1 Introduction

This introductory chapter provides an overview of international humanitarian law. During the past decades, international humanitarian law has been subject to a progressive development which culminated in the four 1949 Geneva Conventions, the 1977 Protocols Additional to these Conventions, the 1980 Weapons Convention, the 1993 Chemical Weapons Convention, and the 1998 Rome Statute of the International Criminal Court. While many efforts have been made by states to implement their obligations under international humanitarian law, much work remains to be done at international and national levels. This task poses a challenge to political decision-makers and to their legal and military advisers, many of whom must shoulder this workload in addition to other duties and in spite of the pressure of other priorities. Recent achievements of worldwide co-operation in this field are manifold: The interrelationship between humanitarian law and the protection of human rights in armed conflicts is largely accepted and better understood today than ever before. A progressive development of international criminal law has led to increased jurisprudence on war crimes and crimes against humanity by national courts, international ad hoc tribunals, and finally to the establishment of the International Criminal Court (ICC).
