IPresisted going onto reservation for as long as possible - as long as their was buffalo to hunt
treaties gave IPright's to hugehuntingarea'soutside their reservations
once the buffalo was gone, the clause in the treaty that gave the Ip the right to huntoutside their reservation was gone - without their mainfoodsource, the IP needed to learn how to farm and assimilate
the IP had to rely on food from the government to survive after the buffalo was gone
the government could force them to do anything by not sending them food - this got the IP to comply with what ever they wanted
the extinction of the plains opened the plains up for cattleranching - cattleranchers had powerfulfriends in the government
