The very purpose of international law is the peaceful settlement of international disputes. Over centuries, states and more recently, organizations have created substantive rules and principles, as well as affiliated procedures, in the pursuit of the peaceful settlement of disputes. This volume of the Library of Essays in International Law focuses on the classic procedures of peaceful settlement: negotiation, good offices, inquiry, conciliation, arbitration, judicial settlement, and agencies for dispute resolution. The introduction provides a unique historic overview, explaining how the procedures first developed and changed over time. Each chapter features a seminal essay that helped create the changes described in the introduction. Being at the center of international law, dispute resolution has always been a core topic of international scholarship, this volume brings together for the first time, the pivotal writing in the field.
