Indigenous rights are those rights that exist in recognition of the specific condition of the Indigenous peoples. This includes not only the most basic human rights of physical survival and integrity, but also the rights over their land, language, religion, and other elements of cultural heritage that are a part of their existence and identity as a people. This can be used as an expression for advocacy of social organizations, or form a part of the national law in establishing the relation between a government and the right of self-determination among its Indigenous people, or in international law as a protection against violation of Indigenous rights by actions of governments or groups of private interests.
