Wyoming ( wy-OH-ming) is a landlocked state in the Mountain West subregion of the Western United States. It borders Montana to the north and northwest, South Dakota and Nebraska to the east, Idaho to the west, Utah to the southwest, and Colorado to the south. With an estimated population of 587,618 as of 2024, Wyoming is the least populous state despite being the tenth-largest by area, and it has the second-lowest population density.2 It is headquartered in Cheyenne, United States.1 Wikipedia text CC BY-SA 4.0

The state capital and most populous city is Cheyenne.2

The story

History

Several Native American groups originally inhabited the region today known as Wyoming. The Crow, Arapaho, Lakota, and Shoshone were but a few of the original inhabitants European explorers encountered when they first visited the region. What is now southwestern Wyoming was claimed by the Spanish Empire, which extended through the Southwest and Mexico. With Mexican independence in 1821, it was considered part of Alta California. U.S. expansion brought settlers who fought for control. Mexico ceded these territories after its defeat in 1848 in the Mexican–American War.

From the late 18th century, French-Canadian trappers from Québec and Montréal regularly entered the area for trade with the tribes. French toponyms such as Téton and La Ramie are marks of that history.

American John Colter first recorded a description in English of the region in 1807. He was a member of the Lewis and Clark Expedition, which was guided by French Canadian Toussaint Charbonneau and his young Shoshone wife, Sacagawea. At the time, Colter's reports of the Yellowstone area were considered fictional. On a return from Astoria, Robert Stuart and a party of five men discovered South Pass in 1812.

The Oregon Trail later followed that route as emigrants moved to the west coast. In 1850, mountain man Jim Bridger first documented what is now known as Bridger Pass. Bridger also explored Yellowstone, and filed reports on the region that, like Colter's, were largely regarded at the time as tall tales. The Union Pacific Railroad constructed track through Bridger Pass in 1868. It was used as the route for construction of Interstate 80 through the mountains 90 years later.

After the Union Pacific Railroad reached Cheyenne in 1867, population growth was stimulated. The federal government established the Wyoming Territory on July 25, 1868. Lacking significant deposits of gold and silver, unlike mineral-rich Colorado, Wyoming did not have such a population boom. But South Pass City had a short-lived boom after the Carissa Mine began producing gold in 1867. Copper was mined in some areas between the Sierra Madre Mountains and the Snowy Range near Grand Encampment.

Once government-sponsored expeditions to the Yellowstone country began, Colter's and Bridger's descriptions of the region's landscape were confirmed. In 1872, Yellowstone National Park was created as the world's first, to protect this area. Nearly all of the park lies within the northwestern corner of Wyoming.

On December 10, 1869, territorial Governor John Allen Campbell extended the right to vote to women, making Wyoming the first territory to do so, and upon statehood became the first state to grant women's suffrage. Women first served on juries in Wyoming (Laramie in 1870). Wyoming was also a pioneer in welcoming women into electoral politics. It had the first female court bailiff (Mary Atkinson, Laramie, in 1870), and the first female justice of the peace in the country (Esther Hobart Morris, South Pass City, in 1870). In 1924, Wyoming was the first state to elect a female governor, Nellie Tayloe Ross, who took office in January 1925. Due to its civil-rights history, one of Wyoming's state nicknames is "The Equality State", and the official state motto is "Equal Rights".

Wyoming's constitution also included a pioneering article on water rights. Bills for Wyoming Territory's admission to the union were introduced in both the U.S. Senate and U.S. House of Representatives in December 1889. On March 27, 1890, the House passed the bill and President Benjamin Harrison signed Wyoming's statehood bill; Wyoming became the 44th state in the union on July 10, 1890.

Wyoming was the location of the Johnson County War of 1892, which erupted between competing groups of cattle ranchers. The passage of the Homestead Act led to an influx of small ranchers. A range war broke out when either or both of the groups chose violent conflict over commercial competition in the use of the public land.

Political history

Wyoming's political history defies easy classification. The state was the first to grant women the right to vote and to elect a woman governor. On December 10, 1869, John Allen Campbell, the first Governor of the Wyoming Territory, approved the first law in United States history explicitly granting women the right to vote. This day was later commemorated as Wyoming Day. On November 5, 1889, voters approved the first constitution in the world granting full voting rights to women.

While the state elected notable Democrats to federal office in the 1960s and 1970s, politics have become decidedly more conservative since the 1980s as the Republican Party came to dominate the state's congressional delegation. Today, Wyoming is represented in Washington by its two Senators, John Barrasso and Cynthia Lummis, and its one member of the House of Representatives, Congresswoman Harriet Hageman. All three are Republicans; a Democrat has not represented Wyoming in the Senate since 1977 or in the House since 1978. The state has not voted for a Democrat for president since 1964, one of only eight times since statehood. In the 2004 presidential election, George W. Bush won his second-largest victory, with 69% of the vote. Former Vice President Dick Cheney was a Wyoming resident and represented the state in Congress from 1979 to 1989.

The last time a Democrat won a statewide election in Wyoming was in 2006, when Democratic governor Dave Freudenthal was re-elected to a second term by a wide margin, winning every county in the state. For 19 of Wyoming's 23 counties, 2006 marked the last time that they voted for the Democratic nominee in a statewide race. Of the remaining 4, Sweetwater County last voted Democratic in the 2008 U.S. House race and Laramie County last voted Democratic in the 2014 Superintendent of Public Instruction race, leaving Teton and Albany as the only counties that Democrats are able to win. Teton, which is composed of affluent resort communities, is reliably Democratic, except in Republican landslides like the 2022 gubernatorial election; Albany, which contains the college town of Laramie, is more competitive.

Republicans are dominant at the state level. They have held a majority in the state senate continuously since 1936 and in the state house since 1964, though Democrats held the governorship for all but eight years between 1975 and 2011. Uniquely, Wyoming elected Democrat Nellie Tayloe Ross as the first woman in United States history to serve as state governor. She served from 1925 to 1927, winning a special election after her husband, William Bradford Ross, unexpectedly died a little more than a year into his term.

Wyoming retains the death penalty. Authorized methods of execution include the gas chamber.

Location and size

As specified in the designating legislation for the Territory of Wyoming, Wyoming's borders are lines of latitude 41°N and 45°N, and longitude 104°3'W and 111°3'W (27 and 34 west of the Washington Meridian) – a geodesic quadrangle. Wyoming is one of only three states (the others being Colorado and Utah) to have borders defined by only "straight" lines. Due to surveying inaccuracies during the 19th century, Wyoming's legal border deviates from the true latitude and longitude lines by up to one-half mile (0.80 km) in some spots, especially in the mountainous region along the 45th parallel. Wyoming is bordered on the north by Montana, on the east by South Dakota and Nebraska, on the south by Colorado, on the southwest by Utah, and on the west by Idaho. It is the tenth largest state in the United States in total area, containing 97,814 square miles (253,340 km2) and is made up of 23 counties. From the north border to the south border, it is 276 miles (444 km); and from the east to the west border is 365 miles (587 km) at its south end and 342 miles (550 km) at the north end.

Metropolitan areas

The United States Census Bureau has defined two metropolitan statistical areas (MSA) and eight micropolitan statistical areas (MiSA) for the state. In 2020, 31.3% of Wyomingites lived in either of the metropolitan statistical areas, and 80.4% lived in either a metropolitan or a micropolitan area.
