Arman Sarvarian's _The Law of State Succession_ provides a comprehensive, practical, and empirical overview of the topic, establishing State succession as a distinct field with a cohesive set of rules. From the secession of the United States of America in 1784 to that of South Sudan in 2011, the book digests and analyses State practice spanning more than two centuries. It is based on research into a wide and diverse range of case studies, including archival and previously unpublished data. Reconstructing the intellectual foundation of the field, the book offers a vision for its progressive development - one that is rooted in an interpretation of State practice that transcends the politics of the codification projects in the decolonization and desovietization eras. The book examines international law on State succession with respect to territorial rights and obligations, State property (including archives) and debt, treaties, international claims and responsibility, as well as nationality and private property (including concessions and investments). Its central focus is identifying the general rules of international law in order to guide States in the negotiation of succession agreements, the interpretation of ambiguous or incomplete provisions, and the regulation of succession in default of specific agreement. A highly relevant work, _The Law of State Succession_ offers governments, judges, legal practitioners, and scholars an authoritative account of the current law. It enables negotiators to identify different legal paths within succession and assists adjudicators in interpreting provisions of succession agreements and regulating questions omitted from such agreements.
