Although the Lakota were historically a nomadic people living in tipis, and their Plains Native American culture was based strongly upon buffalo and horse culture, they were expected to farm and raise livestock. With the goal of assimilation, in the late 19th and early 20th centuries, they were forced to send their children to boarding schools; the schools taught English and Christianity, as well as American cultural practices. Generally, they forbade inclusion of Native American traditional culture and language. The children were beaten if they tried to do anything related to their native culture.
