In the first comprehensive history and assessment of the international propaganda program or the United Nations, Mark D. Alleyne analyses how the UN ran a propaganda project for all its history in the twentieth century but repeatedly denied it had one. He shows how the UN's work to win world public opinion originated in a number of places, including the evolution in the practice of war, advances in social psychology, and the attempt to outlaw the hateful propaganda that marked World War II. This is a work in the constructivist and critical theory traditions of International Relations research, and as such, Alleyne is able to make connection between an array of seemingly unrelated phenomena, including World AIDS Day, Hollywood movies about the UN, and the campaign to free Nelson Mandela.
