Abstract: The paper begins with a brief discussion of the emergence of specifically Indigenous rights, the significance of self-determination as a means of improving the economic and social conditions of communities, and the problem such rights pose for late 20th versions of egalitarian liberalism. It then examines the liberal culturalist argument for minority rights developed by Will Kymlicka, before turning to James Tully’s elaboration of the historical approach to the justification of Indigenous rights that draws on the tradition of treaty relations in North American colonialism. Finally, it outlines a third approach based on the political liberalism of John Rawls.
