The creation of the League of Nations Permanent Mandates Commission (PMC) at the close of the First World War, and its successor, the United Nations Trusteeship Council (TC), following the Second, were watersheds in the history of modern imperialism. For the first time, the international community had asserted that the well-being of colonial peoples was not merely the private concern of metropolitan states, but a shared responsibility of humankind that transcended national boundaries. Editors R.M. Douglas, Michael D. Callahan, and Elizabeth Bishop have assembled a wide array of scholars to assess the relative weight to be placed on international influence in the process of decolonization. Imperialism on Trial reveals, across a broad cross-section of geographical and political settings, the operation of the complicated and often conflicted dynamic between the national and international dimensions of colonialism in its final and most historically consequential phase.
