Presenting the positive international legal framework concerning the regulation of governmental status, the book engages extensively with historical and contemporary examples, such as the rival governments of Cambodia (1970-75; 1979-89, 1997-98); the recognition of the Taliban (1996-2001; and again beginning in 2021); and the contested identity of Venezuela's president (beginning in 2019). Given the pre-eminence of states in international law and the importance of governments to the representation of states, the systematic examination of practice grounded in solid conceptual foundations renders this book a useful reference point for scholars and practitioners in all fields of international law and beyond.
