Unrecognized states are places that do not exist in international politics; they are state-like entities that have achieved de facto independence, but have failed to gain widespread international recognition. Since the Cold-War, unrecognized states have been involved in conflicts over sovereign statehood in the Balkans, the former Soviet Union, South Asia, the Horn of Africa, and the South Pacific; some of which elicited major international crises and intervention, including the use of armed force. Yet they remain subject to many myths and simplifications. Drawing on a number of contemporary and historical cases, from Nagorno Karabakh and Somaliland to Taiwan, this timely new book provides a comprehensive analysis of unrecognized states. It examines their origins, the factors that enable them to survive and explores their likely future trajectories. But it is not just a book about unrecognized states; it is a book about sovereignty and statehood; one which does not shy way from addressing crucial issues such as how these anomalies survive in a system of sovereign states and how the context of non-recognition affects their attempts to build effective state-like entities. Ideal for students and scholars of global politics, peace and conflict studies, Unrecognized States offers a much needed and engaging account of the development of unrecognized states in the modern international system.
