Why was the Indian boarding school created?

They were founded for the assimilation of Indian youth and children.

Explanation:

Indian residential schools were established and began operations in the late 19th and early 20th centuries. These institutions' primary goal was the assimilation of Indian children and their introduction to European and American culture. Attendees of these schools had the opportunity to get acquainted with Euro-American culture and gain a basic education in various fields. Catholic missionaries originally founded the schools, and the United States government-funded the complete project.
