Thats similar to the US, wcept we manage these lands through the Interior Dept (I believe) along with "help" from several other agencies. We also have the Indian Nations set at about 45 distinct peoples, (even though the differences between Maliseet, Micmac, and PAssamaquoddy is kinda like the difference between Amish and Mennonite)
Set and I disagree mightily on this but I feel that history supports a more active role by the EUropeans at exterminating the NAtive AMericans, all the way up to the start of the 20th century. The "Indian WArs" were nothing more than attempts at clearing land of the NAtive pewoples for some immediate "national goal", which was usually some special interest.
