Humanity internationalized: cases, dynamics, and comparisons (1945-1980) (HINT) is an international project that will scrutinize the ways in which humanitarian and human rights arguments, norms and policies became an institutionalized topic of international affairs, connected to decolonization. This will be done in different chronologies and in relation to distinct colonial and post-colonial geographies and trajectories, considering diverse international institutions (governmental and non-governmental). HINT is based on multiple archives, and is comparative in nature. It will encourage international scientific cooperation, while enhancing the knowledge and competencies of the national scientific system. HINT engages with two of the most important ongoing scholarly debates in international historiography. First, the one about the historical connections between imperial and colonial dynamics, and their markers of coercion, discrimination and inequality, and the internationalization and institutionalization of humanitarian and human rights regimes. Second, the one about the interdependence between the histories of international organizations and of European late colonialism and decolonization. HINT will do so by assessing, in a comparative way, the various dynamics of internationalization of particular events and processes taking place in colonial contexts that shaped the emergence and historical evolution of humanitarian and human rights regimes – distinct but entangled phenomena –, evaluating as well some related post-colonial manifestations. These processes of internationalization were frequently anticolonial in nature, but they also entailed projects of imperial resilience, both sides being duly analyzed by the project. HINT will be empirically and analytically anchored in specific cases that became the object of systematic interest in international organizations. It will tackle how colonial dynamics shaped the mechanisms and norms of inter-governmental organizations related to human rights and humanitarianism, but it will also include fundamental non-governmental actors such as the International Planned Parenthood Federation or Amnesty International, to mention just two of those that will be studied. It will analyze how events and processes involving the ‘Global South’ were received in those organizations, acknowledging their different role and their unequal ability to intervene. HINT will additionally explore how the legal, socio-economic, political, military and relief instruments deployed by international organizations were received in, and shaped by, local contexts. Also important will be the study of the ways in which the European integration process, another channel of internationalization of colonial issues and humanitarian and human rights arguments, intersected with the trajectories of decolonization. HINT will investigate all these historical and historiographical questions through five distinct, but interconnected, work packages (WP), each related to a broader theme.
