Idaho Overview

Abbreviated as ID by ABBREVIATIONFINDER, Idaho is a US state in the Pacific Northwest region of the United States. The state’s largest city and capital is Boise. The inhabitants are called “Idahoans”. Idaho became US territory through the Oregon Treaty and joined the union on July 3, 1890 as the 43rd state.

Idaho is a mostly mountainous state with an area barely less than half of Sweden. It is a landlocked state surrounded by the states of Washington, Oregon, Nevada, Utah, Wyoming, Montana and the Canadian province of British Columbia. A network of dams and locks on the Columbia River and Snake River makes the city of Lewiston the port furthest from the west coast of the continental United States.

According to the 2010 United States Census Bureau estimate, Idaho had a population of 1,567,582. The state’s abbreviation is ID. The state’s motto is Esto Perpetua ( Latin for “May you [or she, that is, the state of Idaho] remain forever”). Idaho is the 14th largest state on the surface. Idaho’s nickname is Gem State because almost all known gems have been found there. The official gemstone of the state is star garnet (garnet with asterism ), which except in the Himalayas ( India) almost only found in Idaho. Small amounts of star grenades have also been found in Russia, Brazil and North Carolina.


Idaho is an important state from an agricultural point of view. Almost a third of all potatoes in the United States are grown there. McDonalds, one of the world’s largest potato buyers (of which 140-150 million kilos per year from Idaho), uses the varieties: Russet Burbank, Shepody and Pentland Dell, which are mostly grown in Idaho.

Other important industries in Idaho are the food industry, timber, wood products, machinery, chemical products, paper products, electronics manufacturing, as well as silver and other mining operations. The world’s largest raw material for processed cheese is located in Gooding County, Idaho. The factory has a capacity of 120,000 tonnes per year and belongs to the Glanbia group (Ireland-owned international company group). The Idaho National Laboratory (INL), a state-run facility for nuclear research, is also an important part of Eastern Idaho’s economy. In Idaho, there are three plants owned by Anheuser-Busch InBev, the world’s largest beer producer, which contribute a large portion of all the malt used by breweries across the United States.

The region occupied today by Idaho originally belonged to the Country of Oregon, a vast territory that was claimed by the United States, Great Britain, Spain and Russia during the first quarter of the 19th century. The indigenous peoples that inhabited the region were the Shoshone, the Bannock, the Nez Percé and the Kutenai. The first white explorers were the Americans Meriwether Lewis and William Clark, who toured these lands in 1805 and 1806. They were followed by fur traders from British and American companies. The British took full control during the War of 1812, but in 1818 Britain allowed the United States to occupy the region. Spain and Russia they gave up their claims to the territory in 1819 and 1824, respectively. Business in Idaho expanded with the construction of Fort Hall near Pocatello in 1834. The commercial rivalry between the British and the Americans ended in 1846, with the signing of the treaty by which Great Britain and the United States reorganized jurisdiction over the entire region south of the 49th parallel. In 1861, a large-scale migratory movement began in Idaho., consequence of the discovery of gold in a tributary of the Clearwater River. On March 4, 1863, the United States government constituted the Territory of Idaho, consisting of present-day Idaho, Wyoming, Montana, and part of South Dakota, North Dakota and Nebraska. The current borders of Idaho are the result of the formation of the Territories of Montana, in 1864, and Wyoming, in 1868.

Growth and development

The territorial economy grew steadily during the period between 1870 and 1880. Cattleraising became their main activity. Railway lines were built and rich new mineral deposits were discovered. Between 1870 and 1880, various groups of Indians, offended by the invasion of their former dominions, attacked the colonies of the Idaho Territory. Federal troops put down these uprisings and the Indians were finally confined to reservations. In 1890, Idaho became the 43rd state in the Union. Already then it was the main producer of silver and began to develop an important industry commercial timber. Federal irrigation projects turned large desert areas into farmland, causing great agricultural growth during World War I and World War II. In 1951, for the first time in history, a nuclear reactor test base generated electricity from atomic energy (see Nuclear Energy). By the mid-1970s, the base had become a major engineering laboratory under the jurisdiction of the United States Department of Energy. Meanwhile, due to the popularity of mountainous regions such as Sun Valley, Idaho’s tourism industry experienced a boom, which has continued into the 1990s. and it has motivated the development of new tourist centers.
