Can two or more self-differentiating culture-groups coexist within a single political structure? The question may well seem clearly settled by the overwhelming factual evidence of contemporary international politics, for it is indeed a truism that political and ethnic borders seldom coincide. Thus, the very existence of a host of multinational states, including such a time-tested example as the Soviet Union, would appear to document an affirmative answer. On the other hand, a recent spate of political unrest within such geographically diverse and historically unrelated states as, inter aliay Canada, Guyana, India, Uganda, Belgium, the Sudan, Burma, Yugoslavia, Cyprus, Rwanda, the United Kingdom, and Iraq, focuses attention on the common root cause of intrastate yet international conflict and again brings into question the assumptions of the multinational state.
