Oklahoma occupies a singular place in Native American history. The state’s very name derives from the Choctaw words okla (people) and humma (red), meaning “red people.” For millennia it was home to Indigenous nations such as the Wichita, Caddo, Osage, and Apache peoples, and in the 19th century it became the destination for tens of thousands of Southeastern tribal citizens forcibly removed from their homelands—the process remembered as the Trail of Tears. By 1900, more than 30 tribes had been relocated to what was formally designated Indian Territory, and today 39 federally recognized tribes maintain their headquarters in Oklahoma. The state’s story—embracing the Land Run of 1889, statehood in 1907, the Tulsa Race Massacre of 1921, the Dust Bowl, and the oil boom—is inseparable from the resilience and sovereignty of its Native nations.
Oklahoma’s Original Indigenous Residents
Humans arrived in the region now known as Oklahoma an estimated 30,000 years ago, organizing into agriculture-based settlements roughly 2,000 years ago. Historians and archaeologists trace the Wichita and Caddo peoples back some 2,000 years, while the Osage and Apachean-speaking peoples were present in the region before European contact. By the time Spanish explorers entered the area in the 1500s, the land was also home to the Pawnee and Quapaw. The Kiowa, Comanche, Arapaho, and Cheyenne nations raided and used the western plains, their lives transformed—as they were across the continent—by the arrival of the horse during the era historians describe as the rise of the Horse Nations of the Plains.
The Wichita, Caddo, Apache, and Quapaw are considered the area’s original Indigenous tribes, and their descendants remain integral to Oklahoma’s cultural landscape.

European Exploration and the Struggle for Control
Spanish expeditioners arrived in the 1500s in pursuit of the fabled Seven Cities of Gold. In 1539, Hernando de Soto traveled from Florida through Arkansas and potentially the eastern edge of Oklahoma. In 1541, Francisco Vásquez de Coronado journeyed from New Mexico across Texas and Oklahoma before reaching Kansas; finding no gold, he returned to Mexico. In the early 1700s, French adventurers explored the region and built trading partnerships with the Wichita, Osage, and Pawnee, competing with Spain for influence over eastern Oklahoma. Yet by the beginning of the 1800s, no permanent European settlement existed in the region.
Indian Territory and the Trail of Tears
Oklahoma entered U.S. possession through the Louisiana Purchase of 1803. President Thomas Jefferson envisioned part of the new acquisition as a reservation for Native Americans living east of the Mississippi River, and by 1820 the federal government had designated the area as Indian Territory.
On May 28, 1830, President Andrew Jackson signed the Indian Removal Act, authorizing the government to negotiate removal treaties with tribes east of the Mississippi. The principal nations affected—the Cherokee, Muscogee (Creek), Choctaw, Chickasaw, and Seminole—held roughly 25 million acres of coveted land across Georgia, Tennessee, Alabama, Mississippi, and North Carolina. The tribes resisted through diplomacy and warfare, but the U.S. military removed those who refused to relocate. By 1840, nearly 100,000 Indigenous people had been evicted, and as many as 15,000 died of disease, exposure, and malnutrition on journeys lasting five to six months. Some nations lost up to one-third of their members. The full story of this era—its treaties, its casualties, and the 28-year-long campaign of removal—is examined in depth in our coverage of the Indian Removal Act and the forced removal of the Cherokee and Southeastern nations.
By 1883, Oklahoma contained 25 reservations for 37 tribes—nations that had never before lived side by side, forced into proximity within boundaries drawn by the federal government. The five nations removed from the Southeast, recognized as the “Five Civilized Tribes,” rebuilt constitutional governments, schools, and打印 communities in exile, though scholars note that many of the cultural practices cited in that label—literacy, centralized governance, and Christianity—already existed in their societies before removal.
The Land Runs, Allotment, and the Fight for Sequoyah
Indian Territory was promised to its Native nations in perpetuity, but land runs, auctions, and allotments steadily dismantled it. The Homestead Act, applied to Oklahoma beginning in 1889, promised settlers up to 160 acres of unassigned public land. The Dawes Act of February 8, 1887, established a federal commission that determined which individuals in the Five Tribes qualified for citizenship and land allotments—those excluded lost their land. The Curtis Act of 1898 then weakened and dissolved tribal governments, placing them under federal control.
In March 1889, the first Oklahoma Land Run opened unassigned lands to white settlers racing to claim homesteads. Settlers who crossed the boundary early—illegally—earned the name “sooners,” which became the state’s enduring nickname. Indian Territory shrank to the eastern half of the state, while the western half became Oklahoma Territory.
Desperate to preserve what remained, the Five Tribes submitted a constitution in 1905 proposing a separate Native-governed state named Sequoyah, honoring the Cherokee polymath who created the Cherokee syllabary. Although a large majority of voters supported the petition, Congress refused to consider it. President Theodore Roosevelt insisted the territories enter the Union jointly, and on November 16, 1907, Oklahoma became the 46th state.
Slavery, All-Black Towns, and the Tulsa Race Massacre
The Five Tribes had adopted the institution of slavery, and when they were removed to Indian Territory in the 1830s, they brought enslaved Black people with them—by the Civil War, Black residents constituted more than 14 percent of the territory’s population. Most Indian Territory nations sided with the Confederacy, though free Black “Buffalo Soldiers” served in both armies. After the Battle of Honey Springs on July 17, 1863, a decisive Union victory, the region remained lawless until the war’s end. The Five Nations abolished slavery by treaty in 1866 (the territory’s postwar agreements), and formerly enslaved people known as Freedmen were offered citizenship and land rights within the nations.
In the decades that followed, African Americans founded more than 20 all-Black towns in Oklahoma between 1865 and 1920—more than any other state—and 13 of those towns survive today. But this growing prosperity stirred violent racism. Shortly after statehood, the legislature passed Jim Crow laws mandating segregation, and tensions culminated in the Tulsa Race Massacre of 1921, when hundreds of Black residents were killed and Tulsa’s prosperous Black district, Greenwood, was burned to the ground.
The struggle for civil rights produced two landmark Supreme Court cases: Sipuel v. Board of Regents of the University of Oklahoma (1948) and McLaurin v. Oklahoma State Regents (1950), both of which paved the way for Brown v. Board of Education. Oklahoma schools were desegregated in the early 1960s.
Oil, the Dust Bowl, and the “Okie” Migration
Oil transformed Oklahoma’s economy. Prospecting began in the 1870s, and between 1900 and 1935, Oklahoma produced more oil than any other mid-continent state. The state capitol in Oklahoma City remains the only capitol in the nation with an oil well beneath it—the “Petunia Number One” well, slant-drilled through a flowerbed in 1941, which produced roughly 1.5 million barrels over 43 years. Oil wealth, however, brought tragedy for some Native nations: readers can learn how outsiders targeted the oil-rich Osage in the era of the Osage murders and the theft of Osage oil fortunes.
The 1930s brought catastrophe. Farmers and ranchers had destroyed the native prairie grasses that held the soil, and when severe drought struck in the early 1930s, strong winds lifted the arid, over-farmed earth into choking dust storms. Oklahoma became one of the regions hardest hit by the Depression-era Dust Bowl, powerfully chronicled in John Steinbeck’s The Grapes of Wrath. Between 1930 and 1940, refugees fled westward, mainly to California and Arizona, where locals derisively called them “Okies” regardless of their state of origin. Oklahoma lost a net total of approximately 440,000 residents during the Depression decade.
Historical Context & Key Cultural Takeaways
- Layered sovereignty: Oklahoma was not an empty frontier but a succession of Indigenous homelands—from the ancient Wichita and Caddo to the removed Southeastern nations—compounding one of the largest concentrations of tribal governments in the United States, with 39 tribes headquartered in the state today.
- Removal as defining trauma: Indian Territory was created through the Indian Removal Act of 1830; the Trail of Tears cost somewhere between roughly 4,000 and 15,000 Cherokee lives alone across the removal era, according to estimates, and thousands more from other nations.
- The broken promise: Despite guarantees that Indian Territory would belong to its nations in perpetuity, allotment (Dawes Act, 1887), the Curtis Act (1898), and land runs reduced it by nearly half before statehood dissolved it entirely in 1907.
- Cultural resilience: The defeated Sequoyah statehood movement of 1905 demonstrates that Native nations pursued statehood through constitutional, democratic means—an assertion of political sophistication that Congress simply refused to hear.
- Intertwined histories: Oklahoma’s Black and Native histories are inseparable—through slavery in the Five Tribes, the Freedmen and all-Black towns, and the Tulsa Race Massacre—making the state a unique crossroads of American racial history.
Frequently Asked Questions
What does the name “Oklahoma” mean?
“Oklahoma” comes from Choctaw words meaning “red people”—okla (people) and humma (red). The name was chosen by Choctaw elder Allen Wright and reflects the state’s foundational Indigenous identity.
Which tribes were forced to move to Indian Territory?
The principal nations removed under the Indian Removal Act of 1830 were the Cherokee, Muscogee (Creek), Choctaw, Chickasaw, and Seminole—known historically as the Five Civilized Tribes. By 1900, more than 30 tribes from across the United States had been relocated to Indian Territory.
Why is Oklahoma called the “Sooner State”?
During the Land Run of 1889, settlers who illegally crossed the territory’s border before the official starting hour were called “sooners.” The term became the state’s official nickname after Oklahoma achieved statehood in 1907.
What was the state of Sequoyah?
In 1905, leaders of the Five Civilized Tribes drafted a constitution proposing a Native-governed state named for Sequoyah, the creator of the Cherokee syllabary. Although voters in Indian Territory overwhelmingly approved it, Congress refused to consider the proposal, and Oklahoma and Indian Territory were combined into a single state in 1907.
How did the Dust Bowl affect Oklahoma’s Native and rural communities?
Drought and wind erosion beginning around 1930 destroyed farms across the over-plowed plains. Between 1930 and 1940, Oklahoma lost approximately 440,000 residents to westward migration, and “Okie” became a nationwide term of derision for Dust Bowl migrants from all 19 affected states.
Enduring Legacy: Oklahoma’s Native Nations Today
Oklahoma’s modern identity rests on the endurance of its 39 federally recognized tribes. Nations such as the Cherokee Nation, Choctaw Nation, Chickasaw Nation, Muscogee (Creek) Nation, and Osage Nation operate their own governments, courts, schools, language programs, and museums—reclaiming the sovereignty that allotment and statehood were designed to erase. Institutions like the Oklahoma Historical Society preserve the documentary record of removal, treaty-making, and tribal governance, while events such as the Tulsa Race Massacre centennial have renewed national attention to the state’s difficult history. From the Trail of Tears to the land runs and beyond, Oklahoma remains what its Choctaw name promises: a land defined by its peoples, and by their refusal to disappear.
