Oklahoma (ⁱ/ˌoʊkləˈhoʊmə/)^[4] (Pawnee: Uukuhuúwa ^[5], Cayuga: Gahnawiyoˀgeh ^[6]) is a state located in the South Central region of the United States of America. Oklahoma is the 20th most extensive and the 28th most populous of the 50 United States. The state's name is derived from the Choctaw words okla and humma, meaning "red people",^[7] and it is known informally by its nickname, The Sooner State. Formed by the combination of Oklahoma Territory and Indian Territory on November 16, 1907, Oklahoma was the 46th state to enter the union. Its residents are known as Oklahomans or, informally "Okies", and its capital and largest city is Oklahoma City.

A major producer of natural gas, oil, and agriculture, Oklahoma relies on an economic base of aviation, energy, telecommunications, and biotechnology.^[8] It has one of the fastest growing economies in the nation, ranking among the top states in per capita income growth and gross domestic product growth.^[9][10] Oklahoma City and Tulsa serve as Oklahoma's primary economic anchors, with nearly 60 percent of Oklahomans living in their metropolitan statistical areas.^[11]

With small mountain ranges, prairie, and eastern forests, most of Oklahoma lies in the Great Plains and the U.S. Interior Highlands—a region especially prone to severe weather.^[12] In addition to having a prevalence of German, Irish, English, Scottish, and Native American ancestry, more than 25 Native American languages are spoken in Oklahoma, the most of any state.^[13] It is located on a confluence of three major American cultural regions and historically served as a route for cattle drives, a destination for southern settlers, and a government-sanctioned territory for Native Americans. As part of the Bible Belt, widespread belief in evangelical Christianity makes it one of the most politically conservative states, though Oklahoma has more voters registered with the Democratic Party than with any other party.^[14]

Etymology[link]

The name Oklahoma comes from the phrase okla humma, literally meaning red people. Choctaw Chief Allen Wright suggested the name in 1866 during treaty negotiations with the federal government regarding the use of Indian Territory, in which he envisioned an all-Indian state controlled by the United States Superintendent of Indian Affairs. Equivalent to the English word Indian, okla humma was a phrase in the Choctaw language used to describe the Native American race as a whole. Oklahoma later became the de facto name for Oklahoma Territory, and it was officially approved in 1890, two years after the area was opened to white settlers.^[7][15][16]

Geography[link]

The state's high plains stretch behind a greeting sign in the Oklahoma Panhandle.

Oklahoma is the 20th-largest state in the United States, covering an area of 69,898 square miles (181,035 km²), with 68,667 square miles (177847 km²) of land and 1,281 square miles (3,188 km²) of water.^[17] It is one of six states on the Frontier Strip, and lies partly in the Great Plains near the geographical center of the 48 contiguous states. Arkansas and Missouri bound it on the east, on the north by Kansas, on the northwest by Colorado, on the far west by New Mexico, and on the south and near-west by Texas.

Topography[link]

Oklahoma is between the Great Plains and the Ozark Plateau in the Gulf of Mexico watershed,^[18] generally sloping from the high plains of its western boundary to the low wetlands of its southeastern boundary.^[19][20] Its highest and lowest points follow this trend, with its highest peak, Black Mesa, at 4,973 feet (1,516 m) above sea level, situated near its far northwest corner in the Oklahoma Panhandle. The state's lowest point is on the Little River near its far southeastern boundary near the town of Idabel, OK, which dips to 289 feet (88 m) above sea level.^[21]

A river carves a canyon in the Wichita Mountains.

Among the most geographically diverse states, Oklahoma is one of four to harbor more than 10 distinct ecological regions, with 11 in its borders – more per square mile than in any other state.^[12] Its western and eastern halves, however, are marked by extreme differences in geographical diversity: Eastern Oklahoma touches eight ecological regions and its western half contains three.^[12]

The Ouachita Mountains cover much of southeastern Oklahoma.

Oklahoma has four primary mountain ranges: the Ouachita Mountains, the Arbuckle Mountains, the Wichita Mountains, and the Ozark Mountains.^[19] Contained within the U.S. Interior Highlands region, the Ozark and Ouachita Mountains mark the only major mountainous region between the Rocky Mountains and the Appalachians.^[22] A portion of the Flint Hills stretches into north-central Oklahoma, and in the state's southeastern corner, Cavanal Hill is regarded by the Oklahoma Tourism & Recreation Department as the world's tallest hill; at 1,999 feet (609 m), it fails their definition of a mountain by one foot.^[23]

The semi-arid high plains in the state’s northwestern corner harbor few natural forests. Oklahoma has a rolling to flat landscape with intermittent canyons and mesa ranges like the Glass Mountains. Partial plains interrupted by small mountain ranges like the Antelope Hills and the Wichita Mountains dot southwestern Oklahoma, and transitional prairie and woodlands cover the central portion of the state. The Ozark and Ouachita Mountains rise from west to east over the state's eastern third, gradually increasing in elevation in an eastward direction.^[20][24] More than 500 named creeks and rivers make up Oklahoma's waterways, and with 200 lakes created by dams, it holds the highest number of artificial reservoirs in the nation.^[23] Most of the state lies in two primary drainage basins belonging to the Red and Arkansas rivers, though the Lee and Little rivers also contain significant drainage basins.^[24]

Flora and fauna[link]

Populations of American Bison inhabit the state's prairie ecosystems.

Forests cover 24 percent of Oklahoma^[23] and prairie grasslands composed of shortgrass, mixed-grass, and tallgrass prairie, harbor expansive ecosystems in the state's central and western portions, although cropland has largely replaced native grasses.^[25] Where rainfall is sparse in the western regions of the state, shortgrass prairie and shrublands are the most prominent ecosystems, though pinyon pines, red cedar (junipers), and ponderosa pines grow near rivers and creek beds in the far western reaches of the panhandle.^[25] Marshlands, cypress forests and mixtures of shortleaf pine, loblolly pine and deciduous forests dominate the state's southeastern quarter, while mixtures of largely post oak, elm, red cedar (Juniperus virginiana) and pine forests cover northeastern Oklahoma.^[24][25][26]

The state holds populations of white-tailed deer, coyotes, bobcats, elk, and birds such as quail, doves, cardinals, bald eagles, red-tailed hawks, and pheasants. In prairie ecosystems, American bison, greater prairie chickens, badgers, and armadillo are common, and some of the nation's largest prairie dog towns inhabit shortgrass prairie in the state's panhandle. The Cross Timbers, a region transitioning from prairie to woodlands in Central Oklahoma, harbors 351 vertebrate species. The Ouachita Mountains are home to black bear, red fox, grey fox, and river otter populations, which coexist with a total of 328 vertebrate species in southeastern Oklahoma. Also, in southeastern Oklahoma lives the American Alligator.^[25]

Protected lands[link]

Mesas rise above one of Oklahoma's state parks.

Oklahoma has 50 state parks,^[27] six national parks or protected regions,^[28] two national protected forests or grasslands,^[29] and a network of wildlife preserves and conservation areas. Six percent of the state's 10 million acres (40,000 km²) of forest is public land,^[26] including the western portions of the Ouachita National Forest, the largest and oldest national forest in the Southern United States.^[30] With 39,000 acres (158 km²), the Tallgrass Prairie Preserve in north-central Oklahoma is the largest protected area of tallgrass prairie in the world and is part of an ecosystem that encompasses only 10 percent of its former land area, once covering 14 states.^[31] In addition, the Black Kettle National Grassland covers 31,300 acres (127 km²) of prairie in southwestern Oklahoma.^[32] The Wichita Mountains Wildlife Refuge is the oldest and largest of nine national wildlife refuges in the state^[33] and was founded in 1901, encompassing 59,020 acres (238.8 km²).^[34] Of Oklahoma's federally protected park or recreational sites; the Chickasaw National Recreation Area is the largest, with 9,898.63 acres (18 km²).^[35] Other sites include the Santa Fe and Trail of Tears national historic trails, the Fort Smith and Washita Battlefield national historic sites, and the Oklahoma City National Memorial.^[28]

Climate[link]

Oklahoma is located in a temperate region and experiences occasional extremes of temperature and precipitation typical in a continental climate.^[36] Most of the state lies in an area known as Tornado Alley characterized by frequent interaction between cold and warm air masses producing severe weather.^[21] An average 54 tornadoes strike the state per year—one of the highest rates in the world.^[37] Because of its position between zones of differing prevailing temperature and winds, weather patterns within the state can vary widely between relatively short distances and can change drastically in a short time.^[21] As an example, on November 11, 1911, the temperature at Oklahoma City reached 83 °F (28 °C) in the afternoon (the record high for that date), then an incoming squall line resulted in a drop to 17 °F (−8 °C) at midnight (the record low for that date); thus, both the record high and record low for November 11 were set on the same day.^[38]

Oklahoma's climate is prime for thunderstorm development.

The humid subtropical climate (Koppen Cfa) of the eastern part of Oklahoma influenced heavily by southerly winds bringing moisture from the Gulf of Mexico, but transitions progressively to a semi-arid zone (Koppen BSk) in the high plains of the Panhandle and other western areas from about Lawton westward less frequently touched by southern moisture.^[36] Precipitation and temperatures fall from east to west accordingly, with areas in the southeast averaging an annual temperature of 62 °F (17 °C) and an annual rainfall of 56 inches (1,420 mm), while areas of the panhandle average 58 °F (14 °C), with an annual rainfall under 17 inches (430 mm).^[21] All of the state frequently experiences temperatures above 100 °F (38 °C) or below 0 °F (−18 °C),^[36] and snowfall ranges from an average of less than 4 inches (10 cm) in the south to just over 20 inches (51 cm) on the border of Colorado in the panhandle.^[21] The state is home to the Storm Prediction Center, the National Severe Storms Laboratory, and the Warning Decision Training Branch, all part of the National Weather Service and located in Norman.^[39] Oklahoma's highest recorded temperature of 120 °F (49 °C) was recorded at Tipton on June 27, 1994 and the lowest recorded temperature of −31 °F (−35 °C) was recorded at Nowata on February 10, 2011.

History[link]

Evidence exists that native peoples traveled through Oklahoma as early as the last ice age,^[42] but the state's first permanent inhabitants settled in communities accentuated with mound-like structures near the Arkansas border between 850 and 1450 AD.^[43][44] Spaniard Francisco Vásquez de Coronado traveled through the state in 1541,^[45] but French explorers claimed the area in the 1700s^[46] and it remained under French rule until 1803, when all the French territory west of the Mississippi River was purchased by the United States in the Louisiana Purchase.^[45]

During the 19th century, thousands of Native Americans were expelled from their ancestral homelands from across North America and transported to the area including and surrounding present-day Oklahoma. The Choctaw was the first of the "Five Civilized Tribes" to be removed from the southeastern United States. The phrase "Trail of Tears" originated from a description of the removal of the Choctaw Nation in 1831, although the term is usually used for the Cherokee removal.^[47] About 17,000 Cherokees – along with approximately 2,000 black slaves owned by Cherokees – were removed from their homes.^[48] The area, already occupied by Osage and Quapaw tribes, was called for the Choctaw Nation until revised Native American and then later American policy redefined the boundaries to include other Native Americans. By 1890, more than 30 Native American nations and tribes had been concentrated on land within Indian Territory or "Indian Country."^[49] Many Native Americans served in the Union and Confederate military during the American Civil War. The Cherokee Nation had an internal civil war.^[50] Slavery in Oklahoma was not abolished until 1866.^[51]

In the period between 1866 and 1899,^[45] cattle ranches in Texas strove to meet the demands for food in eastern cities and railroads in Kansas promised to deliver in a timely manner. Cattle trails and cattle ranches developed as cowboys either drove their product north or settled illegally in Indian Territory.^[45] In 1881, four of five major cattle trails on the western frontier traveled through Indian Territory.^[52] Increased presence of white settlers in Indian Territory prompted the United States Government to establish the Dawes Act in 1887, which divided the lands of individual tribes into allotments for individual families, encouraging farming and private land ownership among native Americans but expropriating land to the federal government. In the process, railroad companies took nearly half of Indian-held land within the territory for outside settlers and for purchase.^[53]

The Dust Bowl sent thousands of farmers into poverty during the 1930s.

Major land runs, including the Land Run of 1889, were held for settlers where certain territories were opened to settlement starting at a precise time. Usually land was open to settlers on a first come first served basis.^[54] Those who broke the rules by crossing the border into the territory before the official opening time were said to have been crossing the border sooner, leading to the term sooners, which eventually became the state's official nickname.^[55]

Deliberations to make the territory into a state began near the end of the 19th century, when the Curtis Act continued the allotment of Indian tribal land. Attempts to create an all-Indian state named Oklahoma and a later attempt to create an all-Indian state named Sequoyah failed but the Sequoyah Statehood Convention of 1905 eventually laid the groundwork for the Oklahoma Statehood Convention, which took place two years later.^[56] On November 16, 1907, Oklahoma was established as the 46th state in the Union.

The bombing of the Alfred P. Murrah Federal Building in Oklahoma City was one of the deadliest acts of terrorism in American history.

The new state became a focal point for the emerging oil industry, as discoveries of oil pools prompted towns to grow rapidly in population and wealth. Tulsa eventually became known as the "Oil Capital of the World" for most of the 20th century and oil investments fueled much of the state's early economy.^[57] In 1927, an Oklahoman businessman Cyrus Avery, known as the "Father of Route 66", began the campaign to create U.S. Route 66. Using a stretch of highway from Amarillo, Texas to Tulsa, Oklahoma to form the original portion of Highway 66, Avery spearheaded the creation of the U.S. Highway 66 Association to oversee the planning of Route 66, based in his hometown of Tulsa.^[58]

Oklahoma also has a rich African American history. There were many black towns that thrived in the early 20th century because of black settlers moving from neighboring states, especially Kansas. The politician Edward P. McCabe encouraged black settlers to come to what was then Indian Territory. He discussed with President Theodore Roosevelt the possibility of making Oklahoma a majority-black state.

By the early 20th century, the Greenwood neighborhood of Tulsa was one of the most prosperous African-American communities in the United States.^[59] Jim Crow laws had established racial segregation since before the turn of the century, but the blacks had created a thriving area.

Social tensions were exacerbated by the revival of the Ku Klux Klan after 1915. The Tulsa Race Riot broke out in 1921, with whites attacking blacks. In one of the costliest episodes of racial violence in American history, sixteen hours of rioting resulted in 35 city blocks destroyed, $1.8 million in property damage, and a death toll estimated to be as high as 300 people.^[60] By the late 1920s, the Ku Klux Klan had declined to negligible influence within the state.^[61]

During the 1930s, parts of the state began suffering the consequences of poor farming practices, extended drought and high winds. Known as the Dust Bowl, areas of Kansas, Texas, New Mexico and northwestern Oklahoma were hampered by long periods of little rainfall and abnormally high temperatures, sending thousands of farmers into poverty and forcing them to relocate to more fertile areas of the western United States.^[62] Over a twenty-year period ending in 1950, the state saw its only historical decline in population, dropping 6.9 percent as impoverished families migrated out of the state after the Dust Bowl.

Soil and water conservation projects markedly changed practices in the state and led to the construction of massive flood control systems and dams; they built hundreds of reservoirs and man-made lakes to supply water for domestic needs and agricultural irrigation. By the 1960s, Oklahoma had created more than 200 lakes, the most in the nation.^[12][63]

In 1995, Oklahoma City was the site of the worst act of domestic terrorism in American history. The Oklahoma City bombing of April 19, 1995, in which Timothy McVeigh and Terry Nichols detonated an explosive outside of the Alfred P. Murrah Federal Building, killed 168 people, including 19 children. The two men were convicted of the bombing: McVeigh was sentenced to death and executed by the federal government on June 11, 2001; his partner Nichols is serving a sentence of life in prison without the possibility of parole.^[64] McVeigh's army buddy, Michael Fortier, got 12 years in prison and, ultimately, a $75,000 fine for helping sell guns (to raise funds for the bombing) and for helping to examine the Murrah Federal building prior to the terrorist attack. Wife, Lori Fortier (now dead), was granted immunity for testifying.

Economy[link]

The BOK Tower of Tulsa, Oklahoma's second tallest building, serves as the world headquarters for Williams Companies.

Based in the sectors of aviation, energy, transportation equipment, food processing, electronics, and telecommunications, Oklahoma is an important producer of natural gas, aircraft, and food.^[8] The state ranks second in the nation for production of natural gas,^[65] and is the 27th-most agriculturally productive state, ranking 5th in production of wheat.^[66] Four Fortune 500 companies and six Fortune 1000 companies are headquartered in Oklahoma,^[67] and it has been rated one of the most business-friendly states in the nation,^[68] with the 7th-lowest tax burden in 2007.^[69] In 2010, Oklahoma City-based Love's Travel Stops & Country Stores ranked 18th on the Forbe's list of largest private companies, Tulsa-based QuikTrip ranked 37th, and Oklahoma City-based Hobby Lobby ranked 198th in 2010 report.^[70] From 2006 to 2010, Oklahoma's gross domestic product grew from $131.9 billion to $147.5 billion, a jump of 10.6 percent.^[71] Oklahoma's gross domestic product per capita was $35,480 in 2010, which was ranked 40th among the states.^[72] Though oil has historically dominated the state's economy, a collapse in the energy industry during the 1980s led to the loss of nearly 90,000 energy-related jobs between 1980 and 2000, severely damaging the local economy.^[73] Oil accounted for 35 billion dollars in Oklahoma's economy in 2007,^[74] and employment in the state's oil industry was outpaced by five other industries in 2007.^[75] As of August 2011, the state's unemployment rate is 5.6%.^[76]

Industry[link]

In mid 2011, Oklahoma had a civilian labor force of 1.7 million and total non-farm employment fluctuated around 1.5 million.^[75] The government sector provides the most jobs, with 339,300 in 2011, followed by the transportation and utilities sector, providing 279,500 jobs, and the sectors of education, business, and manufacturing, providing 207,800, 177,400, and 132,700 jobs, respectively.^[75] Among the state's largest industries, the aerospace sector generates $11 billion annually.^[68] Tulsa is home to the largest airline maintenance base in the world, which serves as the global maintenance and engineering headquarters for American Airlines.^[77] In total, aerospace accounts for more than 10 percent of Oklahoma's industrial output, and it is one of the top 10 states in aerospace engine manufacturing.^[8] Because of its position in the center of the United States, Oklahoma is also among the top states for logistic centers, and a major contributor to weather-related research.^[68] The state is the top manufacturer of tires in North America and contains one of the fastest-growing biotechnology industries in the nation.^[68] In 2005, international exports from Oklahoma's manufacturing industry totaled $4.3 billion, accounting for 3.6 percent of its economic impact.^[78] Tire manufacturing, meat processing, oil and gas equipment manufacturing, and air conditioner manufacturing are the state's largest manufacturing industries.^[79]

Energy[link]

A major oil producing state, Oklahoma is the fifth-largest producer of crude oil in the United States.^[74]

Oklahoma is the nation's third-largest producer of natural gas, fifth-largest producer of crude oil, and has the second-greatest number of active drilling rigs,^[74][80] and ranks fifth in crude oil reserves.^[81] While the state ranked eighth for installed wind energy capacity in 2011,^[82] it is at the bottom of states in usage of renewable energy, with 94 percent of its electricity being generated by non-renewable sources in 2009, including 25 percent from coal and 46 percent from natural gas.^[83] Ranking 13th for total energy consumption per capita in 2009,^[84] Oklahoma's energy costs were 8th lowest in the nation.^[85] As a whole, the oil energy industry contributes $35 billion to Oklahoma's gross domestic product, and employees of Oklahoma oil-related companies earn an average of twice the state's typical yearly income.^[74] In 2009, the state had 83,700 commercial oil wells churning 65.374 million barrels (10,393,600 m³) of crude oil.^[86] Eight and a half percent of the nation's natural gas supply is held in Oklahoma, with 1.673 trillion cubic feet (47.4 km³) being produced in 2009.^[86]

According to Forbes Magazine, Oklahoma City-based Devon Energy Corporation, Chesapeake Energy Corporation, and SandRidge Energy Corporation are the largest private oil-related companies in the nation,^[87] and all of Oklahoma's Fortune 500 companies are energy-related.^[67] Tulsa's ONEOK and Williams Companies are the state's largest and second-largest companies respectively, also ranking as the nation's second and third-largest companies in the field of energy, according to Fortune Magazine.^[88] The magazine also placed Devon Energy as the second-largest company in the mining and crude oil-producing industry in the nation, while Chesapeake Energy ranks seventh respectively in that sector and Oklahoma Gas & Electric ranks as the 25th-largest gas and electric utility company.^[88]

Agriculture[link]

The 27th-most agriculturally productive state, Oklahoma is fifth in cattle production and fifth in production of wheat.^[66][89] Approximately 5.5 percent of American beef comes from Oklahoma, while the state produces 6.1 percent of American wheat, 4.2 percent of American pig products, and 2.2 percent of dairy products.^[66] The state had 83,500 farms in 2005, collectively producing $4.3 billion in animal products and fewer than one billion dollars in crop output with more than $6.1 billion added to the state's gross domestic product.^[66] Poultry and swine are its second and third-largest agricultural industries.^[89]

Culture[link]

Oklahoma is placed in the South by the United States Census Bureau,^[90] but lies fully or partially in the Southwest, and southern cultural regions by varying definitions, and partially in the Upland South and Great Plains by definitions of abstract geographical-cultural regions.^[91] Oklahomans have a high rate of German, English, Scotch-Irish, and Native American ancestry,^[92] with 25 different native languages spoken.^[13] Because many Native Americans were forced to move to Oklahoma when White settlement in North America increased, Oklahoma has a lot of linguistic diversity. Mary Linn, an associate professor of anthropology at the University of Oklahoma and the associate curator of Native American languages at the Noble Museum, said that Oklahoma also has high levels of language endangerment.^[93]

Six governments have claimed the area now known as Oklahoma at different times,^[94] and 67 Native American tribes are represented in Oklahoma,^[45] including the greatest number of tribal headquarters and 39 federally recognized nations.^[95] Western ranchers, Native American tribes, southern settlers, and eastern oil barons have shaped the state's cultural predisposition, and its largest cities have been named among the most underrated cultural destinations in the United States.^[96][97] While residents of Oklahoma are associated with stereotypical traits of southern hospitality – the Catalogue for Philanthropy ranks Oklahomans 4th in the nation for overall generosity^[98] – the state has also been associated with a negative cultural stereotype first popularized by John Steinbeck's novel "The Grapes of Wrath", which described the plight of uneducated, poverty-stricken Dust Bowl-era farmers deemed "Okies".^{[99][100][101]} However, the term is often used in a positive manner by Oklahomans.^[100]

Arts and theater[link]

Philbrook Museum is one of the top 50 fine art museums in the United States.^[102]

In the state's largest urban areas, pockets of jazz culture flourish,^[103] and Native American, Mexican American, and Asian American communities produce music and art of their respective cultures.^[104] The Oklahoma Mozart Festival in Bartlesville is one of the largest classical music festivals in the southern United States,^[105] and Oklahoma City's Festival of the Arts has been named one of the top fine arts festivals in the nation.^[103]

The state has a rich history in ballet with five Native American ballerinas attaining worldwide fame. These were Yvonne Chouteau, sisters Marjorie and Maria Tallchief, Rosella Hightower and Moscelyne Larkin, known collectively as the Five Moons. The New York Times rates the Tulsa Ballet as one of the top ballet companies in the United States.^[103] The Oklahoma City Ballet and University of Oklahoma's dance program were formed by ballerina Yvonne Chouteau and husband Miguel Terekhov. The University program was founded in 1962 and was the first fully accredited program of its kind in the United States.^{[106][107][108]} In Sand Springs, an outdoor amphitheater called "Discoveryland!" is the official performance headquarters for the musical Oklahoma!^[109] Historically, the state has produced musical styles such as The Tulsa Sound and Western Swing, which was popularized at Cain's Ballroom in Tulsa. The building, known as the "Carnegie Hall of Western Swing",^[110] served as the performance headquarters of Bob Wills and the Texas Playboys during the 1930s.^[111] Stillwater is known as the epicenter of Red Dirt music, the best-known proponent of which is the late Bob Childers.

Prominent theatre companies in Oklahoma include, in the capital city, Oklahoma City Theatre Company, Carpenter Square Theatre, Oklahoma Shakespeare in the Park, and CityRep. CityRep is a professional company affording equity points to those performers and technical theatre professionals. In Tulsa, Oklahoma's oldest resident professional company is American Theatre Company, and Theatre Tulsa is the oldest community theatre company west of the Mississippi. Other companies in Tulsa include Heller Theatre and Tulsa Spotlight Theater. The cities of Norman, Lawton, and Stillwater, among others, also host well-reviewed community theatre companies.

Oklahoma is in the nation's middle percentile in per capita spending on the arts, ranking 17th, and contains more than 300 museums.^[103] The Philbrook Museum of Tulsa is considered one of the top 50 fine art museums in the United States,^[102] and the Sam Noble Oklahoma Museum of Natural History in Norman, one of the largest university-based art and history museums in the country, documents the natural history of the region.^[103] The collections of Thomas Gilcrease are housed in the Gilcrease Museum of Tulsa, which also holds the world's largest, most comprehensive collection of art and artifacts of the American West.^[112] The Egyptian art collection at the Mabee-Gerrer Museum of Art in Shawnee is considered to be the finest Egyptian collection between Chicago, IL and Los Angeles, CA.^[113] The Oklahoma City Museum of Art contains the most comprehensive collection of glass sculptures by artist Dale Chihuly in the world,^[114] and Oklahoma City's National Cowboy and Western Heritage Museum documents the heritage of the American Western frontier.^[103] With remnants of the Holocaust and artifacts relevant to Judaism, the Sherwin Miller Museum of Jewish Art of Tulsa preserves the largest collection of Jewish art in the Southwest United States.^[115]

Festivals and events[link]

Native American cultural events like pow wows are common in Oklahoma.

Oklahoma's centennial celebration was named the top event in the United States for 2007 by the American Bus Association,^[116] and consisted of multiple celebrations saving with the 100th anniversary of statehood on November 16, 2007. Annual ethnic festivals and events take place throughout the state such as Native American powwows and ceremonial events, and include festivals (as examples) in Scottish, Irish, German, Italian, Vietnamese, Chinese, Czech, Jewish, Arab, Mexican and African-American communities depicting cultural heritage or traditions. During a 10-day run in Oklahoma City, the Oklahoma State Fair attracts close to one million people,^[117] and large pow-wows, Asian festivals, and Juneteenth celebrations are held in the city each year. The Tulsa State Fair attracts over one million people during its 10-day run,^[118] and the city's Mayfest festival entertained more than 375,000 people in four days during 2007.^[119] In 2006, Tulsa's Oktoberfest was named one of the top 10 in the world by USA Today and one of the top German food festivals in the nation by Bon Appetit magazine.^[120] Tulsa also hosts the annual music festival Dfest, a festival that highlights native Oklahoma bands and musicians. Norman plays host to the Norman Music Festival. Norman is also host to the Medieval Fair of Norman, which has been held annually since 1976 and was Oklahoma’s first medieval fair.

Law and government[link]

The Oklahoma State Capitol located in Oklahoma City.

Oklahoma is a constitutional republic with a government modeled after the Federal Government of the United States, with executive, legislative, and judicial branches.^[180] The state has 77 counties with jurisdiction over most local government functions within each respective domain,^[20] five congressional districts, and a voting base with a majority in the Democratic Party.^[14] State officials are elected by plurality voting in the state of Oklahoma.

State government[link]

The Legislature of Oklahoma consists of the Senate and the House of Representatives. As the lawmaking branch of the state government, it is responsible for raising and distributing the money necessary to run the government. The Senate has 48 members serving four-year terms, while the House has 101 members with two-year terms. The state has a term limit for its legislature that restricts any one person to a total of twelve cumulative years service between both legislative branches.^[181][182]

Oklahoma's judicial branch consists of the Oklahoma Supreme Court, the Oklahoma Court of Criminal Appeals, and 77 District Courts that each serves one county. The Oklahoma judiciary also contains two independent courts: a Court of Impeachment and the Oklahoma Court on the Judiciary.

The Five congressional districts in Oklahoma.

The executive branch consists of the Governor, their staff, and other elected officials. The principal head of government, the Governor is the chief executive of the Oklahoma executive branch, serving as the ex officio Commander-in-Chief of the Oklahoma National Guard when not called into Federal use and reserving the power to veto bills passed through the Legislature. The responsibilities of the Executive branch include submitting the budget, ensuring that state laws are enforced, and ensuring peace within the state is preserved.^[183]

Local government[link]

The state is divided into 77 counties that govern locally, each headed by a three-member council of elected commissioners, a tax assessor, clerk, court clerk, treasurer, and sheriff.^[184] While each municipality operates as a separate and independent local government with executive, legislative and judicial power, county governments maintain jurisdiction over both incorporated cities and non-incorporated areas within their boundaries, but have executive power but no legislative or judicial power. Both county and municipal governments collect taxes, employ a separate police force, hold elections, and operate emergency response services within their jurisdiction.^[185][186] Other local government units include school districts, technology center districts, community college districts, rural fire departments, rural water districts, and other special use districts.

Thirty-nine Native American tribal governments are based in Oklahoma, each holding limited powers within designated areas. While Indian reservations typical in most of the United States are not present in Oklahoma, tribal governments hold land granted during the Indian Territory era, but with limited jurisdiction and no control over state governing bodies such as municipalities and counties. Tribal governments are recognized by the United States as quasi-sovereign entities with executive, judicial, and legislative powers over tribal members and functions, but are subject to the authority of the United States Congress to revoke or withhold certain powers. The tribal governments are required to submit a constitution and any subsequent amendments to the United States Congress for approval.^[187][188]

National politics[link]

For most of the first half of the 20th century, Oklahoma was a Democratic stronghold. From 1908 to 1948, the state only supported a Republican twice, in 1920 and 1928. However, Oklahoma Democrats have always been considerably more conservative than their counterparts in the rest of the nation, and the state has become increasingly friendly to Republicans at the national level.

Though registered Republicans are a minority in the state,^[14] Oklahoma has voted for a Republican for President in all but one election since 1952. In 2004 and 2008, George W. Bush and John McCain swept every county in the state, both receiving over 65 percent of the statewide vote. In 2008, Oklahoma was the only state whose counties voted unanimously for McCain.^[190]

Generally, Republicans are strongest in Oklahoma City, Tulsa and their close-in suburbs, as well as the Panhandle. Democrats are strongest in the eastern part of the state and Little Dixie.

Following the 2000 census, the Oklahoma delegation to the U.S. House of Representatives was reduced from six to five representatives, each serving one congressional district. For the 112th Congress (2011–2013), there are no changes in party strength, and the delegation has four Republicans and one Democrat. Oklahoma's U.S. senators are Republicans Jim Inhofe and Tom Coburn, and its U.S. Representatives are John Sullivan (R-OK-1), Dan Boren (D-OK-2), Frank D. Lucas (R-OK-3), Tom Cole (R-OK-4), and James Lankford (R-OK-5).

Under Oklahoma law, municipalities are divided into two categories: cities, defined as having more than 1,000 residents, and towns, with under 1,000 residents. Both have legislative, judicial, and public power within their boundaries, but cities can choose between a mayor-council, council-manager, or strong mayor form of government, while towns operate through an elected officer system.^[185]
