The Sioux Tribe is a group of Native American tribes that primarily inhabit the Great Plains region of the United States. They are divided into three major divisions: the Dakota, Lakota, and Nakota. Historically, the Sioux were known for their nomadic lifestyle, following buffalo herds and living in tipis. The Sioux played a significant role in American history, particularly during the 19th century. They are well-known for their resistance against U.S. government policies, including the Battle of Little Bighorn in 1876. Today, many Sioux people continue to preserve their cultural heritage and traditions while living on reservations.
