Owyhee County is part of the Boise metropolitan area and contains slightly more than half of the Duck Valley Indian Reservation, which extends over the Nevada border, into Elko County. The majority of the federally recognized Shoshone-Paiute Tribe that is associated with this reservation lives on the Nevada side; its tribal center is in Owyhee, Nevada.
This area was the territory of Western Shoshone, Northern Paiute, and Bannock peoples and their ancestors for thousands of years prior to the arrival of European settlers. Settler interests in securing land and resources spurred conflict and led to the indigenous peoples being forced onto reservations.
On December 31, 1863, Owyhee County became the first county organized by the Idaho Territory Legislature. While Boise, Idaho, Nez Perce, and Shoshone counties were organized under the laws of Washington Territory, they were not recognized by the Idaho Territory until February 1864.[5][6][7] The original county seat at Ruby City was moved to nearby Silver City in 1867.[8]
Owyhee County's original boundary was the portion of Idaho Territory south of the Snake River and west of the Rocky Mountains.[9] Less than a month after the creation of Owyhee County, Oneida County was formed in January 1864 from the eastern portion of the county. The formation of Cassia County in 1879 took further territory in the east.
Owyhee County's history is closely linked to the mining boom that dominated Idaho Territory in the second half of the 19th century.[4] Silver City and Ruby City developed as boom towns. At its height in the 1880s, Owyhee County was among the most populous places in Idaho. Today it is among the least populous, at 1.4 persons per square mile (0.54 persons/km2).
Because of pressure from miners and settlers, the federal government made a treaty in 1877 with the Western Shoshone to cede land, and established what is now known as the Duck Valley Indian Reservation in this county and across the border in Elko County, Nevada. The reservation was expanded in 1886 to accommodate people of the Northern Paiute. In the 20th century, the tribes combined and are federally recognized as a single government; the majority of the people live on the Nevada side of the reservation.
There were two railroad lines extending into Owyhee County, the first was the Boise Nampa & Owyhee Railroad which built starting in 1896 from Nampa, Idaho south towards Melba, Idaho and eventually across the Snake River into Owyhee County in 1897, whereupon it crossed Rabbit Creek before arriving in Murphy, Idaho. The first train into Murphy occurred in 1899. The Boise, Nampa & Owyhee Railroad was acquired by the Idaho Northern Railroad in 1907; the line was taken over by the Oregon Short Line Railroad in 1913 following their purchase of the Idaho Northern Railroad, after which it became known as the Murphy Branch line. Daily passenger service to Murphy was discontinued in 1942. By 1947, shipping animals out of Murphy was no longer profitable for the railroad. The Murphy portion of the line was abandoned in 1947. In the 1950s, trucks and highways became the dominant mode of transportation. The last train left Melba in 1994, and all rails were torn out in that same year.
The second railroad line was the Oregon Shortline Railroad which built south from Nyssa Oregon beginning in 1911, passing through Adrian Oregon the line ended after 25 miles in Homedale Idaho, in 1922 it was extended Marsing Idaho to accommodate additional agricultural traffic. In 1970, the Marsing and Homedale depots were closed by Union Pacific. In 1987, with declining carload, Union Pacific offered the line for sale but no buyers were found. Following the closure of the lumber mill in Homedale in the early 1990s, the Homedale branch (now reduced to the status of an "industrial lead") generated a total of 49 carloads in 1995 and 42 in 1996. In 1997, Union Pacific filed for permission to abandon the Idaho portion of the line and received no formal protest, the tracks were ripped up the following year.[10][11]
Owyhee County gained its present boundaries in 1930 after an election approved moving a portion of it near Glenns Ferry and King Hill to neighboring Elmore County.[12] In 1934, the county seat was moved from the nearly abandoned Silver City to its present location in Murphy. In the 21st century, both Silver City and Ruby City are ghost towns, remnant of the mining boom.
The name "Owyhee" derives from an early anglicization of the Hawaiian term "Hawaii". When James Cook encountered what he named the Sandwich Islands (now the Hawaiian Islands) in 1778, he found them inhabited by Native Hawaiians, whom the Anglo-Americans referred to as "Owyhees". Noted for their hardy physique and maritime skills, numerous Native Hawaiians were hired as crew members aboard European and American vessels. Many Native Hawaiians sailed to the American Northwest coast and found employment along the Columbia River, where they joined trapping expeditions or worked at some of the fur trading posts.
In 1819, three Native Hawaiians joined Donald Mackenzie's Snake expedition, which went out annually into the Snake country for the North West Company, a Montreal-based organization of Canadian fur traders. The three Hawaiians left the main party during the winter of 1819–1820 to explore the then unknown terrain of what since has been called the Owyhee River and mountains. They disappeared and were presumed dead; no further information regarding their whereabouts has been found. In memory of these Native Hawaiians, British fur trappers started to call the region "Owyhee" and the name stuck.[13][14]
According to the U.S. Census Bureau, the county has a total area of 7,697 square miles (19,940 km2), of which 7,666 square miles (19,850 km2) is land and 31 square miles (80 km2) (0.4%) is water.[15] It is the second-largest county in Idaho by area.
Nearly all of the county is high intermountain desert, with plentiful sagebrush and basalt canyons. The Owyhee Mountains in the west dominate the landscape, with Hayden Peak reaching 8,403 feet (2,561 m) above sea level. The lowest elevation is at the county's northwest corner, where the Snake River is just above 2,000 feet (610 m) at the Oregon border. The Snake forms most of the county's northern border from Oregon to just west of Glenns Ferry in Elmore County. A tributary of the Snake is the Bruneau River, which flows north from Nevada through the eastern section of the county. The Owyhee River starts in the southwestern part of the county and flows westward into Oregon; it eventually enters the Snake at the state border, south of Nyssa.

Although Owyhee County was amongst the most Democratic in the state in its early history, it has like most of Idaho gradually turned overwhelmingly Republican. In no presidential election since 1940 has the county selected the Democratic candidate, and no Democrat since Jimmy Carter in 1976 has won more than one-third of the county's vote.[citation needed]
