In 1953 Jef Rens, assistant director-general of the International Labor Organization (ILO), the UN specialized agency for social and labor affairs, returned to Geneva from an official mission to Egypt. Rens was both fascinated and shocked by the profound changes taking place in the country as a result of the government's efforts to manage what he described as the transition from a traditional rural into a modern industrialized society. In terms of the broader social consequences this transition would inevitably bring about, the future seemed still an open book. This was in Rens's view exactly the point where the ILO came in. “This part of the world and similar areas are moving—that's certain,” he noted enthusiastically in his report, “so let's not miss the chance to help them move the ILO way!”1 Rens's reference to a specific “ILO way” of modernization points very clearly to the major transformation international organizations like the ILO underwent both in terms of self-conception and programmatic profile in the post-World War II era, when they began to address the problems of countries which were soon to be summarized under the heading “third world”. In this context, international organizations served as key transmitters of, as well as major arenas for, debate on ideas and concepts of modernization on a global scale. The UN system in particular played a key role in establishing a development discourse in the period after the World War II. Right from when it was set up in 1945, it was one of the central forums—if not the central forum—in which development issues were discussed and global benchmarks established. Furthermore, in the years following 1945, international organizations served as a pool and transmitter of expert knowledge on development policy, and thus made a significant contribution to ensuring that development thinking continued to evolve and approaches to development policy were realigned as the need arose. Perhaps no other field, then, illustrates the enormous increase in the importance of international organizations in the twentieth century better than that of development policy.2 While this fact is increasingly recognized in historical research, the important role the ILO played in the propagation of the development idea has, unlike in the case of the United Nations or the Bretton Woods institutions, been largely ignored to date.3 One reason for this exclusion is that the ILO, which was founded in 1919 as part of the Paris Peace Treaties, has largely been identified with its activities defining labor standards. Its high reputation as a body which since the end of World War I, has defined and promoted a myriad of so-called international labor standards dealing with a broad range of topics4 may have obscured the fact that, after 1945, the ILO quickly changed from a standard-setting to an operational institution providing technical assistance in economically and socially “underdeveloped areas” of the world—activities that have ever since formed the second pillar on which the organization's work rests.5
