Explanation:Archaeological evidence indicates that prehistoric Indian settlements existed in Nevada more than 20,000 years ago. Cave dwellers left picture writings on rocks in southern Nevada, and Basketmakers and Pueblo Indians also flourished there. Explorers of the early 1800s found Mojave, Paiute, Shoshone, and Washoe groups at various locations within Nevada.
Explorers and settlers
Missionaries and fur traders were in the vanguard of the exploration of the Nevada area. The missionary travels of Francisco Garcés from New Mexico to California in 1775–76 were imitated by other Spanish Franciscans. In 1825 Hudson’s Bay Company trappers explored the northern and central region, and two years later Jedediah Smith led a party of American traders into the Las Vegas Valley and across the Great Basin. By 1830 the Old Spanish Trail was bringing traders to the area from Santa Fe and Los Angeles, and in 1843 and 1845 John C. Frémont’s explorations with Kit Carson publicized the Great Basin and the Sierra Nevada region. During the 1840s pioneers followed the Humboldt Valley–Donner Pass route to the Pacific Coast, and the Gold Rush of 1849 greatly expanded migration through Nevada to California.
Nevada became the 36th state on October 31, 1864, after telegraphing the Constitution of Nevada to the Congress days before the November 8 presidential election (the largest and costliest transmission ever by telegraph). Statehood was rushed to help ensure three electoral votes for Abraham Lincoln's reelection and add to the Republican congressional majorities.[1]
