Where Are the Great Plains?
The Great Plains are the part of North America east of the Rocky Mountains and west of the Mississippi River. The American states that are part of this region are Colorado, Kansas, Montana, Nebraska, New Mexico, North Dakota, Oklahoma, South Dakota, Texas, and Wyoming. The land there is flat and includes prairie, steppe and grassland.
Who Are the Plains Indians?
There were many differently-named tribes who lived on the Great Plains when the Europeans came, but they mostly shared a common culture because of living in similar environments. The buffalo (bison) was a major source of food along with other game and cultivated crops. They also gathered wild fruits and vegetables. Nomadic (roaming) tribes lived in large teepees, often painted with religious symbols. Tribes that did not roam often lived in earthen or grass lodges and would grow crops.
Settlers started moving west as soon as the land by the eastern rivers was claimed. Wanting the right to expand into more territory was one of the factors in the American Revolution, including anger at the Proclamation of 1763 that restricted further settlement. Indeed, many veterans of the Revolution received land grants in the west for their service. In the late 1700s to the early 1800s, the West could mean Ohio, Kentucky, Tennessee, and parts of Pennsylvania. As those places filled up, too, and immigrants kept on coming, they eventually spread across the plains and into the heartland.
