Two Kings: Empire, Abolition, and the University of Aberdeen’s First African Student

This article presents a biography and multi-generational microhistory of Nathaniel King (1847–1884), the University of Aberdeen’s first African-born student and a pioneering practitioner of Western medicine in colonial West Africa. Nathaniel’s father, Thomas King, rose from slavery to become a missionary and linguist in Sierra Leone and what would later become Nigeria. Nathaniel, born to survivors of the Middle Passage, graduated M.B., C.M. from Aberdeen in 1876, before returning to West Africa to become a prominent member of the educated elite in Victorian Lagos. The long-established historiography of Scottish ‘sojourners’ abroad has not yet explored the impact of colonial sojourners to Scotland, an itinerary travelled particularly by male students from within the empire, especially as Scotland’s universities became imperial centres of medical training. This article draws particular attention to the significance of Britain’s nineteenth-century campaign against the trans-Atlantic slave trade in the arrival of the first African-born students at Scottish universities, placing King’s history within a broader pattern of Africans born to people liberated from slave ships who ventured to Aberdeen, Edinburgh, and St Andrews in the middle decades of the nineteenth century for medical training.

Lay Religious Associations in Extractive Zones: A Case Study of Diamantina, Brazil

This article considers religion in extractive zones by focusing on a religious practice in an extractive zone, namely, an Afro-Brazilian Irmandade (Catholic lay religious association) devoted to Our Lady of Mercy in Diamantina, Minas Gerais, Brazil. It adopts approaches from history and cultural studies to examine art, architecture, archives, and material culture, and brings these methodologies into conversation with Mary Louis Pratt’s notion of contact zones, Charles Long’s connection between these zones and new religious practices, Eduardo Gudynas’ definition of extraction, and Macarena Gómez-Barris’ decolonial methodologies for approaching the study of extractive zones. This study is contextualized in the history of mining in Brazil, the connection between mining and enslavement of Africans in the Americas, and the enduring legacy of lay religious associations in Brazil. The article then examines the association’s church, focusing on its late 18th and early 19th century façade and the statues at its main altar, and its 19th and 20th century maintenance records. It suggests that the Irmandades are engaged in a unique religious practice that arises within an extractive region because of specific historical, political, and social reasons, and that they give their members a place within the existing structures even as they challenge them.

Humphry Davy, transatlantic slavery and his constructions of racial difference in an early notebook

Humphry Davy was the most celebrated chemist of his day in Britain, but he has been absent from discussions of Romantic-era constructions of race. It is well known that Davy was an experimental chemist, popular lecturer, and, as has been recently explored by the Davy Notebooks Project, a poet; this essay expands this narrative to include his connection to transatlantic slavery and writing about race, which are neglected aspects of his life and writing. In this essay, I examine Davy’s response to the slave-trade debates and for the first time his close family links to transatlantic slavery, focusing on his wife Jane’s stepfather, the major enslaver, Robert Farquhar. I discuss Davy’s writing on the chemical causes of Black skin colour and a draft essay on the climate in notebook 13F in which he constructed the racial difference of Black Africans. I argue that his essay can be understood by recognizing 13F as a school notebook used during his period of self-education and that it reflects the messy and unstable nature of writing about race in the Romantic period. Davy’s racial thinking was influential and he was recognized as an authority on skin colour by his contemporaries, Thomas Beddoes, Johann Friedrich Blumenbach, and Sir Everard Home.

Intra-specific variations in Schistosoma mansoni and their possible contribution to inconsistent virulence and diverse clinical outcomes.

Schistosoma mansoni was introduced from Africa to the Americas during the transatlantic slave trade and remains a major public health problem in parts of South America and the Caribbean. This study presents a comprehensive comparative analysis of three S. mansoni strains with different geographical origins-from Liberia, Belo Horizonte and Puerto Rico. We demonstrated significant variation in virulence and host-parasite interactions. We investigated the phenotypic characteristics of the parasite and its eggs, as well as the immunopathologic effects on laboratory mouse organ systems. Our results show significant differences in worm morphology, worm burden, egg size, and pathologic organ changes between these strains. The Puerto Rican strain showed the highest virulence, as evidenced by marked liver and spleen changes and advanced liver fibrosis indicated by increased collagen content. In contrast, the strains from Liberia and Belo Horizonte had a less pathogenic profile with less liver fibrosis. We found further variations in granuloma formation, cytokine expression and T-cell dynamics, indicating different immune responses. Our study emphasizes the importance of considering intra-specific variations of S. mansoni for the development of targeted therapies and public health strategies. The different virulence patterns, host immune responses and organ pathologies observed in these strains provide important insights for future research and could inform region-specific interventions for schistosomiasis control.

Between abolition and opium: civility and force across Asian and Caribbean British imperialisms

ABSTRACT This paper explores the relationship between Britian’s abolition of slavery in its Caribbean colonies in 1838 and its instigation of the First Opium War with China in 1840. In so doing, it works against the occlusion of this relationship in the study of British imperialism despite the centrality of these events to the birth of global systems of free trade and free labour. It draws on the parliamentary debates and correspondence of British Foreign Secretary Lord Palmerston to analyze Britain’s negotiation of anti-slavery efforts with Haiti and its trade of Indian opium with China. It argues that these negotiations position British masculine civility against less-civilized foreign others in ways that legitimate the use of maritime force. This logic of imperial civility produces contradictory effects by demanding an end to the brutality of African enslavement while condoning the devastation of Asian opium addiction enacted in the name of free trade.

Musicians, Chariot Bearers, and Ghost Characters: The Spectrality of Black Slavery in Early Modern Mediterranean Drama

The article discusses early modern English plays from the 1590s to the 1610s, set in or referring to the Mediterranean, which feature Black African characters in marginal roles. These characters are ‘spectral’ in that they have no speaking part but appear briefly as attendants, servants, musicians, or indeed slaves. The article argues that their spectrality evokes the presence of Black African slaves in the Mediterranean, which has often been ignored in Early Modern Studies. However, through these characters Black slavery is turned into a mere spectacle, performed for the gaze of the theatre audience in early modern London.

Nested admixture during and after the Trans-Atlantic Slave Trade on the island of São Tomé.

Human admixture history is rarely a simple process in which distinct populations, previously isolated for a long time, come into contact once to form an admixed population. In this study, we aim to reconstruct the complex admixture histories of the population of São Tomé, an island in the Gulf of Guinea that was the site of the first slave-based plantation economy, and experienced successive waves of forced and deliberate migration from Africa. We examined 2.5 million SNPs newly genotyped in 96 São Toméans and found that geography alone cannot explain the observed patterns of genetic differentiation within the island. We defined five genetic groups in São Tomé based on the hypothesis that individuals sharing the most haplotypes are more likely to share similar genetic histories. Using Identical-by-Descent and different local ancestry inference methods, we inferred shared ancestries between 70 African and European populations and each São Toméan genetic group. We identified admixture events between admixed groups that were previously isolated on the island, showing how recently admixed populations can be themselves the sources of other admixture events. This study demonstrates how complex admixture and isolation histories during and after the Transatlantic Slave-Trade shaped extant individual genetic patterns at a local scale in Africa.

Epistemic silences, subversive politics: post-disaster economic assessments as technologies of persistent coloniality and route to an emancipatory climate justice agenda in the Caribbean

ABSTRACT Economic analyses of losses and damages or post-disaster needs assessments (PDNAs) are silent about the longstanding reparatory claims related to the legacies of African enslavement, colonial violence and indigenous dispossession that compound uneven racialized geographies in the Caribbean. This paper unpacks these so-called ‘objective’ valuations drawing attention to their (neo)liberal framings, technocratic underpinnings, and historical origins in the Caribbean plantation economy. Using case studies of catastrophic hurricanes Matthew (2016), Irma (2017) and Dorian (2019) in Haiti, Antigua and Barbuda, and The Bahamas respectively, the paper exposes critical tensions, knowledge hierarchies, and contradictions embedded within empirical assessments that justify and prioritize preferred policies of powerful international development, financial and governance institutions. PDNAs under-value and neglect important community and local knowledge, solidarity practices, cultural institutions, and relational ethics in the face of climate disasters in these Caribbean islands. Taking a Black geographies and political economy approach, the paper addresses the limitations and risks associated with PDNAs, deemed political tools or technologies of climate disaster that reinforce oppression. To advance an emancipatory climate justice agenda to enable more radical reparative measures and possibilities, the paper suggests that analyses and political strategy must be grounded in people's history, cultural, ethical, and communal governance practices.

Maroon Rice Genomic Diversity Reflects 350 Years of Colonial History.

Maroons in Suriname and French Guiana descend from enslaved Africans who escaped the plantations during colonial times. Maroon farmers still cultivate a large diversity of rice, their oldest staple crop. The oral history and written records of Maroons by colonial authorities provide contrasting perspectives on the origins of Maroon rice. Here, we analyzed the genomic ancestry of 136 newly sequenced Maroon rice varieties and found seven genomic groups that differ in their geographical associations. We interpreted these findings in light of ethnobotanical and archival investigations to reconstruct the historical contexts associated with the introduction of rice varieties to the Guianas. We found that two rice groups trace to West Africa, which we propose are linked to the transatlantic slave trade (c. 1526 to 1825). We posit that the Maroon rice stock additionally contains varieties that derive from rice introduced by indentured laborers from Java (1890 onwards), USA rice breeders (1932 onwards), and Hmong refugees who fled the Vietnam War (1991). Furthermore, on the Maroon fields, we found rice types never documented before that were derived from crosses. Overall, our results demonstrate that the Maroon farmers prioritize maintenance of a high stock diversity, which we posit reflects the expertise they inherited from their (African) ancestors. Ignored by agricultural modernization initiatives, Maroon farmers today are custodians of a unique cultural heritage. Notably, the genomic findings underline many Maroon stories about their past. We anticipate that a similar study approach can be applied to other heirloom crops of (Indigenous) communities that may have preserved their history on their farms to reconstruct, acknowledge, and honor the past.

Irish Immigrants in Colonial Port Cities of Cuba: Havana, Santiago, and Cienfuegos

Abstract The port city of Havana, central to the Spanish colonial fleet system since the late sixteenth century, remained an important nexus for nineteenth-century Atlantic trade networks of sugar, coffee, tobacco, and the slave trade. Positioning Irish immigrants in this global hub allows us to examine their presence in Cuba and their participation in global circuits of commodities, trade, and labor. Drawing on local colonial sources, we evaluate the opportunities and experiences of Irish immigrants as social actors in the multi-ethnic urban spaces of Havana and other strategically located port cities of Santiago and Cienfuegos. The Irish who converged on Cuba rarely came directly from Ireland. Hence, we explore three migration trajectories mediated through the British West Indies, the Spanish metropole, and globally connected cities of North America. The most prominent were high-ranking military men who arrived in Cuba in the eighteenth century through Iberian-Irish connections; a smaller number of propertied Irish who migrated from the West Indies; and lastly, distinct flows of largely anonymous nineteenth-century immigrants who came through emerging Atlantic networks of colonial labour via the United States. This study explores the entangled histories of Irish, African, and European diasporas in the social and political worlds of three Spanish Caribbean port cities. Through an analysis of how Irish immigrants negotiated processes of class, religion, race, and gender in colonial Cuba, we highlight their participation in key economic and social dynamics of white colonization strategies, plantation slavery, and the Atlantic slave trade.

KNUST SEG Geophysics Field Camp: A project to study slavery-related archaeology in West Africa

In this article, we describe a field camp in West Africa that explored the use of geophysics in archaeological investigations related to the transatlantic slave trade. Africa's geodiversity and richness of natural resources makes geoscience education essential for social, academic, scientific, and professional growth and development. Field camps serve as a pivotal element of geoscience pedagogy, providing hands-on experiential learning opportunities for budding geoscientists. Due to a lack of funding, there is limited access to and availability of geoscience field camps for students and early-career professionals in Africa. The main goal of our field camp was to delineate archaeological relics related to the transatlantic slave trade in the southeastern part of Ghana. The field camp provided a way to conduct research and train geoscience students in planning and performing geophysical investigations. It also taught students how to process and interpret geophysical data and prepare and present scientific investigation reports. We investigated sites in Aflao, Denu, Hedzranawo, and Keta in the southeastern part of Ghana. Sites of interest included former slave markets, barracoons, and a fort. The project highlighted locations of potential slavery-related archaeological relics and shared the importance of the findings and their implications for understanding the history of transatlantic slavery in Ghana.

From Valuable Merchandise to Violent Rebels

From the moment the Dutch West Indian Company formally entered the slave trade in 1637, the Dutch periodical press consistently carried reports on slavery and the transatlantic slave trade. This article offers a long-term analysis of this coverage in the Dutch Republic, showing for the first time how the representation of slavery developed over the seventeenth and eighteenth centuries. It demonstrates, first, that through the periodical press, knowledge of slavery was more widely spread in the Dutch Republic in the seventeenth century than is often assumed. The consistent, if intermittent, newspaper coverage meant that – well before the debates on abolition emerged – Dutch readers would be familiar with stereotypes of enslaved Africans as valuable merchandise or violent rebels. Second, this article argues that, in the second half of the eighteenth century, the periodical press offered its readers an ambiguous and contradictory image of slavery, contributing, on the one hand, to a public discourse underpinning slavery by depicting enslaved Africans as violent rebels, while at the same time covering political debates on the abolition of slavery.

WHAT IS HISTORY IN A SETTLER COLONIAL SOCIETY? MAPPING THE LIMITS AND POSSIBILITIES OF ETHICAL HISTORIOGRAPHY USING AN AUSTRALIAN CASE STUDY

ABSTRACTIn recent decades, the role of the history discipline as part of the architecture of colonization has become more visible and better understood. Such acknowledgement reflects foundational shifts in historical practice and theory prompted by transdisciplinary and transnational scholarship in fields such as postcolonial and settler‐colonial studies, First Nations knowledges, and historical perspectives and practices contextualized by transatlantic slavery. Their intervention in turn prompted a vital question: How do we map settler‐colonial historiography if the discipline has been complicit in the settler‐colonial project? Using Australian historiography as a case study, this article explores how History has been part of the architecture of colonization, policing whose stories can be told and by whom. Drawing on the work of Indigenous history‐makers and knowledge‐holders, it also points to ways that researchers might reach outside the traditional scope of historiography to map and contemplate the range of history‐making that comprises history in the settler colony.

‘Comrade unknown to me’: colonialism, modernity, and conjunctural translation in Familiar Stranger

ABSTRACT This essay considers the possibility of what I would call conjunctural translation. While literal translation has accelerated cultural ethnocentrism as well as settler colonial violence, conjunctural translation seeks to glimpse the possibility of solidarity buried beneath the collaborative rule among the empires. This essay first retraces colonial modernity in the British Caribbean and Britain. Reading the selected chapters from Familiar Stranger, I propose that this memoir registers the three phases of colonial modernity: transatlantic slavery, migration to metropolis, and the prison-house of identity politics. In contrast to this, literal translation was at the core of cultural ethnocentrism that underpinned colonial modernity in Korea and Japan. The second part of this essay explicates the relationship between colonialism and modernity in East Asia that is punctuated by the following three phases: settler colonialism, migration to metropolises, and the curtailment of identity and citizenship. In this case, each phase appeared as deprivation of land, migration to Japan and the crises of security, and the loss of nationality during the Cold War era. The last part of the essay concerns unpredictable connections between colonial modernities. Though separately formed in the transatlantic and transpacific regions, these modernities create crosscurrents of thought, struggles, defeats and victories: conjunctures. Published in the early 1950s, the writings of Martin Carter and C. L. R. James differently refer to the Korean War. By comparing their work, this essay concludes that the future of solidarity comes from ‘the ability to be exposed’. As Hall unexpectedly encountered the Caribbean migrants in London in the key moments of his memoir, such conjunctural translation was undertaken by the Caribbean intellectuals of the 1950s. To expose oneself to these unexpected encounters is the very momentum that urges us to be vigilant to the dangers of literal translation.

Shameful Specters: Remembering Spanish Slavery in Àngels Aymar’s La Indiana

Abstract This article reveals a new figure in the contemporary Spanish imaginary, the indiana, and a new literary mode, the indiana melodrama. It argues that the incarnation of the indiana as a virtuous, melodramatic heroine in Àngels Aymar’s 2007 play La indiana rebukes Spanish participation in transatlantic slavery and counters the historical amnesia that Spanish culture frequently displays toward its colonial past. An early forerunner in Spain’s long-delayed path to recognizing its history of slavery, La indiana forms part of activist efforts in Catalonia, the autonomous community in which the play premiered. Applying theories of memory and melodrama, the article explains how many factors in the play—the actors, their voices, the stage space, the soundscape, and the mixing of the Catalan and Spanish languages—transmit memory across racial, temporal, and spatial boundaries. This effect, “theatrical postmemory,” minimizes the distance between past and present, Cuba and Catalonia, memory and history. The article focuses on Aymar’s transformation of two symbols of Spanish (post)imperial nostalgia, the indiano home and the Catalan habanera, a popular musical genre. La indiana deconstructs the melodramatic convention of a happy ending and the concomitant restoration of innocence.

Robert Bernasconi and the challenges of a Critical Philosophy of Race: (Un)learning to read and teach the history of moral philosophy

This essay is an attempt to determine what Robert Bernasconi’s body of work in Critical Philosophy of Race can teach us about the way in which we, philosophers and professors of philosophy, ought to treat our institutional heritage. What should we make, for instance, of moral claims made by philosophers of the modern era who – tacitly or explicitly – manifested certain levels of endorsement toward the Atlantic Slave Trade? How should we comprehend the conceptual tools that we have inherited from them, knowing that those were formulated alongside justificatory claims for the enslavement of Africans – claims that we now deem undoubtably and universally immoral? I extract from Bernasconi’s writings an implicit methodology that can be broken down into three main moves: (1) a historiographical work, akin to Michel Foucault’s ‘archaeological’ method, aimed at uncovering the material conditions that allowed for the emergence of philosophical ideas of the past, (2) a dialectical work aimed at interpreting this collection of historical data through the critical lens of race, and (3) a pedagogical work aimed at transforming the practice of academic philosophy in light of the critique. I conclude that his methodological contribution culminates in an invitation to revisit and transform the past of the institution by treating the history of academic philosophy as philosophically and conceptually relevant rather than merely incidental. Such a commitment toward critically engaging the past of our institution urges us to revisit the canon in specific ways.

Augmenting the availability of historical GDP per capita estimates through machine learning

Can we use data on the biographies of historical figures to estimate the GDP per capita of countries and regions? Here, we introduce a machine learning method to estimate the GDP per capita of dozens of countries and hundreds of regions in Europe and North America for the past seven centuries starting from data on the places of birth, death, and occupations of hundreds of thousands of historical figures. We build an elastic net regression model to perform feature selection and generate out-of-sample estimates that explain 90% of the variance in known historical income levels. We use this model to generate GDP per capita estimates for countries, regions, and time periods for which these data are not available and externally validate our estimates by comparing them with four proxies of economic output: urbanization rates in the past 500 y, body height in the 18th century, well-being in 1850, and church building activity in the 14th and 15th century. Additionally, we show our estimates reproduce the well-known reversal of fortune between southwestern and northwestern Europe between 1300 and 1800 and find this is largely driven by countries and regions engaged in Atlantic trade. These findings validate the use of fine-grained biographical data as a method to augment historical GDP per capita estimates. We publish our estimates with CI together with all collected source data in a comprehensive dataset.

The Politics of a Portrait: Biopics, Slavery and Contemporary Racial Politics in the United States

The article examines the connection between the past and the present, and between the personal and the political, in three recent biographical pictures directed by filmmakers of color: The Birth of a Nation (2016, dir. Nate Parker), Harriet (2018, dir. Kasi Lemmons), and Emancipation (2022, dir. Antoine Fuqua). By addressing the history of American slavery, the films not only come into a dialogue with the preexisting representations of slavery in music, photography and cinema, but also reflect on current racial politics and antiracist activism in the United States. They offer a commentary on changing attitudes towards the issue of race in America, and engage with the collective memory of slavery - a past trauma, which has shaped the African American identity.

CORRECTING MODEL MISSPECIFICATION IN RELATIONSHIP ESTIMATES.

The datasets of large genotyping biobanks and direct-to-consumer genetic testing companies contain many related individuals. Until now, it has been widely accepted that the most distant relationships that can be detected are around fifteen degrees (approximately 8 th cousins) and that practical relationship estimates have a ceiling around ten degrees (approximately 5 th cousins). However, we show that these assumptions are incorrect and that they are due to a misapplication of relationship estimators. In particular, relationship estimators are applied almost exclusively to putative relatives who have been identified because they share detectable tracts of DNA identically by descent (IBD). However, no existing relationship estimator conditions on the event that two individuals share at least one detectable segment of IBD anywhere in the genome. As a result, the relationship estimates obtained using existing estimators are dramatically biased for distant relationships, inferring all sufficiently distant relationships to be around ten degrees regardless of the depth of the true relationship. Existing relationship estimators are derived under a model that assumes that each pair of related individuals shares a single common ancestor (or mating pair of ancestors). This model breaks down for relationships beyond 10 generations in the past because individuals share many thousands of cryptic common ancestors due to pedigree collapse. We first derive a corrected likelihood that conditions on the event that at least one segment is observed between a pair of putative relatives and we demonstrate that the corrected likelihood largely eliminates the bias in estimates of pairwise relationships and provides a more accurate characterization of the uncertainty in these estimates. We then reformulate the relationship inference problem to account for the fact that individuals share many common ancestors, not just one. We demonstrate that the most distant relationship that can be inferred using IBD may be 200 degrees or more, rather than ten, extending the time-to-common ancestor from approximately 300 years in the past to approximately 3,000 years in the past or more. This dramatic increase in the range of relationship estimators makes it possible to infer relationships whose common ancestors lived before historical events such as European settlement of the Americas, the Transatlantic Slave Trade, and the rise and fall of the Roman Empire.
