The objective of Scott Pegg's book is to examine the role of the de facto state in the international system. The book begins with a description of quasi-states, entities defined as ineffective states that possess internationally recognized sovereignty as indicated by membership in the United Nations. The de facto state, by contrast, is a political movement that possesses substantial control over a specified territory and population but lacks recognition of its sovereignty by the international community. As expressed by Pegg, “The quasi-state is legitimate no matter how ineffective it is. . . . The de facto state, on the other hand, is a functioning reality that is denied legitimacy by the rest of international society” (p. 5).
