Native people are in a sense segregated to indian reserves, although we chose whether we want to live there or not, but a reserve gave us a claim to the land and land base; african americans were segregated from the white community; native people (in Canada) were not allowed to vote until the 1960s;
From what I've read in this link:
http://www.123helpme.com/view.asp?id=122370, African Americans were pressured not to participate in the voting process; they did not have equal rights when it came to employment and education; the link discusses an African individual who qualified to attend a university in MIssissippi, but the Governor of Mississippi banned him from registering. Native peoples (in Canada) were not allowed to attend college or university in those days.
