. Willing claimed that the name was derived from a Shoshone term meaning "the sun comes from the mountains" or "gem of the mountains", but it was revealed later that there was no such term and Willing claimed that he had been inspired to coin the name when he met a little girl named ''Ida''. Since the name appeared to be fabricated, the U.S. Congress ultimately decided to name the area

Regardless, part of Washington Territory, including Idaho County, was used to create Idaho Territory in 1863. Idaho Territory would later change its boundaries to the area that became the U.S. state.

History

Humans may have been present in the Idaho area as long as 14,500 years ago. Excavations at Wilson Butte Cave near Twin Falls in 1959 revealed evidence of human activity, including arrowheads, that rank among the oldest dated artifacts in North America. American Indian peoples predominant in the area included the Nez Percé in the north and the Northern and Western Shoshone in the south. A Late

The discoverers emphasized that they possess similarities with tools and artifacts discovered in Japan that date from 16,000 to 13,000 years ago. The discovery also showed that the first people might not have come to North America by land, as previously theorized. On the contrary, they probably came through the water, using a

Energy

As of 2017, the primary energy source in Idaho was hydropower, and the energy companies had a total retail sales of 23,793,790 megawatt hours (MWh). As of 2017, Idaho had a regulated electricity market, with the Idaho Public Utilities Commission regulating the three major utilities of Avista Utilities, Idaho Power, and

. Idaho imports most of the energy it consumes. Imports account for more than 80% of energy consumption, including all of Idaho's natural gas and petroleum supplies and more than half of its electricity. Of the electricity consumed in Idaho in 2005, 48% came from hydroelectricity, 42% was generated by burning coal and 9% was generated by burning natural gas. The remainder came from other renewable sources, such as wind. The state's river basins allow hydroelectric power plants to provide 556,000 MWh, which amounts to about three-fourths of Idaho's electricity generated in the state. Washington State provides most of the natural gas used in Idaho through one of the two major pipeline systems supplying the state. Although the state relies on out-of-state sources for its entire natural gas supply, it uses natural gas-fired plants to generate 127,000 MWh, or about ten percent of its output. Coal-fired generation and the state's small array of wind turbines supplies the remainder of the state's electricity output. The state produces 739,000 MWh but still needs to import half of its electricity from out-of-state to meet demand. In addition, Idaho also has the 6th fastest growing population in the United States with the population expected to increase by 31% from 2008 to 2030. This projected increase in population will contribute to a 42% increase in demand by 2030, further straining Idaho's finite hydroelectric resources. Idaho has an upper-boundary estimate of development potential to generate 44,320 GWh/year from 18,076 MW of wind power, and 7,467,000 GWh/year from

Idaho Code and Statutes

All of Idaho's state laws are contained in the Idaho Code and Statutes. The code is amended through the legislature with the approval of the governor. Idaho still operates under its original (1889) state constitution.

State government

The constitution of Idaho provides for three branches of government: the executive, legislative and judicial branches. Idaho has a bicameral legislature, elected from 35 legislative districts, each represented by one senator and two representatives. Since 1946, statewide elected constitutional officers have been elected to four-year terms. They include:

, many Midwestern and Southern Democrats moved to the Idaho Territory. As a result, the early territorial legislatures were solidly Democrat-controlled. In contrast, most of the territorial governors were appointed by

presidents and were Republicans. This led to sometimes-bitter clashes between the two parties, including a range war with the Democrats backing the sheepherders and the Republicans the cattlemen, which ended in the "Diamondfield" Jack Davis murder trial. In the 1880s, Republicans became more prominent in local politics. In 1864, Clinton DeWitt Smith removed the territorial seal and the state constitution from a locked safe, and took them to Boise. This effectively moved the capital from where they were stored ( Lewiston, Idaho) to the current capital, Boise. Since statehood, the Republican Party has usually been the dominant party in Idaho. At one time, Idaho had two Democratic parties, one being the mainstream and the other called the Anti-Mormon Democrats, lasting into the early 20th century. In the 1890s and early 1900s, the Populist Party enjoyed prominence, while the Democratic Party maintained a brief dominance in the 1930s during the Great Depression. Since World WarII, most statewide-elected officials have been Republicans, though the Democrats did hold the majority in the House (by one seat) in 1958 and the governorship from 1971 to 1995. Idaho Congressional delegations have also been generally Republican since statehood. Several Idaho Democrats have had electoral success in the
