This is the most difficult sub-page. The Dahomean kingdom was Vodun in its political-spiritual organisation, and Dahomey was a major supplier of captives to European traders. Both facts are documented, and both facts must be held together. We do not flinch from this entanglement; we read it precisely.
The Bight of Benin coast — 1701–1850, the slave-trade economy
The stretch of coastline from the Volta River in the west to Lagos in the east — known to European traders as the ‘Slave Coast’ — was one of the most intense embarkation zones of the Atlantic trade. Between 1701 and 1850, the Trans-Atlantic Slave Trade Database records approximately 1.2 million Africans embarked from this coast, principally through the ports of Ouidah, Aného, Porto-Novo, and Lagos.
Ouidah alone accounted for roughly half of those embarkations during the eighteenth century. The town was a colonial-commercial node where Portuguese, French, English, Dutch and Danish merchants maintained factories alongside the Dahomean royal infrastructure. This is the spatial fact at the heart of this dimension.
Dahomey’s role in supply — military campaigns, market structure
From the conquest of Ouidah in 1727 onward, the Kingdom of Dahomey was the dominant supplier of captives to the European factories at the port. The supply was organised through annual military campaigns against neighbouring polities — the Mahi, the Yoruba kingdoms of Oyo and Ketu, the Egba — and through the redirection of inland trade networks toward the coast.
The Dahomean treasury was substantially funded by the royal monopoly on certain categories of captives and on the duties levied at Ouidah. This is the economic fact: the kingdom and the trade were institutionally interlinked.
Vodun as political-spiritual matrix of the kingdom
At the same time — and inseparably — Dahomey was Vodun in its political-spiritual organisation. The royal lineage held specific Vodun affiliations; the court included ritual offices that were as institutional as the military offices; the calendar of state ceremony was the calendar of the royal Vodun. To remove the religious frame from the political history of Dahomey is to misrepresent it.
This is the difficulty we name openly. The kingdom that produced one of the most sophisticated religious-political architectures of the West African coast was also the kingdom that organised, at its height, the systematic capture and export of human beings. Neither fact erases the other.
Captives, ritual structure, and the question of moral responsibility
The question of moral responsibility is asked, today, by every diaspora visitor who walks the Slave Route at Ouidah and who knows that some of their ancestors departed from that arch. Our editorial position is that the question must be asked, that it must be asked at the historical level (which polities, which networks, which complicities), and that it must be answered without either exculpation or anachronism.
The conditions in which captives were held and shipped — the slave-house, the holding fortress at Ouidah, the violence of the embarkation — are also part of the Vodun history, because the captives carried Vodun knowledge with them across the Atlantic. The diaspora religions are the testimony.
Memory and historiography today — Akinjogbin, Bay, Manning, Soumonni
The modern historiography of Dahomey and the slave trade developed in parallel with African independence. Akinjogbin’s 1967 study (Cambridge) was foundational; Bay’s 1998 reading of the Dahomean court through gender and religious authority (Virginia) opened a new register; Manning’s economic history (Cambridge, 1982) put numbers on the trade and on the kingdom’s share. The Beninese historian Elisée Soumonni, working from the Université d’Abomey-Calavi, has held the Atlantic frame for the past three decades.
This historiography is not closed. Each new generation reads the entanglement again, sometimes from different angles — diaspora-led, gender-focused, archaeological, environmental. The conversation continues.
The Slave Route project at Ouidah — Vodun cosmology and memory inseparable
In 1994, UNESCO launched the international Slave Route project, with Ouidah as one of its earliest signature sites. The Slave Route memorial walk at Ouidah — from the auction square at Place Chacha to the Door of No Return at the beach, with its memorial sculptures by the artists of the Fondation Zinsou — was inaugurated in this frame. In 2017, the project received UNESCO Memory of the World inscription.
The memorial walk is not a museum experience separate from the religious life of the town. The arch, the Forest of Kpassè, the python temple, the lagoon — these are simultaneously historical-memorial sites and active Vodun spaces. The cosmology and the memory are inseparable. This is what we mean when we say Heritage & Routes accompanies the walk; we do not curate it.
