This book has emerged out of the author's experience as Director of an innovative peacemaking, peacekeeping and humanitarian initiative, the International Conference on the Former Yugoslavia, between 1992 and 1996. What was striking about this conference was the experiment of two full-time Co-Chairmen, one from the United Nations and one from the European Union, who laboured tirelessly for peace in different parts of the former Yugoslavia for three and a half years. The strategies and organization of the conference had to be pieced together from the start by the Co-Chairmen and their colleagues; only in retrospect could the question whether there might have been experiences of international peace conferences that might have been useful at the beginning of this process be reviewed. This research is contained in Part One of this book, which offers a review of the role of international peace conferences in history. Part Two contains a case study of the strategies and experiences of the International Conference on the Former Yugoslavia.
