"This volume contains a selection of the contributions to an international conference held on 13-15 July 2011 at the University of Pretoria, South Africa. The conference was devoted to the legacy of Dag Hammarskjöld and the continued relevance of the principles he advocated. His term as the Secretary-General of the United Nations occurred when "the wind of change" was blowing across the African continent, and his approach to global justice, peace and security is widely viewed as exemplary. The scholars, officials and political office-bearers that have contributed to this volume examine in historical perspective the values and norms Dag Hammarskjöld lived -- and died -- for. They go on to relate them to the current regional, continental and global policy challenges faced by both the United Nations and regional African organisations in terms of conflict mediation, the rule of law and international collective responsibility."--Provided by publisher.
