When the European settlers move west, they come into contact with the Indians of the Great Plains. The most known are the Apache, Cheyenne, Comanche, Otoe, Osage and Omaha Indians. Many stereotypes seen in western movies about the American Indians originate from these tribes. For example, the war bonnets or feathered headdresses traditionally worn by male leaders. But also, the tipi, a conical tent with smoke flaps at the top. And the ceremonial smoking or piece pipe the Indians use to seal a treaty. Many of these traditions can be seen in the beautiful paintings by Karl Bodmer and George Catlin.
