The annexation of Lagos as a British Crown Colony in 1861 marked a defining moment in Nigeria’s colonial evolution. By the mid-nineteenth century, Lagos had developed into a thriving coastal city-state and an essential node in regional and trans-Atlantic trade. Prior to colonisation, it was ruled by Yoruba monarchs whose authority rested on complex alliances with hinterland kingdoms and coastal merchants. Its strategic position along the Gulf of Guinea made it a crucial link in the Atlantic economy, first as a centre of the slave trade and later as a site of emerging “legitimate commerce.”
Britain’s growing interest in Lagos was motivated by its economic potential, missionary activity, and the drive to suppress the trans-Atlantic slave trade following its abolition in 1807. The formal establishment of Lagos as a Crown Colony on 6 August 1861 marked the start of sustained British territorial and administrative expansion into what would later become Nigeria.
Key Events and Figures Leading to Annexation
In the early nineteenth century, Lagos was under the rule of King Kosoko, who came to power in 1845 after deposing Oba Akitoye. Kosoko’s reign coincided with rising British influence along the West African coast through merchants, missionaries, and naval patrols enforcing anti-slavery treaties. While Kosoko maintained traditional trade networks, including participation in the slave trade, Akitoye sought British assistance to regain his throne.
In December 1851, the British launched the Bombardment of Lagos, a decisive military intervention that ousted Kosoko and reinstated Akitoye. The following year, Akitoye signed a Treaty of Abolition (1852) with Britain, committing Lagos to end its involvement in the slave trade and promote “legitimate commerce.”

After Akitoye’s death in 1853, his son Oba Dosunmu (Docemo) ascended the throne. British officials, led by Consul Benjamin Campbell, began pressing for formal annexation, arguing that instability in Lagos threatened British commercial interests. On 6 August 1861, under the presence of the British warship HMS Prometheus, Dosunmu reluctantly signed the Treaty of Cession, transferring sovereignty of Lagos and its territories to Queen Victoria.
The treaty offered the Oba and his chiefs a modest annual pension but effectively brought Lagos under British control. From that moment, Lagos became Britain’s first permanent foothold on the Nigerian coast, paving the way for the consolidation of colonial rule across the region.
Economic and Social Transformations
The creation of the Crown Colony triggered significant economic and social restructuring. British administrators quickly moved to reorganise trade, establish new governance systems, and suppress all remnants of slavery. Lagos was reoriented towards export-based “legitimate commerce” in palm oil, ivory, hides, and agricultural produce.
European trading firms such as John Holt & Co., Elder Dempster Lines, and Patterson Zochonis (PZ) established commercial bases in the city. Customs regulations, port improvements, and secure trade routes encouraged the steady inflow of British goods and capital.
The abolition of slavery disrupted local hierarchies and trade practices. Many former slave traders adapted to new economic realities by engaging in palm produce and other exports. At the same time, thousands of freed Africans, known as Saros or Recaptives, migrated to Lagos from Sierra Leone and elsewhere. Educated and Christian, they became influential merchants, civil servants, and educators who helped shape the colony’s emerging middle class.
British rule also accelerated urbanisation. Missionaries, especially from the Church Missionary Society (CMS), established schools and churches such as St. Paul’s Church and CMS Grammar School (founded 1859). These institutions promoted Western education, literacy, and Christianity. However, social change was uneven: while the Western-educated elite benefited from new opportunities, traditional rulers and indigenous systems of governance were weakened. Land tenure reforms, taxation, and legal ordinances frequently favoured European and elite African interests over communal rights.
Colonial Influence and Governance
After annexation, Lagos came under direct rule from London, with Henry Stanhope Freeman appointed as its first Governor (1862–1865). The colonial administration introduced British-style governance and law, marking the beginning of a bureaucratic state structure.
In 1863, the Supreme Court of Lagos was established, symbolising the imposition of British legal norms over customary practices. Policing, public health, and sanitation services were gradually developed, while new ordinances sought to regulate trade and public behaviour.
By 1865, the Lagos Town Council had been inaugurated, serving as an early experiment in municipal administration. British officials viewed Lagos as a strategic base for extending influence into the Yoruba hinterland, often combining diplomacy, missionary activity, and military expeditions. Treaties signed with neighbouring communities facilitated British penetration into the interior, culminating in the formation of the Colony and Protectorate of Southern Nigeria (1906) and later the Colony and Protectorate of Nigeria (1914).
Economic Integration and Urban Development
From the 1870s onwards, Lagos evolved into a major export port for Britain’s industrial economy. The global demand for palm oil and, later, palm kernels stimulated commercial growth. The port became a magnet for African and European entrepreneurs, transforming Lagos into a cosmopolitan urban centre.
The late nineteenth century saw major infrastructure projects: the construction of new quays, the introduction of steamships, and the establishment of telegraphic communication. The most transformative development was the Lagos Railway (completed in 1898), linking Lagos to Ibadan and other hinterland markets. This integration of the hinterland economy with the Atlantic trade network marked the full incorporation of Lagos into Britain’s colonial economic system.
Ethnically, Lagos became a vibrant mosaic of Yoruba, Hausa, Igbo, Saro, Brazilian returnees (Agudas), and Europeans. Each community contributed to the city’s social and economic dynamism. However, colonial urban planning reinforced class divisions, separating European quarters from African settlements and introducing property laws that marginalised traditional landowners.
Legacy and Contemporary Significance
The 1861 annexation of Lagos had far-reaching consequences for Nigeria’s political and economic history. As the first British possession in modern Nigeria, Lagos became the administrative and commercial nucleus from which colonial expansion radiated. Its early exposure to Western education and governance created a politically conscious African elite who would later spearhead nationalist movements.
In the twentieth century, figures such as Herbert Macaulay, Nnamdi Azikiwe, and Obafemi Awolowo traced their political and intellectual roots to colonial Lagos’s institutions and cosmopolitan environment.
Economically, Lagos retained its centrality long after independence. It continues to function as Nigeria’s commercial capital and gateway to global trade. The port, financial institutions, and diverse population reflect the enduring legacies of colonial infrastructure and commerce.
Yet, the colonial era also bequeathed deep structural challenges, urban overcrowding, class inequality, and land disputes rooted in nineteenth-century policies. The erosion of indigenous governance and the imposition of foreign systems left complex legacies still visible in Nigeria’s modern political framework.
Conclusion
The transformation of Lagos into a British Crown Colony in 1861 marked the beginning of formal colonial rule in Nigeria. What began as an effort to suppress slavery and secure trade routes evolved into a comprehensive reorganisation of political authority, economy, and society.
Lagos’s journey from a Yoruba coastal kingdom to a British administrative hub symbolises the intersection of African resilience and imperial ambition. The developments that followed, trade reform, infrastructural modernisation, and sociocultural change, laid the groundwork for Nigeria’s eventual formation as a unified colonial state.
Today, Lagos stands both as a monument to colonial encounters and as a dynamic centre of African modernity, its history embodying the complexities of colonialism’s enduring influence on Nigerian identity.

Author’s Note
This article analyses the historical transformation of Lagos from an independent coastal kingdom into the first British Crown Colony in modern Nigeria. It highlights the political negotiations, economic transitions, and social changes that followed annexation in 1861. The legacy of this transformation remains visible in Lagos’s role as Nigeria’s commercial and cultural epicentre.
