The colonization of Madagascar by Austronesian-speaking people during AD 50–500 represents the most westerly point of the greatest diaspora in prehistory. A range of economically important plants and animals may have accompanied the Austronesians. Domestic chickens ( Gallus gallus ) are found in Madagascar, but it is unclear how they arrived there. Did they accompany the initial Austronesian-speaking populations that reached Madagascar via the Indian Ocean or were they late arrivals with Arabian and African sea-farers? To address this question, we investigated the mitochondrial DNA control region diversity of modern chickens sampled from around the Indian Ocean rim (Southeast Asia, South Asia, the Arabian Peninsula, East Africa and Madagascar). In contrast to the linguistic and human genetic evidence indicating dual African and Southeast Asian ancestry of the Malagasy people, we find that chickens in Madagascar only share a common ancestor with East Africa, which together are genetically closer to South Asian chickens than to those in Southeast Asia. This suggests that the earliest expansion of Austronesian-speaking people across the Indian Ocean did not successfully introduce chickens to Madagascar. Our results further demonstrate the complexity of the translocation history of introduced domesticates in Madagascar.

The history of Islam in East Africa stretches back to around 1000 CE. Until the mid-20th century, it remained largely confined to the coast and closely bound up with the history of the Swahili towns situated on it. The Swahili language remains central to many East African Muslims, hence the occasionally heard phrase, “Swahili Islam.” East African Muslims are mostly Shafiites and some belong to Sufi orders, especially Qadiriyya and Shadhiliyya. Since c. 1850, Islam, with many variations in ritual, has become the religion of speakers of a multitude of languages across the region, second only to Christianity. The region’s independent nation-states initially promised equality for all religions within a secular order. Since c. 1990, though, the minority status of East African Muslims has fed into a multitude of grievances related to the region’s economic and political impasses. This situation has led to growing movements of Islamic preaching and activism, supported by increased contacts with congregations elsewhere in the Indian Ocean. At times, they have influenced electoral politics, especially in Zanzibar, where Islamic activism resonates with fear of marginalization by the mainland. In Kenya, Somali-influenced Islamist terrorists committed a series of atrocities in the 2010s. East African governments, in turn, have been proactive in tracking and disrupting such networks, and in Kenya, the government engaged in targeted assassination. Nevertheless, peaceful coexistence between Muslims and adherents of other religions remains the norm in East Africa, and its dynamics are often poorly understood.

Australian deserts remain dotted with the ruins of old mosques. Beginning with a Bengali poetry collection discovered in a nineteenth-century mosque in the town of Broken Hill, Samia Khatun weaves together the stories of various peoples colonized by the British Empire to chart a history of South Asian diaspora. Australia has long been an outpost of Anglo empires in the Indian Ocean world, today the site of military infrastructure central to the surveillance of 'Muslim-majority' countries across the region. Imperial knowledges from Australian territories contribute significantly to the Islamic-Western binary of the post- Cold War era. In narrating a history of Indian Ocean connections from the perspectives of those colonized by the British, Khatun highlights alternative contexts against which to consider accounts of non-white people. Australianama challenges a central idea that powerfully shapes history books across the Anglophone world: the colonial myth that European knowledge traditions are superior to the epistemologies of the colonized. Arguing that Aboriginal and South Asian language sources are keys to the vast, complex libraries that belie colonized geographies, Khatun shows that stories in colonized tongues can transform the very ground from which we view past, present and future.

The Impact

Timing and magnitude of surface uplift are key to understanding the impact of crustal deformation and topographic growth on atmospheric circulation, environmental conditions, and surface processes. Uplift of the East African Plateau is linked to mantle processes, but paleoaltimetry data are too scarce to constrain plateau evolution and subsequent vertical motions associated with rifting. Here, we assess the paleotopographic implications of a beaked whale fossil (Ziphiidae) from the Turkana region of Kenya found 740 km inland from the present-day coastline of the Indian Ocean at an elevation of 620 m. The specimen is ∼17 My old and represents the oldest derived beaked whale known, consistent with molecular estimates of the emergence of modern strap-toothed whales (Mesoplodon). The whale traveled from the Indian Ocean inland along an eastward-directed drainage system controlled by the Cretaceous Anza Graben and was stranded slightly above sea level. Surface uplift from near sea level coincides with paleoclimatic change from a humid environment to highly variable and much drier conditions, which altered biotic communities and drove evolution in east Africa, including that of primates.

ABSTRACTThis article examines the history of two Indian newspapers, Tanganyika Opinion and Tanganyika Herald, to demonstrate how business considerations provided both the opportunity for East African Indians to make public arguments and the central limitation on the arguments that could be made. Founded on the inspiration of mass nationalist action through a territorial hartal, the Tanganyika Opinion and later the Herald blazed the trails that articulated ‘Greater India’ among the Anglo-Gujarati reading public in Tanganyika. But growing conservative sentiments within this vulnerable minority, along with rising sectarian division, reduced both the patronage and audience for a singular ‘anti-colonial’ politics by the 1930s and 1940s. Moreover, as a marginal print node along the Indian Ocean littoral, the Opinion and Herald came to rely on an opportunistic mixture of wire services and consular propaganda to keep abreast of regional and international news developments. Ultimately, the shrinking market for Anglo-Gujarati newspapers and rising opportunities in Swahili-language journals had sealed the doom of these and similar Indian newspapers by the time ‘African’ political independence arrived in the early 1960s.

Abstract El Niño–Southern Oscillation (ENSO) has large socioeconomic impacts worldwide. The positive phase of ENSO, El Niño, has been linked to intense rainfall over East Africa during the short rains season (October–December). However, we show here that during the extremely strong 2015 El Niño the precipitation anomaly over most of East Africa during the short rains season was less intense than experienced during previous El Niños, linked to less intense easterlies over the Indian Ocean. This moderate impact was not indicated by reforecasts from the ECMWF operational seasonal forecasting system, SEAS5, which instead forecast large probabilities of an extreme wet signal, with stronger easterly anomalies over the surface of the Indian Ocean and a colder eastern Indian Ocean/western Pacific than was observed. To confirm the relationship of the eastern Indian Ocean to East African rainfall in the forecast for 2015, atmospheric relaxation experiments are carried out that constrain the east Indian Ocean lower troposphere to reanalysis. By doing so the strong wet forecast signal is reduced. These results raise the possibility that link between ENSO and Indian Ocean dipole events is too strong in the ECMWF dynamical seasonal forecast system and that model predictions for the East African short rains rainfall during strong El Niño events may have a bias toward high probabilities of wet conditions.

The largest documented outbreak of Chikungunya virus (CHIKV) disease occurred in the Indian Ocean islands and India during 2004–2007. The magnitude of this outbreak led to speculation that a new variant of the virus had emerged that was either more virulent or more easily transmitted by mosquito vectors. To study this assertion, it is important to know the origin of the virus and how the particular strain circulating during the outbreak is related to other known strains. This study genetically characterized isolates of CHIKV obtained from Mombasa and Lamu Island, Kenya, during 2004, as well as strains from the 2005 outbreak recorded in Comoros. The results of these analyses demonstrated that the virus responsible for the epidemic that spread through the Indian Ocean originated in coastal Kenya during 2004 and that the closest known ancestors are members of the Central/East African clade. Genetic elements that may be responsible for the scope of the outbreak were also identified.

While the use of Chinese porcelain dishes in the stone towns along the Swahili coast has recently found much attention in art historical scholarship regarding the eighteenth to early twentieth centuries, the pre-history of these dynamics in the medieval period has up to now only been fully considered in other fields such as archaeology and anthropology. This paper sheds new light on the interrelations between the built environment and material culture in coastal East Africa from an art historical perspective, focusing on premodern Indian Ocean trajectories, the role of Chinese porcelain bowls that were immured into Swahili coral stone buildings, and on architecture across boundaries in a medieval world characterized by far-reaching transcultural entanglements and connectivity. It will show how Chinese porcelain bowls in premodern Swahili architecture linked the stone towns along the coast with other sites both inland and across the Indian Ocean and beyond, and how these dynamics were shaped by complex intersections between short-distance and long-distance-relationships and negotiations between the local and the global along the Swahili coast and beyond.

Today the Malay language is known to have communities of speakers outside the Malay archipelago, such as in Australia inclusive of the Christmas Islands and the Cocos (Keeling) Islands in the Indian Ocean (Asmah, 2008), the Holy Land of Mecca and Medina (Asmah et al. 2015), England, the Netherlands, France, and Germany. The Malay language is also known to have its presence on the Asian mainland, i.e. Thailand, Cambodia, and Vietnam. As Malays in these three countries belong to a minority, in fact among the smallest of the minorities, questions that arise are those that pertain to: (i) their history of settlement in the localities where they are now; (ii) the position of Malay in the context of the language policy of their country; and (iii) maintenance and shift of the ancestral and adopted languages.

ABSTRACTThis essay considers the role of Hindi films in urban Tanzania in writing new chronologies of Indian Ocean world history. Examining films and movie theatres through overlapping local, national and transnational lenses, the article contributes to our understandings of the encounter between the Indian diaspora and nationalism in East Africa, and extends the history of Indian Ocean world connections into the second half of the twentieth century. In order to escape the historiographical dialectic between nation and diaspora which splits scholarship on Hindi films overseas, cinema needs to be denationalized, and everyday social histories of urban cinema halls can then be framed within the Indian Ocean world. To do so successfully, however, we must challenge scholarship which asserts the collapse of this world in the early modern or colonial period (at the latest), in order to extend an Indian Ocean scale to capture the vibrant twentieth-century creation of a regional popular culture. The history of Bombay films in urban Tanzania thus enables a viewing of the transnational production of culture, and the ways in which cross-cultural flows are part of the construction of important categories like race and nationalism across the history of East Africa.

Indo-African trade relations are one of the imperative segments to understand African settlements in different parts of Indian sub-continent. Several Africans rose to positions of authority as generals and governors, in the Janjira and Sachin kingdoms they rose from king-makers to Emperors. The evidence of African trade in India has a significant history. From ancient times, three valuable export commodities which were prized in Africa: pepper, silk and cotton. The migration from the African sub-continent into India went up only in the sixth century A.D. but we have had an incredible trade-relation from time immemorial. From the Sixth century through the fifteenth century the history of the East African coast is somewhat illuminated by Arabs, Persians and Europeans. During the course of the sixteenth century the Portuguese dominated the Indian Ocean and its shoreline. Portugal was determined to remove Muslim merchants, especially Arabs, in the Indian Ocean system. This paper tries to explore India Africa relation especially with east Africa from earliest times to nineteenth century A.D. The paper recognizes the fact that trade and natural resources have been the principal reason   behind the age-old links between Africa and India. The paper identifies the Cultural assimilation and African diaspora through the ages which has a vital facet to further strengthen the Trade Relations.
