The Plains Indians are a group of Native American tribes that historically inhabited the Great Plains region of the United States and Canada. They are known for their nomadic lifestyle, primarily following the herds of bison, which were central to their culture and survival. Tribes such as the Lakota, Cheyenne, and Comanche are among the most recognized Plains Indians. These tribes developed rich cultural traditions, including unique art, music, and spiritual practices. They lived in tipis, which were well-suited for their mobile lifestyle, and engaged in trade with neighboring tribes and European settlers. The Plains Indians played a significant role in the history of North America, particularly during the westward expansion of the United States.
