This book is a concise and accessible introduction to the problem of war crimes in modern history, emphasizing the development of laws aimed at regulating the conduct of armed conflict developed from the 19th century to the present.

Bringing together multiple strands of recent research in history, political science, and law, the book starts with an overview of the attempts across the pre-modern world to regulate the initiation, conduct, and outcomes of war. It then presents a survey of the legal revolution of the 19th century when, amidst a global welter of colonial wars, the first body of formal codes and laws relating to distinguishing legal from criminal conduct in war was developed. Further chapters investigate failed but influential attempts to develop the laws of war in the post-World War I period and summarize the major landmarks in international law related to war crimes, such as the Hague conventions and the Nuremberg and Tokyo trials, as well as hundreds of lesser-known post-World War II trials in Europe and Asia. It also looks at the origins and debated significance of the Genocide Convention of 1948 and the 1949 Geneva Conventions, accounts for the acceleration worldwide of war crimes investigations and trials from the 1970s into the 2000s, and summarizes current thinking about international law and the rapidly changing nature of warfare worldwide as well as the memorialization of war crimes.

Including images, documents, a bibliography highlighting the most recent scholarship, a chronology, who's who, and a glossary, this is the perfect introduction for those wishing to understand the complex field or war crimes history and its politics.
