What did the indian peace commission propose in 1867 behalf of congress?

 To establish peace with certain hostile Indian tribes."

Explanation:

The Indian Peace Comission in 1867 brought together a group of people appointed by the United States Congress in order to reach peace agreements with native communities that were considered "hostile."

The idea and objective were to move the members of native communities to special places called "Reserves". At that time it was considered necessary to "civilize" these tribes, a proposal that is currently widely questioned.

In addition, the United States government had assimilation policies that wanted many communities leave behind native culture and adopt European customs. The peace commission was trying to implement actions that would help with this purpose. One of the main measures and challenges was to promote the change from a nomadic lifestyle to a sedentary lifestyle to develop agriculture.
