Oklahoma
Oklahoma has only been a state for a little over a century, but its history is much longer. Arrow heads from the Clovis culture, Native Americans who traveled through Oklahoma, have been found near the city Anadarko. These arrow heads are about 11,000 years old. The Spiro Mound Building Indians were the state's first permanent settlers. In 1541 the Spanish explorer Coranado traveled through Oklahoma while in search of the Lost City of Gold. During the 1830s, the Five Civilized Tribes were forced to move from the southeastern United States to Indian Territory (now Oklahoma) on the Trail of Tears.
