Assiniboine
The Assiniboine (Nakoda) were a Siouan-speaking people who had separated from the Yanktonai Sioux centuries earlier and occupied a vast territory across the northern Great Plains, ranging from present-day Montana into Saskatchewan and Manitoba. Lewis and Clark did not encounter the Assiniboine directly during the main journey, but learned of them extensively during the winter of 1804–1805 at Fort Mandan, where the Mandan and Hidatsa described them as important trading partners and occasional adversaries. The Assiniboine were prominent participants in the extensive northern Plains trade network, exchanging European goods obtained from British posts on the Assiniboine River for corn and horses from the village tribes.
