1. in what year did oklahoma prehistory end and history begin?

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.

Most of Oklahoma was set aside as Indian Territory before the Civil War. It was opened for general settlement around 1890—the "Sooners" were settlers who jumped the gun. Statehood came to the poor ranching and farming state in Oklahoma, but soon oil was discovered and new wealth poured in.

Historians David Baird and Danny Goble have searched for the essence of the historical experiences of the people of Oklahoma. They find that, "The shared experiences of Oklahoma's people over time speak of optimism, innovation, perseverance, entrepreneurialism, common sense, collective courage, and simple decency. Those, not victimization, were the core values."[1]
