This fully revised fourth edition of Constraints on the Waging of War considers the development of the principal rules of international humanitarian law from their origins to the present day. Of particular focus are the rules governing weapons and the legal instruments through which respect for the law can be enforced. Combining theory and actual practice, this book appeals to specialists as well as to students turning to the subject for the first time.

Who is accountable under international law for the acts committed by armed opposition groups? In today's world the majority of political conflicts involve non-state actors attempting to exert political influence (such as overthrowing a government or bringing about secession). Notwithstanding their impact on the course of events, however, we often know little about these groups, and even less about how to treat their actions legally. In this award-winning scholarship, Liesbeth Zegveld examines the need to legally identify the parties involved when internal conflicts arise, and the reality of their demands for rights. Her study draws upon international humanitarian law, human rights law and international criminal law to consider a fundamental question: who is accountable for the acts committed by non-state actors, or for the failure to prevent or repress these acts? This study will be of interest to academics, postgraduate students and professionals involved with armed conflict and international relations.

Armed opposition groups generally fight governments, seeking overthrow and/or secession. But who is accountable under international law for the acts committed by these groups, or for the failure to prevent these acts? Zegveld examines the need legally to identify the parties involved when armed internal conflict arises, and the reality of their demand for rights. Although currently most armed conflicts are internal, they remain largely uncharted territory in law. This award-winning study will be of interest to academics, postgraduate students and professionals involved with armed conflict and international relations.
