Final answer:
The first schools established by the Five Civilized Tribes and the U.S. government aimed to assimilate Native American children into Euro-American culture by separating them from their tribal cultures and teaching them vocational skills.
Step-by-step explanation:
The boarding schools established for Native American children by the Five Civilized Tribes and the United States government in the late 19th century had the purpose of assimilating Native American children into Euro-American culture. This assimilation was achieved by separating the children from their families and tribes to weaken the transmission of tribal cultures and languages. The curriculum primarily focused on vocational training rather than traditional Indigenous knowledge or professional development, emphasizing skills like farming for boys and domestic science for females. The government-run and mission-run schools sought to reform Native American children into the image of American society, teaching them English, Christianity, and manual labor skills while discouraging traditional practices and languages.
