This is the first book to provide a thorough international legal account of the European micro-states. Jorri Duursma examines notions of self-determination and statehood in the context of international law, and provides solutions for problems of secession. Drawing on many unpublished documents, she tackles the important questions of what constitutes a people with a right to self-determination, and who is allowed to secede from a state, developing a novel approach to statehood and fragmentation.
