Lagos began with water. Long before modern streets and skylines, the island and creeks at the edge of the lagoon system offered fish, canoe routes, and sheltered passage between the interior and the sea. These waterways shaped daily life, movement, and exchange, and they quietly prepared the ground for a city whose importance would one day extend far beyond its shores.
Archaeological and historical scholarship describes Lagos Island as home to Yoruba speaking fishing and hunting communities by the late fifteenth century. Local traditions associate early settlement with Awori Yoruba groups, whose presence remains central to cultural memory in the region. Life revolved around fishing, salt making, canoe transport, and small scale trade, activities well suited to a lagoon environment where water was the easiest path between communities.
Awori memory and the early lagoon economy
In its earliest phase, Lagos was not a capital or an empire. It was a working settlement sustained by the lagoon. Canoes connected villages, carried produce, and linked coastal communities to inland markets. These routes made Lagos a natural meeting point, a place where goods and people could pass through without crossing open ocean or dense forest.
Over time, this watery crossroads increased Lagos’s value. What began as subsistence activity gradually supported wider exchange networks. Control of lagoon movement became a source of influence, setting the stage for political transformation.

Eko under Benin authority
By the late sixteenth century, Lagos entered a new political order. The Kingdom of Benin extended its authority westward and established influence over the settlement, which it called Eko. Lagos did not lose its local leadership, but it became tied to a larger imperial system that shaped succession, tribute, and external relations.
Benin’s involvement mattered deeply. It linked Lagos to established structures of power and positioned it within regional trade networks that connected inland states to the coast. Lagos became a coastal outpost with strategic value, capable of controlling access between the lagoon corridor and Atlantic exchange.
Atlantic trade and the shift toward the Slave Coast
European contact along the Bight of Benin began in the fifteenth century, but Lagos did not immediately emerge as a major port. Trade patterns along the coast shifted repeatedly as markets, rivalries, and regional conflicts changed. The decisive moment came much later, in the second half of the eighteenth century.
Research on coastal and lagoon traffic shows that Lagos rose sharply in importance toward the end of the eighteenth century, as conflicts and instability disrupted older slave trading ports further west. Captives were increasingly diverted eastward along lagoon routes, and Lagos became a principal point of export. The lagoon system allowed enslaved people to be transported efficiently from inland regions to coastal embarkation points, often beyond the reach of rival powers.
Lagos as a major Slave Coast port
By the late eighteenth century, Lagos had become one of the most important ports on the eastern Slave Coast. This transformation reshaped the settlement’s economy and politics. Warfare, raiding, judicial enslavement, and coercive social systems supplied captives for export. Control of routes and markets strengthened ruling elites and merchant networks, while access to European goods and firearms altered regional power balances.
The prosperity of Lagos during this period rested on human suffering. Families were torn apart, communities destabilised, and violence embedded in economic life. The port’s rise cannot be separated from the Atlantic system that treated people as cargo.
British intervention and the 1851 bombardment
By the nineteenth century, Britain sought to suppress the Atlantic slave trade through naval patrols and coercive diplomacy. Lagos became a target because of its continued role in export slaving and its political leadership.
In December 1851, British naval forces attacked Lagos in an operation often called the Bombardment of Lagos. The assault aimed to remove Oba Kosoko, who resisted British demands to abandon the export trade, and to install Akitoye, a rival claimant willing to cooperate. Kosoko was forced out, and British influence over Lagos’s leadership intensified.
The 1 January 1852 treaty
Military force was followed by formal agreement. On 1 January 1852, a treaty was concluded between British representatives and the King and chiefs of Lagos. Its central provision declared that the export of enslaved people to foreign countries was abolished within Lagos territory. Local authorities agreed to enforce this prohibition and punish violations.
The treaty altered Lagos’s position in the Atlantic world. While systems of dependency and coerced labour did not disappear overnight, the agreement curtailed Lagos’s role in international slave export and increased British control over the port’s external relations.
From influence to annexation, the 1861 cession
British involvement deepened over the next decade. In August 1861, Oba Dosunmu signed the Treaty of Cession, transferring sovereignty over Lagos to Britain. Contemporary records describe the negotiations as taking place under threat of military action, leaving little room for refusal.
With the cession, Lagos became a British possession. Colonial administration expanded rapidly, and British law became the framework for governance. The Oba retained a title and limited authority, but real power shifted to colonial officials.
Returnees and a changing city
The nineteenth century also brought new populations. Liberated Africans from Sierra Leone, often known as Saro, and Afro Brazilian returnees settled in Lagos. These communities became influential in trade, education, religion, and architecture, shaping neighbourhoods, institutions, and cultural life.
Their presence added new layers to Lagos’s identity. Indigenous lineages, regional migrants, and Atlantic returnees negotiated space and status in a city shaped by both forced movement and determined return.

A city forged by water and power
The history of Lagos is not a single origin story but a sequence of transformations. A lagoon settlement became Eko under Benin authority, rose as a major Slave Coast port in the late eighteenth century, faced British naval force in 1851, entered a treaty regime in 1852, and was absorbed into the British Empire in 1861. Alongside conquest and coercion, migration and adaptation shaped the city’s character.
Modern Lagos stands on foundations laid by water routes, political ambition, commercial power, and the long shadow of enslavement.
Author’s Note
Lagos was shaped by movement. The lagoon sustained early Yoruba communities, carried the authority of Benin into Eko, and later moved captives toward the Atlantic world. British warships and treaties redirected that movement, pushing Lagos into colonial rule. Yet returnees from across the Atlantic also flowed back into the city, adding enterprise, culture, and resilience. Lagos emerged from these currents as a city defined not by one origin, but by centuries of power, loss, and reinvention.
