We report on recent findings of a fruitful research agenda that explores the importance of ethnic-specific traits in shaping African development. First, using recent surveys from Sub-Saharan African countries, we document that individuals identify with their ethnic group as often as with the nation pointing to the salience of ethnicity. Second, we focus on the various historical and contemporary functions of tribal leaders (chiefs) and illustrate their influence on various aspects of the economy and the polity. Third, we elaborate on a prominent dimension of ethnicity, that of the degree of complexity of pre-colonial political organization. Building on insights from the African historiography, we review recent works showing a strong association between pre-colonial centralization and contemporary comparative development both across and within countries. We also document that the link between pre-colonial political centralization and regional development -as captured by satellite images of light density at night-is particularly strong in areas outside the vicinity of the capitals, where due to population mixing and the salience of national institutions ethnic traits play a lesser role. Overall, our evidence is supportive to theories and narratives on the presence of a "dual" economic and institutional environment in Africa.

We examine the effect of malaria on economic development in Africa over the very long run. Using data on the prevalence of the mutation that causes sickle cell disease, we measure the impact of malaria on mortality in Africa prior to the period in which formal data were collected. Our estimate is that in the more afflicted regions, malaria lowered the probability of surviving to adulthood by about ten percentage points, which is twice the current burden of the disease. The reduction in malaria mortality has been roughly equal to the reduction in other causes of mortality. We then ask whether the estimated burden of malaria had an effect on economic development in the period before European contact. Using data at the ethnic group level, we find little evidence of a negative relationship between malaria burden and population density or other measures of development.

In the second half of the seventeenth century, Italian Capuchin missionaries who traveled to West Central Africa both colluded in and critiqued Portuguese slave trading practices. Drawing from their experience on slave galleys in the Mediterranean and their medieval Franciscan heritage, Capuchins brought earlier concepts governing enslavement to bear in Central Africa. Examining Capuchin interventions in exchanges of goods and slaves, their declamations against Portuguese warmongering, their efforts to free unjustly enslaved Africans, and the ways in which they sought to prohibit slave sales to Protestants, this article positions this group of religious agents as important mediators of struggles for empire between the Portuguese, Dutch, British, French, and Spanish in precolonial coastal Africa and as protagonists in their own right. On the basis of the Capuchins’ critique of economic gain and the Kongolese embrace of Catholicism, Capuchins crafted a counter discourse that, if only partially successful, challenged emerging models of Atlantic enslavement.

Abstract Recent research points to a renewed scholarly interest in the West African Middle Ages and the Sahelian imperial tradition. However, in these works only tangential attention is paid to the role of Muslims, and especially to clerical communities. This essay tackles theoretical and historiographical insights on the role of African Muslims in the era of the medieval empires and argues that the study of Islam in this region during the Middle Ages still suffers from undertheorizing. On the contrary, by using a ‘discursive approach’ scholars can unravel access to fascinating aspects of the history of West African Muslims and in particular to the crucial role played by clerical communities, who represented one node of the web of diffused authority which is characteristic of precolonial West African social and political structures.
