History

The area that comprises modern day Oklahoma was first brought into the United States as part of the Louisiana Purchase in 1803. The government named it Indian Territory and used it to relocate the Five Civilized Tribes in the 1820's. These relocations were hard on the Indians, with the most famous being the hardships of the Cherokee on the Trail of Tears.
