Nevada ( , nə-VAD-ə; Spanish: [ne.ˈβa.ða] ) is a landlocked state in the Western United States. It is also sometimes placed in the Mountain West and Southwestern United States. It borders Idaho to the northeast, Oregon to the northwest, California to the west, Arizona to the southeast, and Utah to the east. Nevada is the seventh-most extensive and the 31st-most populous U.S. state. Nearly three-quarters of Nevada's population live in Clark County, which contains the Las Vegas–Paradise metropolitan area. Nevada's capital is Carson City. Las Vegas is the largest city in the state.
Nevada is officially known as the "Silver State" because of the importance of silver to its history and economy. It is also known as the "Battle Born State" because it achieved statehood during the Civil War; as the "Sagebrush State", for the native plant of the same name; and as the "Sage-hen State". Native Americans of the Paiute, Shoshone, and Washoe tribes inhabit what is now Nevada. The first Europeans to explore the region were Spanish. They called the region Nevada (snowy) because of the snow which covered the mountains in winter, similar to the Sierra Nevada in Spain. The area formed from mostly Alta California and part of Nuevo México's territory within the Viceroyalty of New Spain, which gained independence as Mexico in 1821. The United States annexed the area in 1848 after its victory in the Mexican–American War, and it was incorporated as part of the New Mexico and Utah Territory in 1850. The discovery of silver at the Comstock Lode in 1859 led to a population boom that became an impetus to the creation of Nevada Territory out of western Utah Territory in 1861. Nevada became the 36th state on October 31, 1864, as the second of two states added to the Union during the Civil War (the first being West Virginia).
Nevada is known for its libertarian laws. In 1940, with a population of just over 110,000 people, Nevada was by far the least-populated state, with less than half the population of the next least-populous state, Wyoming. However, legalized gambling and lenient marriage and divorce laws transformed Nevada into a major tourist destination in the 20th century. Nevada is the only U.S. state where prostitution is legal, though it is illegal in its most populated regions – Clark County (Las Vegas), Washoe County (Reno) and Carson City (which, as an independent city, is not within the boundaries of any county). The tourism industry remains Nevada's largest employer, with mining continuing as a substantial sector of the economy: Nevada is the fourth-largest producer of gold in the world.
The state's name means "snowy" in Spanish, referring to Nevada's extensive number of mountain ranges capped with snow in winter, which help make Nevada among the highest US states by mean altitude. These include the Carson Range portion of the Sierra Nevada (and about 1/3 of Lake Tahoe by surface area), as well as the Toiyabe Range, Ruby Mountains, and Spring Mountains (which exemplify the sky islands of the Great Basin montane forests), in western, central, northeastern, and southern Nevada, respectively. Nevada is the driest U.S. state, both lying in the rain shadow of the Sierra Nevada and receiving among the highest solar irradiance of any U.S. state, and is thus largely desert and semi-arid. Nevada comprises the majority of the Great Basin, as well as a large portion of the Mojave Desert. In 2020, 80.1% of the state's land was managed by various jurisdictions of the U.S. federal government, both civilian and military. Droughts in Nevada, which are influenced by climate change, have been increasing in frequency and severity, putting a further strain on Nevada's water security. Nonetheless, Nevada is among the leaders in adapting to climate change, including via climate science at Desert Research Institute, extensive water recycling in the Las Vegas metropolitan area, voter-mandated investment in solar power, hosting leading electric vehicle manufacturing ecosystem resources at the largest industrial park in the U.S., and developing the largest lithium mine in the U.S. for use in electric batteries.
The name "Nevada" comes from the Spanish adjective nevada ([neˈβaða]), meaning "snowy" or "snow-covered". The state takes its name from the Nevada Territory, which in turn may have been named either for the Sierra Nevada (Spain) mountain range, or for the Sierra Nevada mountain range lying mostly in neighboring California, or just as a descriptive name for a range of snowy mountains. A number of other mountain ranges in Spanish-speaking countries are also named "Sierra Nevada".
Nevadans typically pronounce the second syllable with the "a" of "apple" (). Despite this, some people from outside of the state pronounce it with the "a" of "palm" (). Although the quality, but not the length, of the latter pronunciation is closer to the Spanish pronunciation (Spanish /a/ is open central [ä], whereas American English /ɑː/ varies from back [ɑː] to central [äː]), it is not the pronunciation used by Nevadans. State Assemblyman Harry Mortenson proposed a bill to recognize the alternative pronunciation of Nevada, though the bill was not supported by most legislators and never received a vote. The Nevadan pronunciation is the one used by the state legislature. At one time, the state's official tourism organization, TravelNevada, stylized the name of the state as "Nevăda", with a breve over the a indicating the locally preferred pronunciation, which was also available as a license plate design until 2007.
Before the arrival of Europeans, the earliest inhabitants were Indigenous tribes including the Goshute, Southern Paiute, Mohave, and Wašišiw (Washoe people).
Francisco Garcés was the first European in the area. Nevada was annexed as a part of the Spanish Empire in the northwestern territory of New Spain. Administratively, the area of Nevada was part of the Commandancy General of the Provincias Internas in the Viceroyalty of New Spain. Nevada became a part of Alta California (Upper California) province in 1804 when the Californias were split. With the Mexican War of Independence won in 1821, the province of Alta California became a territory (state) of Mexico, with a small population.
Jedediah Smith entered the Las Vegas Valley in 1827, Peter Skene Ogden traveled the Humboldt River in 1828, and in 1829 a merchant from Nuevo México named Antonio Armijo streamlined travel along the Old Spanish Trail. Chronicling Armijo's route his scout Raphael Rivera was the first to name Las Vegas, in an 1830 report to governor José Antonio Chaves. Following the suggestions by Rivera of a spring, on the published expedition's map, located in the Las Vegas area John C. Frémont set up camp in Las Vegas Springs in 1844. In 1847, Mormons established the State of Deseret, claiming all of Nevada within the Great Basin and the Colorado watershed. They built the first permanent settlement in what is now Nevada, called Mormon Station (now Genoa), in 1851. Additionally, in June 1855, William Bringhurst and 29 other Mormon missionaries built the first permanent structure, a 150-foot square adobe fort, northeast of downtown Las Vegas, converging on the Spanish and Mormon Roads. The fort remained under Salt Lake City's control until the winter of 1858–1859, and the route remained largely under the control of Salt Lake City and Santa Fe tradespersons.
As such, these pioneers laid the foundation for the emergence of the initial settlements between the Sierra Nevadas and Mojave Desert and within the Las Vegas Valley. The enduring influence of New Mexico and Utah culture has since profoundly impacted Nevada's identity, manifesting through New Mexican cuisine and Mormon foodways or New Mexican and Mormon folk musics, into the fabric of Nevada's own cultural landscape.
As a result of the Mexican–American War and the Treaty of Guadalupe Hidalgo, Mexico permanently lost Alta California in 1848. The new areas acquired by the United States continued to be administered as territories. As part of the Mexican Cession (1848) and the subsequent California Gold Rush that used Emigrant Trails through the area, the state's area evolved first as part of the Utah Territory and New Mexico Territory, then the Nevada Territory (March 2, 1861; named for the Sierra Nevada).
