This book examines the League of Nations, state-supported terrorism, and British foreign policy after the rise of Hitler in the 1930s. It argues that with strong leadership from Britain and France, the League made it possible for states to preserve the peace of Europe after terrorists aided by Italy and Hungary killed the King of Yugoslavia in 1934. This achievement represents the League at its most effective and demonstrates that the organization could carry out its peacekeeping functions. The League also made it possible to draft two international conventions to suppress and punish acts of terrorism. While both conventions were examples of productive collaboration, in the end, few governments supported the League's anti-terrorism project in itself. Still, for Britain, Geneva served the cause of peace by helping states to settle their differences by mediation and concession while promoting international cooperation, a central conviction of British "appeasement" policy in the 1930s.

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.

This book completes a two-volume history of the impact of the mandates system on Anglo-French colonialism in Africa from 1914 to 1946. This second volume explains how the League of Nations mandates system fused two of the predominant and compelling global forces of the twentieth century: imperialism and Wilsonian internationalism. After the First World War, Britain and France administered most of Germany's former tropical African colonies as 'mandates' under the supervision of the League as 'a sacred trust of civilisation. This system of international trusteeship changed British and French rule in Africa. In short, 'mandates' were not 'colonies'. Mandates meant less militarism, more commercial equality, a greater emphasis on the interests of Africans, and an end to the extension of European national sovereignty over colonized peoples. Accountability to the League also required the British and French to reconsider traditional economic, strategic, and ideological assumptions about their empires. In the process, the sacred trust sowed the seeds of self-doubt about the very purpose and future of European imperialism.The mandates system continued to represent a genuine internationalisation and reformation of colonialism and had long-term economic, political, and cultural consequences for Africans and Europeans within the mandated territories. Despite the Depression, repeated Anglo-French foreign policy failures, growing humiliations for Geneva, and war in Africa and Europe, the principles and practices of international trusteeship proved persistent. Mandates demonstrated the relevance of international law, the importance of the League of Nations, and the impact of Wilsonian principles on international relations and European imperialism.
