Dental disease in a 15th-17th centuries skeletal sample of enslaved Africans (Lagos, Portugal).

OBJECTIVE: Dental disease is frequently used as a proxy for diet and overall health of individuals of past populations. The aim of this study is to investigate dental disease in a sample of enslaved African individuals recovered from an urban dump (15th-17th centuries) in Lagos, Portugal. DESIGN: In all, 81 African individuals (>12 years old) were analysed (19 males, 49 females, and 13 of unknown sex), in a total of 2283 alveoli, 2061 teeth, and 2213 interdental septa. Analysed oral pathologies include dental caries, periodontal disease, and ante-mortem tooth loss. Dental wear was also recorded. RESULTS: Dental caries affected 52.0 % of the teeth, although only 31.9 % were cavitated lesions. In all, 96.3 % of the individuals presented at least one cariogenic lesion. Gingivitis and periodontitis were recorded in 56.7 % and 19.0 % of the septa, respectively. Only one male individual had all septal areas healthy. Ante-mortem tooth loss was recorded in 38.3 % of the individuals, in a total of 96 teeth lost (4.2 %). Regarding occlusal wear, 70.8 % of the surfaces were recorded with grades 1-3. CONCLUSIONS: The frequencies of the oral pathological conditions observed may not only reflect a cariogenic diet (rich in starches and with a high frequency of meals) but also the conditions during the maritime voyage of the first victims of the North Atlantic slave trade (xerostomia due to lack of water, sea sickness and vomiting, vitamin C deficiency, poor hygiene), and also the impact intentional dental modifications had on the dentitions.

Spatiotemporal Changes in the Slavery-Inequality Relationship: The Diffusion of the Legacy of Slavery.

Despite the persistence of relationships between historical racist violence and contemporary Black-White inequality, research indicates, in broad strokes, that the slavery-inequality relationship in the United States has changed over time. Identifying the timing of such change across states can offer insights into the underlying processes that generate Black-White inequality. In this study, we use integrated nested Laplace approximation models to simultaneously account for spatial and temporal features of panel data for Southern counties during the period spanning 1900 to 2018, in combination with data on the concentration of enslaved people from the 1860 census. Results provide the first evidence on the timing of changes in the slavery-economic inequality relationship and how changes differ across states. We find a region-wide decline in the magnitude of the slavery-inequality relationship by 1930, with declines traversing the South in a northeasterly-to-southwesterly pattern over the study period. Different paces in declines in the relationship across states suggest the expansion of institutionalized racism first in places with the longest-standing overt systems of slavery. Results provide guidance for further identifying intervening mechanisms-most centrally, the maturity of racial hierarchies and the associated diffusion of racial oppression across institutions, and how they affect the legacy of slavery in the United States.

"Appalling mortality": disembarkation, demographics, and African diseases. / "Espantosa mortandade": desembarques, demografias e enfermidades africanas.

This article contributes to a better understanding of the conditions which Africans endured immediately after landing in Brazil, taking the study beyond what happened in the slave ships. It highlights the importance of Eastern Africans in the southeast of Brazil, in the beginning of the nineteenth century, something that must be considered in order to do a deeper analysis of identity reinventions, diseases, and healing practices. The background of the suffering of those people can be found in the debates and political negotiations surrounding the prohibition of the Atlantic slave trade and the independence of Brazil.

Este artigo contribui para conhecermos melhor as condições a que africanos estavam submetidos no imediato desembarque, estendendo o estudo para além do navio. Destaca a importância dos africanos orientais no Sudeste brasileiro no início do século XIX, o que deve ser considerado para o aprofundamento da análise sobre reinvenções identitárias, doenças e práticas de cura. As dores dessas pessoas tiveram como pano de fundo os debates e as negociações políticas em torno da proibição do tráfico atlântico e da independência do Brasil.

Ancient viral genomes reveal introduction of human pathogenic viruses into Mexico during the transatlantic slave trade.

After the European colonization of the Americas, there was a dramatic population collapse of the Indigenous inhabitants caused in part by the introduction of new pathogens. Although there is much speculation on the etiology of the Colonial epidemics, direct evidence for the presence of specific viruses during the Colonial era is lacking. To uncover the diversity of viral pathogens during this period, we designed an enrichment assay targeting ancient DNA (aDNA) from viruses of clinical importance and applied it to DNA extracts from individuals found in a Colonial hospital and a Colonial chapel (16th-18th century) where records suggest that victims of epidemics were buried during important outbreaks in Mexico City. This allowed us to reconstruct three ancient human parvovirus B19 genomes and one ancient human hepatitis B virus genome from distinct individuals. The viral genomes are similar to African strains, consistent with the inferred morphological and genetic African ancestry of the hosts as well as with the isotopic analysis of the human remains, suggesting an origin on the African continent. This study provides direct molecular evidence of ancient viruses being transported to the Americas during the transatlantic slave trade and their subsequent introduction to New Spain. Altogether, our observations enrich the discussion about the etiology of infectious diseases during the Colonial period in Mexico.

The arrival of European colonists to the Americas, beginning in the 15^th century, contributed to the spread of new viruses amongst Indigenous people. This led to massive outbreaks of disease, and millions of deaths that caused an important Native population to collapse. The exact viruses that caused these outbreaks are unknown, but smallpox, measles, and mumps are all suspected. During these times, traders and colonists forcibly enslaved and displaced millions of people mainly from the West Coast of Africa to the Americas. The cruel, unsanitary, and overcrowded conditions on ships transporting these people across the Atlantic contributed to the spread of infectious diseases onboard. Once on land, infectious diseases spread quickly, partly due to the poor conditions that enslaved and ndigenous people were made to endure. Native people were also immunologically naïve to the newly introduced pathogens, making them susceptible to severe or fatal outcomes. The new field of paleovirology may help scientists identify the viruses that were circulating in the first years of colonization and trace how viruses arrived in the Americas. Using next-generation DNA sequencing and other cutting-edge techniques, Guzmán-Solís et al. extracted and enriched viral DNA from skeletal remains dating back to the 16^th century. These remains were found in mass graves that were used to bury epidemic victims at a colonial hospital and chapel in what is now Mexico City. The experiments identified two viruses, human parvovirus B19 and a human hepatitis B virus. These viral genomes were recovered from human remains of first-generation African people in Mexico, as well as an individual who was an Indigenous person. Although the genetic material of these ancient viruses resembled pathogens that originated in Africa, the study did not determine if the victims died from these viruses or another cause. On the other hand, the results indicate that viruses frequently found in modern Africa were circulating in the Americas during the slave trade period of Mexico. Finally, the results provide evidence that colonists who forcibly brought African people to the Americas participated in the introduction of viruses to Mexico. This constant influx of viruses from the old world, led to dramatic declines in the populations of Indigenous people in the Americas.

#SayHerName: Should Obstetrics and Gynecology Reckon with the Legacy of JM Sims?

Dr. James Marion Sims has been heralded as the "father of modern gynecology" for his groundbreaking surgical technique to repair post-partum vesicovaginal fistulas (VVF); however, the ethical concerns around his inhumane practices and the contributions of the enslaved women he refined his technique on are rarely recognized. Acknowledging the personal sacrifice of the enslaved women and addressing the truth behind the immoral practices of Sims, encourages reconciliation of the race-based medical atrocities of the past and sets the tone for moral, more equitable medical care moving forward.

Anthropological genetics perspectives on the transatlantic slave trade.

During the Trans-Atlantic Slave Trade (TAST), around twelve million Africans were enslaved and forcibly moved from Africa to the Americas and Europe, durably influencing the genetic and cultural landscape of a large part of humanity since the 15th century. Following historians, archaeologists, and anthropologists, population geneticists have, since the 1950's mainly, extensively investigated the genetic diversity of populations on both sides of the Atlantic. These studies shed new lights into the largely unknown genetic origins of numerous enslaved-African descendant communities in the Americas, by inferring their genetic relationships with extant African, European, and Native American populations. Furthermore, exploring genome-wide data with novel statistical and bioinformatics methods, population geneticists have been increasingly able to infer the last 500 years of admixture histories of these populations. These inferences have highlighted the diversity of histories experienced by enslaved-African descendants, and the complex influences of socioeconomic, political, and historical contexts on human genetic diversity patterns during and after the slave trade. Finally, the recent advances of paleogenomics unveiled crucial aspects of the life and health of the first generation of enslaved-Africans in the Americas. Altogether, human population genetics approaches in the genomic and paleogenomic era need to be coupled with history, archaeology, anthropology, and demography in interdisciplinary research, to reconstruct the multifaceted and largely unknown history of the TAST and its influence on human biological and cultural diversities today. Here, we review anthropological genomics studies published over the past 15 years and focusing on the history of enslaved-African descendant populations in the Americas.

Ancestry, health, and lived experiences of enslaved Africans in 18th century Charleston: An osteobiographical analysis.

OBJECTIVES: In 2013, the burials of 36 individuals of putative African ancestry were discovered during renovation of the Gaillard Center in downtown Charleston, South Carolina. The Charleston community facilitated a bioarchaeological and mitogenomic study to gain insights into the lives of these unknown persons, referred to as the Anson Street Ancestors, including their ancestry, health, and lived experiences in the 18th century. METHODS: Metric and morphological assessments of skeletal and dental characteristics were recorded, and enamel and cortical bone strontium stable isotope values generated. Whole mitochondrial genomes were sequenced and analyzed. RESULTS: Osteological analysis identified adults, both females and males, and subadults at the site, and estimated African ancestry for most individuals. Skeletal trauma and pathology were infrequent, but many individuals exhibited dental decay and abscesses. Strontium isotope data suggested these individuals mostly originated in Charleston or sub-Saharan Africa, with many being long-term residents of Charleston. Nearly all had mitochondrial lineages belonging to African haplogroups (L0-L3, H1cb1a), with two individuals sharing the same L3e2a haplotype, while one had a Native American A2 mtDNA. DISCUSSION: This study generated detailed osteobiographies of the Anson Street Ancestors, who were likely of enslaved status. Our results indicate that the Ancestors have diverse maternal African ancestries and are largely unrelated, with most being born locally. These details reveal the demographic impact of the trans-Atlantic slave trade. Our analysis further illuminates the lived experiences of individuals buried at Anson Street, and expands our understanding of 18th century African history in Charleston.

Structural Racism and Maternal Health Among Black Women.

Historical foundations rooted in reproductive oppression have implications for how racism has been integrated into the structures of society, including public policies, institutional practices, and cultural representations that reinforce racial inequality in maternal health. This article examines these connections and sheds light on how they perpetuate both racial disparities in maternal health and high rates of maternal mortality and morbidity among Black women.

[Genetic traces of the trans-Atlantic slave trade]. / Les traces génétiques de la traite des esclaves - Chroniques génomiques.

More than 10 million enslaved Africans were transported to the Americas between 1500 and 1900. Recent genetic studies investigate regional African ancestry components in present-day Africa-Americans, and allow comparison with the extensive records documenting these deportations. The genetic evidence generally agrees with the historical records but brings additional insights in this dark episode of human history.

Origin and Health Status of First-Generation Africans from Early Colonial Mexico.

The forced relocation of several thousand Africans during Mexico's historic period has so far been documented mostly through archival sources, which provide only sparse detail on their origins and lived experience. Here, we employ a bioarchaeological approach to explore the life history of three 16th century Africans from a mass burial at the San José de los Naturales Royal Hospital in Mexico City. Our approach draws together ancient genomic data, osteological analysis, strontium isotope data from tooth enamel, δ13C and δ15N isotope data from dentine, and ethnohistorical information to reveal unprecedented detail on their origins and health. Analyses of skeletal features, radiogenic isotopes, and genetic data from uniparental, genome-wide, and human leukocyte antigen (HLA) markers are consistent with a Sub-Saharan African origin for all three individuals. Complete genomes of Treponema pallidum sub. pertenue (causative agent of yaws) and hepatitis B virus (HBV) recovered from these individuals provide insight into their health as related to infectious disease. Phylogenetic analysis of both pathogens reveals their close relationship to strains circulating in current West African populations, lending support to their origins in this region. The further relationship between the treponemal genome retrieved and a treponemal genome previously typed in an individual from Colonial Mexico highlights the role of the transatlantic slave trade in the introduction and dissemination of pathogens into the New World. Putting together all lines of evidence, we were able to create a biological portrait of three individuals whose life stories have long been silenced by disreputable historical events.

From ethnobotany to emancipation: Slaves, plant knowledge, and gardens on eighteenth-century Isle de France.

This essay examines the relationship between slavery and plant knowledge for cultivational activities and medicinal purposes on Isle de France (Mauritius) in the second half of the eighteenth century. It builds on recent scholarship to argue for the significance of slaves in the acquisition of plant material and related knowledge in pharmaceutical, acclimatization, and private gardens on the French colonial island. I highlight the degree to which French colonial officials relied on slaves' ethnobotanical knowledge but neglected to include such information in their published works. Rather than seeking to explore the status of such knowledge within European frameworks of natural history as an endpoint of knowledge production, this essay calls upon us to think about the plant knowledge that slaves possessed for its practical implementations in the local island context. Both female and male slaves' plant-based knowledge enriched - even initiated - practices of cultivation and preparation techniques of plants for nourishment and medicinal uses. Here, cultivational knowledge and skills determined a slave's hierarchical rank. As the case of the slave gardener Rama and his family reveals, plant knowledge sometimes offered slaves opportunities for social mobility and, even though on extremely rare occasions, enabled them to become legally free.

How the public autopsy of a slave Joice Heth launched P.T. Barnum's career as the Greatest Showman on Earth.

P.T. Barnum's career as the Greatest Showman on Earth began in 1835, when he "leased" and then publically exhibited a frail African American slave Joice Heth, who was reportedly the 161-year-old former nursemaid of George Washington, throughout New England; the contract was a lease, as slave ownership had recently become illegal in northern states. Barnum exhibited Heth 6 days a week for up to 12 hr a day. Under this grueling schedule, Heth became ill and died while under contract. Barnum sold tickets for her autopsy, which was performed by David L. Rogers, an accomplished New York surgeon, in front of an audience of 1,500 paying customers. Roger's autopsy determined that Heth was no more than 80 years old, and the penny newspapers, a new form of public media, called this a "humbug" and then published dozens of fabricated "fake news" stories about Barnum, Rogers, and Heth. Barnum and his business partner generated valuable publicity by telling different penny newspapers different stories. This whole spectacle launched Barnum's career as an entertainer. Five years earlier, Rogers performed a public dissection of Charles Gibbs, an infamous Caribbean pirate who was tried, convicted, and hung in New York City. This article describes the bizarre nature of American politics and culture in the 1830s that made all of these seem normal. I will also distinguish between "public dissection" and "public autopsy," and put these into an historical context. Finally, I will address the macabre concept of autopsy as a form of entertainment.

As famílias de povoadores em áreas de fronteira da Capitania de São Paulo na segunda metade do século XVIII / Families settlers in border areas of the captaincy of São Paulo during the second half of the 18th century / Las familias de colonos en las zonas fronterizas de la Capitanía de São Paulo durante la segunda mitad del siglo XVIII

Ao tomar posse do governo da capitania de São Paulo em 1765, o Morgado de Mateus instaurou um processo de expansão do povoamento. A crise da economia colonial e os conflitos com os castelhanos exigia a intervenção da Coroa, que buscava implantar novas atividades econômicas e preparar a defesa do território. Ao criar vilas e povoados, o governador buscou reunir indivíduos que classificava como desregrados e os enviou, algumas vezes à força, para serem os pioneiros nestas áreas de fronteira. Muitos desses povoadores eram indígenas, considerados vadios, e que deviam ser submetidos ao novo modelo de organização social proposto pela Coroa. Este esforço pode ser avaliado a partir das listas nominativas de habitantes de três destas iniciativas de povoamento: São Luiz do Paraitinga, Piracicaba e o Caminho de Goiás. A análise do perfil dos indivíduos instalados nestas novas povoações permite melhor entender as estratégias de organização da população colonial desejadas pela Coroa.

After assuming the Government of the captaincy of São Paulo in 1765, Morgado de Mateus established an expansion process of the settlement. The crisis of the colonial economy and conflicts with the Castilians demanded the intervention of the Crown, seeking to deploy new economic activities and preparing the defense of the territory. When creating towns and villages, the Governor would seek bringing together individuals classified as unruly and would send them, sometimes by force, to be the pioneers in border areas. Many of these settlers were indigenous people, considered as vagabonds, who should be submitted to the new model of social organization proposed by the Crown. This effort can be accessed through inhabitants lists of three settlement initiatives: São Luiz do Paraitinga, Piracicaba and the Caminho de Goiás. The profile analysis of the individuals installed in these new villages allows for a better understanding of the organizational strategies of the colonial population desired by the Crown.

The Medicinal Rod: Slave Health and Redhibition Law in George Washington Cable's The Grandissimes.

The economic transactions and litigation necessary for slavery to function, coupled with the South's honor culture, meant skepticism and posturing frequently attended the buying and selling of enslaved people. This atmosphere provided opportunities for enslaved individuals familiar with the symbiotic ways their health and value intertwined to manipulate owners by feigning illness or adopting behaviors contrary to those of a "sound and sane" captive under Louisiana's redhibitory (slave warranty) law. Such actions offered a chance at preserving that which slavery denied its victims: proximity to family, a reduced chance of being sold, and an opportunity to exert agency within a strictly oppressive system. In dramatizing these paradoxes, George Washington Cable's The Grandissimes illustrates the vile hollowness of owners' paternalistic attitudes towards the enslaved, acknowledges the subjectivity and will of enslaved individuals, and castigates the return of slavery-like conditions in the form of the convict lease system.

The biological standard of living in pre-modern Korea: Determinants of height of militia recruits during the Choson dynasty.

This paper extends the research on the biological standard of living in the Korean peninsula back to pre-modern times. Drawing on militia rosters of the Choson Dynasty from the sixteenth to eighteenth centuries, we tentatively conclude that the final height of Korean men during this period was 166cm and thus slightly above that of modern North Korean men (165cm). On the other hand, the average height of modern South Korean men is 172cm, 6cm more than what we tentatively estimate for pre-modern Korean men. Regression analysis of the height of pre-modern Korean men finds that un-free Koreans ("slaves") were significantly shorter by about 0.6-0.7cm than commoners, whereas the average height of recruits suffering from smallpox did not differ significantly from that of other recruits. Moreover, regional, as opposed to birth-dummy, variables account, and to a significant degree, for most of the differences in height. Whether or not this is a result of socioeconomic differences across provinces or a result of other regionally-varying factors remains an open question.
