British colonialism left a deep and complex legacy in Nigeria, influencing its political structures, economic development, social systems, and cultural identity. Here are some of the most notable legacies:

1. Political Structures and Governance

• Introduction of Centralized Governance: British colonial authorities replaced Nigeria's diverse pre-colonial political systems (kingdoms, emirates, chiefdoms) with a centralized, bureaucratic government. This created a legacy of strong central authority, setting the stage for Nigeria’s modern federal system.
• Indirect Rule: The British used "indirect rule," particularly in the north, where they governed through existing traditional leaders. This system preserved pre-colonial hierarchies in the north but imposed new leaders in some parts of the south, disrupting local governance structures. Indirect rule contributed to ethnic divisions and mistrust in governance, which persist to this day.
• Foundation of Ethnic and Regional Tensions: The British demarcated Nigeria’s borders without regard to ethnic, linguistic, or religious divisions, grouping over 250 ethnic groups into a single colony. The policy of dividing Nigeria into northern, western, and eastern regions (dominated by the Hausa-Fulani, Yoruba, and Igbo respectively) fostered regionalism and ethnic competition for political power, laying the groundwork for post-independence tensions and civil conflict, including the Biafran War.

2. Economic Legacy

• Resource Extraction Economy: British colonialism reoriented Nigeria’s economy towards exporting raw materials, such as palm oil, cocoa, rubber, and, later, oil. Colonial policies discouraged industrial development, creating an economy dependent on exporting raw resources and importing manufactured goods. This structure left Nigeria vulnerable to fluctuations in global commodity prices, which continues to impact its economy.
• Oil Dependency: While oil became a significant factor after independence, British colonial infrastructure projects and governance set the stage for an economy centered on resource extraction. British companies, notably Shell, were deeply involved in Nigeria's oil sector, establishing a precedent for foreign influence and dominance in Nigerian oil, which has had long-term social and environmental impacts, especially in the Niger Delta.
• Land Ownership and Labor Policies: The British introduced a system of land tenure laws that undermined communal landholding systems, particularly in the south, allowing the colonial state to control land for resource extraction. Labor policies during colonialism created an urban working class and reshaped traditional labor practices, contributing to the development of labor unions and a growing awareness of workers' rights in the post-independence period.

3. Social and Cultural Impact

• Educational System and Language: The British established English as the official language and introduced Western education, which became a marker of social mobility. English continues to be Nigeria’s lingua franca, used in government, education, and business, but it also created a divide between the educated elite and those without access to colonial schooling. Western education also helped form a Western-educated political elite who became Nigeria's post-colonial leaders.
• Christianity and Religious Division: Missionaries, mainly in the south, spread Christianity, leading to a divide between the predominantly Muslim north and largely Christian south. This religious split has contributed to Nigeria's socio-political tensions, sometimes fostering conflicts that are intertwined with ethnic and regional divides.
• Erosion of Indigenous Culture: British colonialism promoted Western norms as superior to Nigerian customs, leading to the erosion of indigenous languages, religions, and cultural practices. While Nigerian culture remains vibrant and diverse, the colonial legacy still affects perceptions of tradition versus modernity and influences education, law, and social norms.

4. Legal and Judicial Systems

• British Common Law System: Nigeria inherited the British common law system, which continues to serve as the foundation of its legal system. This legacy is particularly strong in civil and criminal law, while customary law coexists for personal matters such as marriage and inheritance, creating a complex dual legal system.
• Dual Legal System: The British colonial administration retained Islamic law (Sharia) in the north, creating a dual legal system that persists. Post-independence, this has led to debates over the place of Sharia within Nigeria's legal system and has fueled regional tensions over the role of religion in governance.

5. Infrastructural Development and Urbanization

• Railways and Ports: The British developed railways, ports, and roads primarily to facilitate the export of resources rather than to integrate Nigeria’s regions or promote balanced development. This infrastructure was concentrated in resource-rich areas, such as the south, creating uneven development that remains evident in Nigeria’s regional inequalities today.
• Urbanization and Development of Lagos: Lagos, initially a British colonial hub, became Nigeria’s most populous and economically important city. The urbanization policies started during colonial rule led to rapid population growth in major cities without adequate infrastructure, a challenge Nigeria continues to face.

6. Formation of National Identity and Independence Movements

• Rise of Nationalism: British colonial rule sparked nationalist sentiments, leading to the growth of independence movements among the Western-educated elite and workers. Nationalist leaders like Nnamdi Azikiwe, Obafemi Awolowo, and Ahmadu Bello used Western education and political exposure to mobilize for independence. However, the colonial “divide and rule” policies and regional inequalities complicated efforts to forge a unified national identity.
• Ethnic-based Politics: Regional favoritism during colonial rule influenced political affiliations along ethnic lines, a trend that continues to shape Nigerian politics. Independence in 1960 did not erase these divisions but instead brought them to the fore, complicating Nigeria’s efforts to establish stable democratic governance.

Summary

The legacy of British colonialism in Nigeria is characterized by enduring political, economic, social, and cultural influences. While it provided structures like centralized governance, legal systems, and transportation infrastructure, it also left Nigeria with challenges: ethnic and regional divisions, economic dependency on raw materials, and a dual legal system that often reflects deeper social and religious divides. These colonial legacies continue to shape Nigeria’s national identity, economic strategies, and political struggles, influencing the country’s development trajectory to this day.
