Idaho: Early Explorers and Fur Traders

Probably the first nonnatives to enter the area that is now Idaho were members of the Lewis and Clark expedition in 1805. They were not far ahead of the fur traders who came to the region shortly thereafter. A Canadian, David Thompson of the North West Company, established the first trading post in Idaho in 1809. The next year traders from St. Louis penetrated the mountains, and Andrew Henry of the Missouri Fur Company established a post near present-day Rexburg, the first American trading post established in the area.

In this period the fortunes of the Idaho region were wrapped up with those of the Columbia River region, and the area encompassed by what is now the state of Idaho was part of Oregon country, held jointly by the United States and Great Britain from 1818 to 1846. Fur traders in an expedition sent out by John Jacob Astor came to the Snake River region to trap for furs after having established (1811) a trading post at Astoria on the Columbia River. In 1821 two British trading companies operating in the Idaho region, the North West Company and the Hudson's Bay Company, were joined together as the Hudson's Bay Company which, after 1824, came into competition with American mountain men also trapping in the area. By the 1840s the two groups had severely depleted the region's fur supply.
