SUMMARYCystic echinococcosis, caused by different species of the Echinococcus granulosus complex, is an important zoonotic disease with a particular impact on pastoralist societies. In addition to the widespread taxa with synanthropic transmission, a number of Echinococcus species were described from African wild carnivores early in the 20th century. For lack of study material, most of these were later tentatively synonymized with E. granulosus. Early infection experiments with wildlife isolates gave ambiguous results due to the use of unspecified parasite material, and only recently molecular methods provided the opportunity to shed light on the confusing scenery e.g. by characterizing E. felidis from the African lion. Here we will summarize the convoluted history of Echinococcus research in sub-Saharan Africa and highlight the necessity of molecular surveys to establish the life cycles and estimate the zoonotic potential of these parasites.

Christianity came very early to Africa, as attested by the Gospels. The agencies by which it spread across North Africa and into the Kingdom of Aksum remain largely unknown. Even after the rise of Islam cut communications between sub-Saharan Africa and the churches of Rome and Constantinople, it survived in the eastern Sudan kingdom of Nubia until the 15th century and never died in Ethiopia. The documentary history of organized missions begins with the Roman Catholic monastic orders founded in the 13th century. Their evangelical work in Africa was closely bound up with Portuguese colonialism, which both helped and hindered their operations. Organized European Protestant missions date from the 18th-century evangelical awakening and were much less creatures of states. Africa was a particular object of attention for Evangelicals opposed to slavery and the slave trade. Paradoxically this gave an impetus to colonizing ventures aimed at undercutting the moral and economic foundations of slavery in Africa. Disease proved to be a deadly obstacle to European- and American-born missionaries in tropical Africa, thus spurring projects for enrolling local agents who had acquired childhood immunity. Southern Africa below the Zambezi River attracted missionaries from many parts of Europe and North America because of the absence of the most fearsome diseases. However the turbulent politics of the region complicated their work by restricting their access to organized African kingdoms and chieftaincies. The prevalent mission model until the late 19th century was a station under the direction of a single European family whose religious and educational endeavors were directed at a small number of African residents. Catholic missions acquired new energy following the French Revolution, the old Portuguese system of partnership with the state was displaced by enthusiasm for independent operations under the authority of the Pope in Rome. Several new missionary orders were founded with a particular focus on Africa. Mission publications of the 19th and 20th centuries can convey a misleading impression that the key agents in the spread of African Christianity were foreign-born white males. Not only does this neglect the work of women as wives and teachers, but it diverts attention from the Africans who were everywhere the dominant force in the spread of modern Christianity. By the turn of the 20th century, evangelism had escaped the bounds of mission stations driven by African initiative and the appearance of so-called “faith missions” based on a model of itinerant preaching. African prophets and independent evangelists developed new forms of Christianity. Once dismissed as heretical or syncretic, they gradually came to be recognized as legitimate variants of the sort that have always accompanied the acculturation of religion in new environments. Decolonization caught most foreign mission operations unawares and required major changes, most notably in the recruitment of African clergy to the upper echelons of church hierarchies. By the late 20th century Africans emerged as an independent force in Christian missions, sending agents to other continents.

This book charts the transformation of one of the world's great religions during an age marked by world wars, genocide, nationalism, decolonization, and powerful ideological currents, many of them hostile to Christianity. The book traces how Christianity evolved from a religion defined by the culture and politics of Europe to the expanding polycentric and multicultural faith it is today—one whose growing popular support is strongest in sub-Saharan Africa, Latin America, China, and other parts of Asia. The book sheds critical light on themes of central importance for understanding the global contours of modern Christianity, illustrating each one with contrasting case studies, usually taken from different parts of the world. Unlike other books on world Christianity, this one is not a regional survey or chronological narrative, nor does it focus on theology or ecclesiastical institutions. The book provides a history of Christianity as a popular faith experienced and lived by its adherents, telling a compelling and multifaceted story of Christendom's fortunes in Europe, North America, and across the rest of the globe. It demonstrates how Christianity has had less to fear from the onslaughts of secularism than from the readiness of Christians themselves to accommodate their faith to ideologies that privilege racial identity or radical individualism.

The crossroads of nationalist historiographies in sub-Saharan Africa and of the history of developmentalist attempts that characterise the European late colonial states, have left us with very incomplete images of important trajectories. In the seemingly more “liberal” large colonial empires—notably the French and British—sails were set by 1945 towards a policy of investment and economic change. Some of the scholarly debates question whether this investment was genuine or just a last resort to avoid (rapid) decolonisation; others put the emphasis on inadequate routines of development implemented in these territories, many of which have apparently been continued since decolonisation.In this context, we encounter a clear lack of understanding about how decisions made by individual actors on the administrative level interacted with the larger panorama of social conditions in colonial territories, and of the consequences that these interactions had for the paths towards decolonisation. For a smaller empire such as the Belgian colony of Congo-Léopoldville, these processes are still more obscure; and for the colonies ruled by authoritarian metropoles, as in the cases of territories under Spanish and Portuguese rule, stagnation and absence of change are often taken for granted. In other words, these territories, which were under the rule of metropoles regarded as rather weak in economic terms, are treated as unrepresentative of the broader, European movement towards change in colonial policies. However, the conditions of change towards economic and social modernisation in this latter group of empires, even when inhibited by lack of funding and weak professionalisation of the administration, are frequently very telling for the broader range of challenges that the late colonial states faced.

Gabon, a small oil-rich country straddling the equator on the west coast of Africa, is the wealthiest of France’s former colonies. An early period of colonization in the 19th century resulted in disease, famine, and economic failure. The creation of French Equatorial Africa in 1910 marked the beginning of the sustained lucrative exploitation of Gabon’s natural resources. Gabon began off-shore oil production while still a colony of France. Uranium was also discovered in the last decade of the French Equatorial African empire. Coupled with rich reserves in tropical woods, Gabon has achieved, since independence in 1960, a higher level of export revenue per capita of population than any other country in sub-Saharan Africa in the postcolonial era. However, significant inequality has characterized access to wealth through paid employment throughout the recorded history of monetized labor. While fortunes have been amassed by a minute proportion of the female population of Gabon associated with the ruling regime, and a professional female middle-class has emerged, inequalities of opportunity and reward continue to mark women’s experience of life in this little-known country of West Central Africa. The key challenge facing scholars researching the history of women in Gabon remains the relative lack of historical resources. While significant strides have been made over the past decade, research on women’s history in Francophone Africa published in English or French remains embryonic. French research on African women began to make a mark in the last decade of colonization, notably with the work of Denise Paulme, but then remained a neglected area for decades. The publication in 1994 of Les Africaines by French historian Catherine Coquery-Vidrovitch was hailed at the time as a pioneering work in French historiography. But even this new research contained no analysis of and only a passing reference to women in Gabon.


There are no single-volume studies that address the whole topic of alcohol in Africa or its modern history. Globally, fermented alcohol has a very ancient history, with archaeological findings documenting such drinks many thousands of years ago. Given the relative lack of archaeological work in sub-Saharan Africa, the evidence for the ancient consumption of fermented drinks on the continent is thin, but the earliest records in combination with ethnographic research point to a very long history and to the ubiquity of fermented drinks. Virtually every African society produced one or more kinds of fermented drinks, whether it was palm wine in coastal regions, various wines made from honey or local fruits such as bananas, or, especially, beers produced from millet and sorghum and later maize. In Muslim societies, these fermented drinks, often classified as foods by local peoples, were not seen to violate Qurʾanic prohibition. Ethnographic studies often include detailed accounts of the complex processes through which such drinks were produced and the equally complicated social practices related to drinking. Such drinks were often bought and sold through local trade networks, but fermented drinks are expensive to transport and until the development of modern bottling technology had very short shelf lives. Distillation technology dates only to the 11th century and its spread was closely connected to international trade. During the 20th century, alcohol regulation emerged as a critical element in colonial hegemony, and the importance of alcohol to state revenue persists to the present day. Following independence, with the end of international prohibitions on distilling, industrial brewing and distilling grew rapidly in many African countries, generally led by international enterprises. South African Breweries ultimately emerged as a major international player, with large stakes across the continent. Racist thinking dominated colonial policy on alcohol sales and consumption across much of eastern, central, and southern Africa, and colonial states in those regions used revenue from alcohol monopolies to reinforce racial segregation and domination. This thinking incorporated a racially defined view of collective dependency and abuse which was fueled by colonial expediency and in turn shaped public perceptions and response to African alcohol consumption. Such perspectives have persisted in “expert” discourse in postcolonial Africa. Yet alcohol consumption has been, for men, among the most important leisure activities in many African societies, and in the 20th century, drinking establishments emerged as very important sites of popular culture.

This chapter looks at the history of romantic love in Sub-Saharan Africa. This text comes from a lecture given at the British Academy's 2009 Raleigh Lecture on History. This text attempts to explore some of the methodological and theoretical issues involved in an historical study of love in Africa. It argues that romantic love in Africa is not simply an extension of an imperialist cultural and political project and that emotional regimes cannot be divorced from economic circumstances. It explains that though the configurations of interest and emotion take specific forms in African societies, there is nothing peculiarly African about the evident need of individuals to balance realism and idealism in their emotional lives.

Abstract A long-standing enigma concerns the geographic and ecological origins of the intensively studied vinegar fly, Drosophila melanogaster. This globally distributed human commensal is thought to originate from sub-Saharan Africa, yet until recently, it had never been reported from undisturbed wilderness environments that could reflect its precommensal niche. Here, we document the collection of 288 D. melanogaster individuals from multiple African wilderness areas in Zambia, Zimbabwe, and Namibia. The presence of D. melanogaster in these remote woodland environments is consistent with an ancestral range in southern-central Africa, as opposed to equatorial regions. After sequencing the genomes of 17 wilderness-collected flies collected from Kafue National Park in Zambia, we found reduced genetic diversity relative to town populations, elevated chromosomal inversion frequencies, and strong differences at specific genes including known insecticide targets. Combining these genomes with existing data, we probed the history of this species’ geographic expansion. Demographic estimates indicated that expansion from southern-central Africa began ∼13,000 years ago, with a Saharan crossing soon after, but expansion from the Middle East into Europe did not begin until roughly 1,800 years ago. This improved model of demographic history will provide an important resource for future evolutionary and genomic studies of this key model organism. Our findings add context to the history of D. melanogaster, while opening the door for future studies on the biological basis of adaptation to human environments.

The history of African film began in the 1960s with the independence of the colonies. Despite all kinds of political and economic difficulties, numerous films have been made since then, featuring wide-ranging processes of consolidation, differentiation and transformation which were characteristic of post-colonial sub-Saharan Africa. However, these feature films should not merely be viewed as back references to specifically African problems. The glimmering fictions are imagination spaces. They preserve ideas about how the post-colonial circumstances should be approached. Seen from this perspective, the history of African film may be studied as a history of African utopias.

Frogs of the genus <em>Phrynobatrachus </em>Günther, 1862 are endemic to sub-Saharan Africa. These are increasingly threatened by a number of factors and are believed to be declining. We report on captive breeding experiments involving <em>Phrynobatrachus auritus</em> Boulenger, 1900. We provide a comprehensive life history for this frog with emphasize on tadpole development time, as well as a description of both the advertisement call and calling behaviour of the adult.
