    “The prohibition of the trafficking..” presentation structure, 2025
    Panel debate, International Congress: Crime, Surveillance and Mobilities in the Atlantic, 19th and 20th centuries, 2025

    Summary

    The phenomenon of transatlantic mobility, as designed by the Portuguese empire, has been shown to encompass both human trafficking and forced labour. The analysis of an evolving population of labourers migrating from Asia to Africa, specifically India and China, facilitates an investigation beyond the confines of Portuguese colonial public works. These labourers constitute a foundational layer of other implications associated with work conditions, incorporating commercial, cultural and legal dimensions. The term “coolie” configures a designation applied to Indian workers mobilised to perform labour in the colonial possessions. Initially, that labour force was allocated to plantations; however, due to labour shortages, it did also encompass a wide range of tasks outside of rural contexts. This assertion may be extended to the concept of origins, as the designation in question was also applied to Chinese-origin workers.

    The expansion and deepening of the historiographical debate surrounding the transnational movement of people and the surveillance of international crime in the Atlantic axis must include the Asian contingents trafficked as labour workforce to Africa and South America. In the context of Portuguese colonial public works, the Benguela Railway – Angola’s largest railway – required a significant workforce of people from diverse backgrounds working in a range of skilled trades. As the African workforce was not proving sufficient for the development of the Portuguese public works overseas, Asian workers were also recruited into the colonial project. Furthermore, this workforce provides an invaluable opportunity to explore the concepts of crime, surveillance and mobilities, which consisted of servitude and oppression, whether in the context of plantations – where this movement originally began – or public works due to labour workforce shortages. The decay of slavery and the continuing demand for goods, it became crucial to determine how to monetise the abolitionist movement. Irrespective of the nuances of this free labour, which bore a striking resemblance to enslaved work, apprenticeships and indentured labour emerged as prominent forms of employment. Transversing multiple thematic axes, this proposal explores transnational criminal behaviour of human trafficking and its entanglement in national, imperial and international control and surveillance on migration and mobility, as well as the internationalization of political, technical and public debates around the criminal question.

    Summary

    Before Mozambique declared independence, the Zambezi Valley was transformed into a vast construction site. Around 3,000 homes and collective facilities were being built to house the populations of the Tauara and Tonga ethnic groups. The decision to build the Cabora Bassa dam in Tete province had a profound impact on the landscape. The project was part of a wider counter-insurgency program designed to reinforce Portugal’s geopolitical importance as a colonial power, with the aim of halting the Mozambican struggle for independence (Pereira, 2022). The Zambezi Planning Office began the ambitious “Changara-Chioco Rural Planning Plan”.

    Based on archival material and photographic reports taken between 1971 and 1973 that recorded the “compulsive” gathering of communities to build these strategic villages, the presentation analyzes the settlement process with the aim of finding (small) signs of resistance that have remained “hidden”. The themes recorded by the military and civil authorities in the area ranged from experimental agricultural fields, health care, “social promotion” activities, water supply and buildings. We are particularly interested in the persistence of ways of living, house plans and construction systems that reproduced pre-colonial processes, as a way of assessing how African vernacular architecture embodied a “silent resistance”.

    Summary

    In 1968, the Governor-general António de Spínola inaugurated a new phase of the war to ensure the Portuguese rule in Guinea-Bissau. Together with canonical military operations, Spínola’s strategy comprised a vast campaign of “development” programs. This plan, promoted under the slogan “A Better Guinea” (“Uma Guiné Melhor”), comprised the construction of new infrastructures (roads, bridges and wells) and the establishment of new villages in rural areas aimed at regrouping disperse population living in strategic war zones. In five years, the Portuguese army managed to build approximately 60 villages, 11880 houses, 196 schools and 51 sanitary posts. This construction effort was aided by the Engineering Battalion 447 (BEng447) based in Bissau. The BEng447 supervised the opening of new roads, wells and bridges; it coordinated the construction sites of new houses and collective services; it supplied building materials on the ground and it provided skilled labour and basic know-how to construction sites. 

    This article seeks to study the military reordering of Guinea-Bissau rural areas and the strategic villages program (1968-1974) through the lens of material, labour and construction sites, answering the following questions: who built the strategic villages in Guinea-Bissau and the collateral war infrastructure? How did the army organise the construction sites and the labour division? Where did the building materials (zinc sheets, palm poles and adobe bricks) come from? And how did BEng447 supply them on site? What was the human and environmental impact of these military operations?  

    The analysis of materials, labour and construction sites management undertaken under Spínola’s government during the war to implement the vast programme of rural reordering and population control, enables a multifaceted understanding of the last stage of war strategy in Guinea-Bissau, revealing the collateral impact of colonial wars, both in the natural and human environment, which constitutes an overlooked subject of studies.

    Summary

    In 2000, in Cidade Velha, Cape Verde, the Portuguese architect Álvaro Siza was queried by an immigrant who was building his house regarding the design of the roof: “It is not good here, the straw. If it catches fire, this whole part will burn. It would be better to let me use tiles”. The episode illustrates the clash between the people’s expectations and the architects’ wishes. In another house, also thatched according to local tradition, the occupant complained about the difficulty of finding materials: “I have fought many wars and I did not accept the thatch”. She wanted a tiled roof, associated with economy, low maintenance and cosmopolitanism. Approximately 35 years prior, during the period of Portuguese colonial rule in Africa, the fishing communities on the island of Luanda, Angola, faced a similar challenge when presented with a proposal for new housing made by the Administrative Commission of the Popular Neighbourhood Fund. Whilst answering the question in the title of this paper, these dwellers indicated to the colonial authorities their preference for fiber-cement roofs, as opposed to the traditional coconut leaf thatch proposed by the architects’ team (Carvalho and Cunha, 1963). 

    The construction of self-built housing units has been accompanied by conflicts between residents and technicians in former colonized countries since the late period of Portuguese colonialism. These conflicts reflect a process of combining multiple construction techniques with different cultural and ethnic origins that affect self-built landscapes. This phenomenon was initially documented by colonial bureaucrats and officials in the 1960s (Redinha, 1964). In response to the colonial government’s decision to support self-built housing as a strategy to address the local population’s lodging shortage, debates about the potential of combining vernacular and industrialized techniques began to emerge within the architectural culture. During modern colonization, various Western design proposals were thus put forth to integrate solutions perceived by the Colonial Public Works’ experts to be expressions of local culture. These proposals assumed that the inherited knowledge of the labor force could be used to facilitate this integration. 

    This paper examines the application of the concept of “community development” in the context of the construction of single-family homes in former Portuguese colonial territories in Africa during the Cold War era (Jerónimo, 2024) to gain insight into the strategies of self-production housing employed by the Portuguese authorities. It crosses the “omnicompetence” of pre-colonial societies (Adamson, 2020), as a latent civilizational dynamic, with a “new vernacular” construction, sponsored by industrialization, via the lens of “creole technologies” (Edgerton, 2007). The aim is to trace a narrative of the colonial building sites of these residential landscapes through three processes of (alleged) optimization: how technicians described the core tasks of domestic-scale works, identifying local agents with the “right skills”; how they tested the receptivity and capacity for self-production of housing through demonstrations (such as model houses); how they managed the interplay between local labor, traditional techniques and industrialized materials to achieve a greater number of units. Finally, the paper questions how the building sites’ dynamics impacted project design.

    Summary

    In 1984, Anthony King suggested that a certain type of house, the bungalow, was spread across different continents by colonial empires shaping a global culture of dwelling from Britain to India, from Africa to Australia. In the African context, in the first half of the 20th century, the bungalow was mobilized by colonial administrations to steer urbanization processes, responding to the demands of cost economy and construction efficiency. This simple type of house, a detached home raised off the ground with a veranda, provided an effective tool for settling the indigenous population, mostly nuclear family and workers, in the cities according to Western expectations of hygiene standard and the need for inhabitant control. At different stages of the imperial project, the bungalow served the colonial agenda of the “civilizing mission”, the “assimilation policy” and the “socio-economic development” of the indigenous population. Within this framework and based on King’s assumption that the bungalow constituted a ‘tool of empire’, often attributed to colonial and western imagery, this paper seeks to prove whether it also represented a site of cosmopolitanism: a contested site of (colonial and modern) universalism. To this end, this paper aims to collect and discuss case studies in which the bungalow has failed as a global colonial home, in detriment to a cosmopolitan, hybrid and multicultural dimension. Examining the inhabitants’ appropriation of housing projects for the indigenous population promoted by the colonial state in Guinea-Bissau, Angola and Mozambique in the last decades of the Portuguese rule, this paper raises the following line of questions: how did the bungalow at last fail as a global colonial home? Can evidence of resistance and contestation by the inhabitants be found hidden in the colonial archives? How did indigenous customs occur within the colonial constraints of order and control? Did the universal and global home allow for a cosmopolitan version of it? How did the bungalow promote hybrid dwelling forms and practices under colonial rule? By analyzing archival material (e.g., administrative accounts, photographic surveys, study mission reports undertaken during the colonial period) and exploring specific case studies, from rural resettlement program carried out during the liberation wars to the first urban neighborhoods for the African population, this paper aims to reveal evidence of resistance and contestation of the bungalow as a “tool of empire”. Engaging and discussing the notion of global and universal versus cosmopolitan and hybrid, this paper unearths counter-histories of the bungalow as a global colonial home in order to contribute to King’s research about dwelling forms, cultures, and global exchanges.

    Summary

    The construction of mining camps in late colonial Central Africa, specifically in Lunda (Angola) and the Copperbelt (encompassing parts of Zambia and the Democratic Republic of Congo), presents a complex narrative that questions the multifaceted roles of laborers within these colonial enterprises. This paper examines the conditions, contributions, and agency of workers engaged in the construction of housing and infrastructure under the rule of the Belgian Union Minière du Haut- Katanga (UMHK) and the Portuguese Companhia de Diamantes de Angola (Diamang), between the 1920s and 1970s, revealing a critical dimension of colonial exploitation, social dynamics, and resistance from the building site.

    Workers and families in Lunda and the Copperbelt were pivotal to the construction of mining camps, yet their contributions are frequently overshadowed by the broader narrative of colonial expertise and development. Despite challenging conditions, laborers demonstrated significant skill in their construction efforts. Traditional artisans, with expertise in masonry, carpentry, and other crafts, played a crucial role alongside large groups of still “invisible” men and women. They were often tasked with building their own housing, using a combination of traditional construction techniques and new methods introduced through colonial influence. This self-construction not only mitigated the inadequate housing provided by the companies but also reflected – to some extent – the laborers’ adaptation to new materials such as brick, corrugated iron sheets, and imported cement. The use of local materials like mud, straw, and wood, along with the incorporation of European architectural elements, led to the emergence of hybrid forms of housing that were both practical and culturally significant.

    Against this common corporate backdrop – shaped by strong cross-border and inter-imperial relations between UMHK and Diamang –, this paper questions the similarities and differences between mining camps, laborers, and building sites in Elizabethville (now Lubumbashi) and those in Lunda. These sites had different conditions and environments influenced by varying colonial administrations, mining company policies, and local contexts. While Elizabethville developed into a significant urban center, with diverse socio-cultural influences and a mix of populations from various regions, the Lunda region was arguably shaped by more dispersed and rural mining settlements. How were housing, construction methods, and technologies affected by these circumstances? What did the building site (un)cover about authorship and knowledge transfer? Were the construction yards places for the formation of cosmopolitan communities?

    Summary

    The spatial dimension of colonialism is a topic frequently addressed by architectural historians, who examine the finished buildings as evidence of the historical processes at work. However, the construction sites themselves were the setting for significant interactions between people, skills, materials, and technologies. Despite the ephemeral nature of these spaces, they exhibited a significant cosmopolitan dimension that has yet to be fully elucidated. What were the dynamics of interaction between laborers from disparate backgrounds and with different agendas? What construction skills and technologies were considered in the process? What was the impact of these interactions on the relationship between tradition, cosmopolitanism, and colonialism?

    This session on Colonial Building Sites: Labour, Skills and Construction Technologies encompasses a diverse range of temporal and geographical contexts, including examples from Africa and Asia. The aim is to facilitate a more nuanced and intricate comprehension of the construction site as a pivotal space that simultaneously supported and challenged colonialism across time and space.

    The contributions will include questions about authorship, construction materials and methods, design, architectural modernity, the coexistence of multiple skill sets, recruitment and urban unrest, the transfer of knowledge, and the dynamics of expertise.

    Em Fevereiro de 2025, Pedro Guedes visitou o nosso gabinete no Iscte. Trazia consigo duas pen drives com pastas de arquivos do pai – Pancho Guedes – que desejava partilhar. Entre o material de arquivo que partilhou estavam dois filmes, com 28’27 e 17’31 minutos, sobre os primeiros tempos da escola de Waterford, em cuja construção Pancho esteve envolvido entre 1961 e 1972. Os vídeos tinham-lhe chegado via email, através de uma rede ligada às históricas lutas políticas anti-segregacionistas da África do Sul. Este artigo é uma primeira tentativa de compreensão do processo de construção da actual escola Waterford Kamhlaba – United World College for Southern Africa, actual Essuatíni, a partir do primeiro filme, que assinala o arranque da constução da escola, entre 1962 e os primeiros meses de 1963, com uma câmara de filmar de Michael Stern, o seu primeiro director. Foi escrito a convite de Miguel Santiago, para uma edição comemorativa do centenário do nascimento de Pancho, publicada pela Fundação Serra Henriques.

    Summary

    The history of architecture and urban planning in former colonized territories has been shaped by canonical narratives and single agents (Lagae&Boonen, 2020). The question of architectural authorship has been at the center of most colonial studies, whether they focus on the designer, the engineer, the owner, or the political-administrative decision-maker who approved the territorial infrastructure, the urban settlement, or the building. “Can the subaltern speak” (Spivak, 1988) overcoming the architectural history focused on the designing elite? We welcome scholars to critically engage with the representativeness of labor subalternity and its importance throughout the process of architectural design and construction, questioning: who were those workers whose role was crucial to the colonial sphere, but who remained underrepresented in the history of colonial architecture? How did their labor, presence and skills influence the building site, construction methods and the project/design?
    This session intersects the history of colonial architecture and the theme of labor, encouraging scholars to submit papers that address the agency of labor in the Public Works Departments during the late colonial period, between the 19th and 20th centuries. Contributions related to the African and Asian contexts are particularly appreciated, as are those related to the history of colonial architecture focusing on the relationship between project design and unskilled labor and analyzing the impact of subalternised collective subjects (workers) who remained largely “hidden” in both colonial and postcolonial narratives. This session seeks for papers that explore the liaison between architecture, colonialism and labor, addressing: i) construction methods and skills; ii) construction sites; iii) authorship; iv) gender and race; v) division of labor. Researches based on both case studies and methodological approaches to the theme are welcome to enable a discussion on the impact of labor within the colonial architectural effort and how to approach it from a theoretical perspective.

    Summary

    The Benguela Railway represents one of the most significant mobility
    infrastructures developed during the Portuguese colonial period in Angola. The railroad was constructed between 1883 and 1931. The primary objective of the project was to establish a transportation network connecting the Lobito Port in Angola to the mineral- rich region of Katanga in the southern region of the former Belgian Congo. The construction was overseen by a private English company, yet it consistently received substantial support from the colonial state, particularly in terms of recruiting labor.

    A substantial body of research has been conducted on the political, economic, social, and territorial impacts of the Benguela Railway. The project’s promotion facilitated significant inter-imperial connections, the establishment of new settlements along the route, and the creation of an important transportation corridor that would serve a large area extending over 1,800 kilometers. However, the role and building skills of the thousands of African workers who participated in the construction of this line and associated buildings remain to be evaluated.

    This presentation aims to examine the impact of African workers on the building sites, mobile yards, and tasks along the construction of the Benguela Railway. The diversity of political, economic, and technological factors in this case study will be employed to examine the nature and evolution of the concept of “skill”. In particular, the paper will focus on the types of skills developed by the workers and the changes in discourse surrounding those skills over time and across diverse geographical locations. What insights can be gained from a more nuanced perspective that extends beyond the dichotomy of skill versus unskilled? The research will identify and compare information from different sources, including reports produced by the company and colonial inspectors, drawings, and photographs.
