Read the following article and answer the question.

I like William N. Grigg more every time he posts a new essay . During the frontier period , when the government that afflicts us was still in its pupal stage and ( therefore ) most of North America remained relatively free , Washington employed an interesting method of stealing land from various Indian communities . Indian nations such as the Nez Perce , who were organized in fiercely independent bands , posed something of a challenge to Washington , since there was no central oligarchy that could be seduced or intimidated into betraying the entire tribe . So the Feds had to take an incremental approach , negotiating separate treaties that pilfered property tract by tract until the targeted Indian tribe was left with a pitiful , resource - poor and indefensible territory .

What may happen during the times of creating treaties with native americans ?
Their land was slowly stolen by the federal government .
