History

Prior to the area being discovered by Europeans, Oklahoma was occupied by a civilization noted for building mounds of earth across the landscape. The most notable archaeological evidence of this are the Spiro Mounds, located in eastern Oklahoma, which yielded artifacts dating between 850 and 1450 AD. It is unknown if the Spiro peoples had any interaction with the European explorers, beginning with Coronado's expedition in 1541. Spanish explorers would continue to explore the area for the fabled Seven Cities of Cibola until they were challenged by the French in the late seventeenth century. In 1803, the territory that would become Oklahoma was sold by the United States as part of the Louisiana Purchase.

Around 1820, the federal government started using Oklahoma as a destination for Native American tribes being relocated from the east coast. Known as Indian Territory, the area became the new home of more than sixty tribes. The largest groups to be resettled were the Five Civilized Tribes (Cherokee, Choctaw, Chickasaw, Creek, and Seminole). Although some of the tribes signed removal treaties, the voluntary nature of them made the relocation a slow process. In 1830, the Indian Removal Act was passed, which granted the federal government greater authority to forcibly remove the tribes to their new territory. Exposed to disease, lack of supplies, and military pressure, there was great suffering among the tribes during their removal and their ordeal is referred to as the Trail of Tears.

The outbreak of the Civil War in 1861, federal troops abandoned Indian Territory and it was coveted by the Confederacy to bolster their food supply. The Five Civilized Tribes agreed to sign Confederate treaties, although some Indians refused to adhere to them, leading to factional conflicts. By mid-1862, the Union had moved into Indian Territory and the Confederates surrendered in June, 1865.

Oklahoma achieved statehood in 1907.
