At a time of profound transformations in international relations, the second edition of Historical Dictionary of the United Nations maps out the continuing and deepening role and relevance of the United Nations in the maintenance of peace and the promotion of development and human rights. Focusing on the past two decades developments, this book contributes to a reasoned and fuller understanding of an organization which remains the cornerstone of a changing world fraught with challenges which simply cannot be addressed either unilaterally or bilaterally. This second edition of Historical Dictionary of the United Nations contains a chronology, an introduction, appendixes, and an extensive bibliography. The dictionary section has over 1,000 cross-referenced entries on its basic organizations, subsidiary bodies, related specialized and other agencies, and nongovernmental actors as well as outstanding figures in its history. This book is an excellent resource for students, researchers, and anyone wanting to know more about the United Nations.
