This collection of essays, contributed by his friends, pays tribute to the work of Peter R. Baehr, whose impressive career spans some 40 years of activity devoted to the cause of human rights. Although human rights remains the leitmotiv of Professor Baehr's career, the themes explored in this collection - the role of the nation-state in the 21st century, international organisations and foreign policy - are a reflection of the versatility of his work and the range of his interests. This volume thus offers the reader a stimulating collection of essays by a wide range of international experts on both the theory and the practice of human rights within the context of the nation-state of the 21st century.
