be simply that a people is a group of individuals who unanimously choose a separate state. If the "people" are unanimous in their desire for self-determination, it strengthens their claim. For example, the populations of federal units of the Yugoslav federation were considered a people in the breakup of Yugoslavia, although some of those units had very diverse populations. Another example are the Macedonians in Macedonia. Bulgaria and Greece are now arguing against the Macedonians’ right to self determination under international law. Many of the Macedonians who live in the region have ancestors that date thousands of years and they have the right to identify as Macedonians. Although there is no fully accepted definition of peoples, references are often made to a definition proposed by UN Special Rapporteur Martínez Cobo in his study on discrimination against indigenous populations. UN Independent Expert on the Promotion of a democratic and equitable International Order, Alfred de Zayas, relied on the "Kirby definition" in his 2014 Report to the General Assembly A/69/272 as "a group of persons with a common historical tradition, racial or ethnic identity, cultural homogeneity, linguistic unity, religious or ideological affinity, territorial connection, or common economic life. To this should be added a subjective element: the will to be identified as a people and the consciousness of being a people." Abulof suggests that self-determination entails the "moral double helix" of duality (personal right to align with a people, and the people's right to determine their politics) and mutuality (the right is as much the other's as the self's). Thus, self-determination grants individuals the right to form "a people," which then has the right to establish an independent state, as long as they grant the same to all other individuals and peoples. Criteria for the definition of "people having the right of self-determination" was proposed during 2010 Kosovo case decision of the International Court of Justice: 1. traditions and culture 2. ethnicity 3. historical ties and heritage 4. language 5. religion 6. sense of identity or kinship 7. the will to constitute a people 8. common suffering. Self-determination versus territorial integrity National self-determination appears to challenge the principle of territorial integrity (or sovereignty) of states as it is the will of the people that makes a state legitimate. This implies a people should be free to choose their own state and its territorial boundaries. However, there are far more self-identified nations than
