taking away the power of the IP
in 1880 the US gov set up special councils among the tribes - these were to take over the chiefs power - threats and bribes were used
1883 special courts took over the chiefs power to judge and punish the IP
in 1885 these courts were abolished in favour of the US federal law
why did the gov make these changes - to assimilate the tribes
impact of legal changes - chiefs had no power
