This book offers an insight into the historical, institutional, and topical development of the EU policy in the areas of justice, home affairs, and security, which are all well-embedded in a broader international context. The main part of the book, dedicated to the EU, is preceded by a part on relevant cooperation on the Benelux and Schengen levels. This is followed by a section on cooperation in the areas concerned with Council of Europe, NATO, OSCE, G8, OECD, and UN levels. Without a proper understanding of those cooperation levels, the development and functioning of the EU would be hard to fully grasp. Before addressing the actual policy dimension, all sections start with a historical introduction and a sketch of institutional structures and functioning. For students and professionals in criminology, law, and political science, and every one interested in European and international criminal policy making, this book will prove relevant and insightful.
