Between then and the creation of the Idaho Territory on March 4, 1863, at Lewiston, parts of the present-day state were included in the Oregon, Washington, and Dakota Territories. The new territory included present-day Idaho, Montana, and most of Wyoming.
The Lewis and Clark expedition crossed Idaho in 1805 on the way to the Pacific and in 1806 on the return, largely following the Clearwater River both directions. The first non-indigenous settlement was Kullyspell House, established on the shore of Lake Pend Oreille for fur trading in 1809 by David Thompson of the North West Company. In 1812 Donald Mackenzie, working for the Pacific Fur Company at the time, established a post on the lower Clearwater River near present-day Lewiston. This post, known as “MacKenzie’s Post” or “Clearwater”, operated until the Pacific Fur Company was bought out by the North West Company in 1813, after which it was abandoned. The first attempts at organized communities, within the present borders of Idaho, were established in 1860. The first permanent, substantial incorporated community was Lewiston in 1861.
After some tribulation as a territory, including the chaotic transfer of the territorial capital from Lewiston to Boise, disenfranchisement of Mormon polygamists upheld by the U.S. Supreme Court in 1877, and a federal attempt to split the territory between Washington Territory which gained statehood in 1889, a year before Idaho, and the state of Nevada which had been a state since 1864, Idaho achieved statehood in 1890.
Idaho was one of the hardest hit of the Pacific Northwest states during the Great Depression. Prices plummeted for Idaho’s major crops: in 1932 a bushel of potatoes brought only $.10 compared to $1.51 in 1919, while Idaho farmers saw their annual income of $686 in 1929 drop to $250 by 1932.
In recent years, Idaho has expanded its commercial base as a tourism and agricultural state to include science and technology industries. Science and technology have become the largest single economic center, over 25% of the state’s total revenue, within the state and are greater than agriculture, forestry and mining combined.
Economy:
Idaho is an important agricultural state, producing nearly one-third of the potatoes grown in the United States. All three varieties of wheat, dark northern spring, hard red, and soft white are grown in the state. Nez Perce County is considered a premier soft white growing locale.
Important industries in Idaho are food processing, lumber and wood products, machinery, chemical products, paper products, electronics manufacturing, silver and other mining, and tourism. The world’s largest factory for barrel cheese, the raw product for processed cheese is in Gooding, Idaho. It has a capacity of 120,000 metric tons per year of barrel cheese and belongs to the Glanbia group. The Idaho National Laboratory (INL) is the largest Department of Energy facility in the country by area. INL is an important part of the eastern Idaho economy. Idaho also is home to three facilities of Anheuser-Busch which provide a large part of the malt for breweries across the nation.
