在上个世纪，政府对土著语言的镇压遍布了整个世界，包括美国。1868年，总统Ulysses S. Grant特派了一个联邦委员会试图与美印第安部落达成和平协议。但是，这些部落都为了保护他们的领土而极力反抗。
委员会最终确定这是由于语言差异造成的问题。它表示，所有居住在美国的人都应该使用一样的语言，这样才能有同样的思考方式。委员会指出，美印第安孩子都应该离开家庭带他们去政府开办的寄宿学校，在那里他们只能说英语。
联邦政府于1879年建立了它的第一所为接收美印第安儿童的寄宿学校。在那里的孩子们，一旦说了自己的土著语言将会受到惩罚。50年里，数以千计的土著美国儿童被送到这些学校去生活，工作并接受英语教育。在二十世纪三十年代晚期，许多这样的学校都关闭了。但是他们在美印第安人语言上造成的影响却仍然存在。
