Vaccines
I’m reading Lakota Power: A New History of Indigenous Power, by Pekka Hamalainen. The Finnish author, who teaches at Oxford, has written previously about the Cheyenne, and in this book chronicles the movement of the Sioux out of the northern woodlands, south and west across the plains and into the Black Hills.
The Lakota, one of seven main councils of the Sioux, seized the day with guns and steel provided by the fur trade and feral horses that roamed northward after a 1680s setback to Spanish ambitions in the Southwest. Horses and the fur trade were the fuels of Lakota expansion and tribal rivalries across the middle of the new country—expanded greatly by the Louisiana Purchase.
It wasn’t an easy expansion for the Americans, with British and French fur traders to the north, and Spanish, French, and American factions competing for dominance on the Missouri and Mississippi and access to the larger trade world through St. Louis and New Orleans.
In 1832, in an attempt to thwart British ambitions in the region, the Americans provided smallpox vaccine to the Lakota and a few other Siouxan groups. That same year, 4000 Pawnees, half of their population, died with smallpox. Other Indian tribes were decimated as well. The smallpox vaccine abetted the rising strength of the Lakota across the plains—and maybe helped stall the British, whose trade was with the Hidatsa and other tribes to the north, with no easy access to eastern markets.
The British Hudson’s Bay Company would keep pushing west across what is now southern Canada and the bordering US—looking for access to the Pacific and another route for its trade.
