This volume offers innovative insights into and approaches to the multiple historical intersections between distinct modalities of internationalism and imperialism during the twentieth century, across a range of contexts. Bringing together scholars from diverse theoretical, methodological and geographical backgrounds, the book explores an array of fundamental actors, institutions and processes that have decisively shaped contemporary history and the present. Among other crucial topics, it considers the expansion in the number and scope of activities of international organizations and its impact on formal and informal imperial polities, as well as the propagation of developmentalist ethos and discourses, relating them to major historical processes such as the growing institutionalization of international scrutiny in the interwar years or, later, the emerging global Cold War.

This volume addresses the ways the 'native labour' question in the Portuguese late colonial empire in Africa became a recurrent topic of international and transnational debate and regulation after the Second World War. As other European colonial empires were tentatively transforming their labour and social policies in the aftermath of the war, the Portuguese Empire in Africa resisted significant changes in this domain, preserving a strict dual labour regime. As a result, a growing number of individuals, networks and institutions abroad engaged with labour and social realities in Portuguese African colonies, giving origin to a series of instances of denunciation of labour-related abuses. Portuguese authorities responded to these initiatives by selectively engaging with international norms, languages and mechanisms. However, as global decolonisation gained momentum, international and transnational events and processes would significantly constrain Portuguese imperial and colonial decision-making procedures, with the aim of retaining the empire. Therefore, the 'native labour' question became in its own right a crucial political and diplomatic element of the broader struggles over the meaning of Portuguese imperial legitimacy. As this volume argues, these historical processes are critical to properly understanding the history of Portuguese late colonialism and its protracted trajectory of decolonisation.
