fatalities and social disruption.". Is that enough to answer the question?
Answer: yes
