History of Oklahoma

The history of Oklahoma refers to the history of the state of Oklahoma and the land that the state now occupies. Areas of Oklahoma east of its panhandle were acquired in the Louisiana Purchase of 1803, while the Panhandle was not acquired until the U.S. land acquisitions following the Mexican–American War (1846–1848). Most of Oklahoma was set aside as Indian Territory, with the general borders of the Indian Territory being formed in 1834 from the Indian Intercourse Act.
