Mainstream economic anthropologists, archaeologists, and historians define the Swahili coast as a dynamic zone of connections and a gateway to globalization. This understanding has been based on studies drawing on archaeological, documentary, and historical accounts from the elite people of several large medieval cities: Kilwa; Mombasa; Lamu; and, later, Zanzibar. These cities had deep harbors that allowed them to develop into large centers of trade, attracting and hosting merchants from the wider Indian Ocean. Academics have primarily viewed the Swahili elite as brokers who forged social and economic networks with inland communities of foragers, herders, and farmers for the provision of trade items: food to sustain the urban populations and ivory, destined for export. These inland communities were small and culturally distinct, pursuing divergent subsistence strategies. Their role in the making of the Swahili world has not been fully appreciated. Although they did not fit neatly into the rubric of global trade and brokerage, scholarship has viewed their integration into Indian Ocean commerce as inevitable.

Inland from Mombasa, a book that arose from Bresnahan’s doctoral research, is inspired by studies that have increasingly deviated from Fernand Braudel’s foundational study of the Mediterranean.Footnote ¹ Braudelian approaches – viewing the Indian Ocean as a unifying economic system – have failed to see the “specificity and diversity of local circumstances in the different societies living along the ocean shores” (p. 14). In contrast, Bresnahan integrates historical linguistics, archival material, and oral traditions to reconstruct a millennial history of the Mijikenda-speaking peoples of the Kenyan coast.Footnote ² His research reveals that, throughout much of the period, Mijikenda-speaking inland societies maintained limited engagement with oceanic trade, urban cosmopolitanism, and empires. He reframes the Swahili coast as a dynamic zone of asymmetrical connections instead of seeing it as a straightforward gateway to globalization. Inland communities were active agents who sometimes embraced and sometimes resisted coastal cosmopolitanism and empire. Their relationship with the coast – with whom they forged social and economic networks – was not guaranteed. In many ways, it was hinterland communities that shaped and constrained oceanic exchange and social meaning.

Organized into five compact and tightly argued chapters, Inland from Mombasa reconstructs the deep history of Mijikenda-speaking societies over the past two millennia, showing how profoundly they influenced global trade, even as they rejected many of the cosmopolitan practices that historians have often claimed to be critical to creating global connections. Bresnahan shows that the Mijikenda intentionally chose to dwell in smaller communities over urbanism, preferred local religion guided by ritual practices over conversion to Islam, and favored inland trade over maritime commerce. Through a mixed-methods approach, he interrogates the corpus of complementary evidence that strongly supports the notion that the inland communities did not simply drift into the Indian Ocean world but made deliberate decisions about their orientation. They had agency to choose to engage, resist, or adopt partial linkages. They had deliberately cultivated the art of belonging and resistance.Footnote ³ These findings contradict previous studies that have centered on the big port cities, cosmopolitanism, and Islamization as the primary drivers of membership into the Indian Ocean world.Footnote ⁴

In Chapter One, “Unmoored from the Ocean”, Bresnahan argues that being “unmoored” from the sea did not mean marginalization. He traces the shifts in trade routes, power relations, and ecological dynamics that caused inland producers to disengage from direct maritime exchange. He finds that inland communities developed alternate forms of trade and cultural connection that still anchored them in the Indian Ocean world.

Chapter Two, “Looking Inland, to the World”, rejects traditionalist ways of seeing inland groups as passive coastal backwaters and instead shows how they actively engaged in global commerce while passionately maintaining their independence. The Mijikenda communities engaged in caravan trade, regional exchange of forest products (ivory, timber, honey), and built diplomatic ties based on blood-brother alliances and other treaties.Footnote ⁵ Where other studies have favored assimilation, Bresnahan finds that the Mijikenda engaged with their Swahili Arab partners, while remaining culturally distinct from them.Footnote ⁶ The Mijikenda here provide fertile data for thinking about “alternative forms of connectedness”– small-scale, dispersed, and ritual-embedded – that plugged inland societies into the wider Indian Ocean economy.

In Chapter Three, “The Inland Underpinnings of Indian Ocean Commerce”, Bresnahan documents the concrete ways inland societies provided essential resources and labor for Indian Ocean commerce: forest products; agricultural surpluses; human labor (porters/caravans); and regional origin points for trade routes linking the coast to the interior. He employs linguistic and archaeological evidence to map how inland crafts, metallurgy, and production systems supported coastal trade. He argues that coastal maritime prosperity would not have been possible without these inland underpinnings. In effect, the hinterland was the foundation of – not peripheral to – the prosperity that the coastal urban areas enjoyed and have erroneously been credited with.

Chapter Four, “Inland Villages and Oceanic Empires” focuses on the interface of inland communities with the then-emerging coastal and Indian Ocean empires (Portuguese, Omani, and, later, British). He shows how inland places became theaters of negotiation, resistance, and adaptation as each empire extended from the sea into the interior. The case studies of Mijikenda polity reforms, slave-raid dynamics, and shifting alliances illustrate how inland societies reshaped (rather than simply succumbed to) the expansion of maritime empires. In Chapter Five, “From Mijikenda City to Busaidi Backwater”, Bresnahan discusses the transition of one inland site from a regional center of power to its incorporation into the nineteenth-century Busaidi/Zanzibari system. He details how inland trade and ritual networks were gradually subordinated, but not erased, by the expanding coastal empire. This chapter underscores how the fate of inland societies had direct implications for the fortunes of the coastal port – showing a two-way dynamic rather than one-way dominance. As inland communities’ power declined, so did coastal cities. All but a few were abandoned and today are in ruins.

In the concluding chapter, Bresnahan proposes that a complete story of Indian Ocean East Africa must include inland societies as active agents rather than passive hinterlands. The inland’s non-urban, ritual-rich, forest-based economy was vital to the globalized Indian Ocean system. Reflecting on the implications of this for historical scholarship, especially regarding traditional center–periphery models, and on its contemporary relevance for Kenyan society and heritage, he concludes:

Their positionality as inland producers and conveyors of subsistence, export goods, and labor made them indispensable to the larger urban political economy. To many, economic interdependences were desirable, but some forms of political assimilation or cosmopolitan identity, including intermarriage, were by choice. Consequently, most Mijikenda communities maintained and jealously guarded their local political forms and identities as they selectively adopted coastal items and practices.

I found Inland from Mombasa a long-overdue book. Carefully researched, imaginatively integrated, and elegantly written, this book reminds us that continuing to privilege coastal towns as centers of power and cosmopolitanism fails to address all sources of economic power in Swahili civilization. The systematic integration of linguistics, oral traditions, and a fresh rereading of the archives reframes the argument: it re-centers the people of the hinterland, without whose cooperation townsfolk would have found it difficult to accumulate wealth and sustain their cosmopolitanism. That said, while I found the tight focus around Mombasa and nearby inland useful, some readers may miss the inclusion of other Swahili centers, such as Lamu, Malindi, Kilwa, and Zanzibar. Overall, many audiences – including scholars and students of East African history, Swahili studies, and Indian Ocean history – historical linguists, and anthropologists interested in mobility, exchange, and political economy, as well as those teaching precolonial/early modern Indian Ocean worlds will find Inland from Mombasa an indispensable counterpoint to port-centered narratives.
