Colonialist arrival in Nigeria is traceable particularly to the_____

1. Analyze the question The question asks what colonial rule in Nigeria can be traced to most directly. "Colonialist arrival" means the point at which Britain began formal control over Nigerian territory.

2. Explain the concept British involvement in Nigeria went through stages:

• Early contact: Explorers, missionaries and traders arrived first. The slave trade came first and was later replaced by "legitimate" trade in palm oil.
• Formal colonization: Britain took political control over Nigerian territory. This began with the annexation of Lagos in 1861 through the Treaty of Cession, signed with King Dosunmu.
• Consolidation: Britain set up the Niger Coast Protectorate, the Protectorates of Northern and Southern Nigeria (1900), and the Amalgamation of 1914.
• Administration: Indirect rule was introduced by Lord Lugard only after colonial control was already established.

3. Step-by-step evaluation of the options

• A. Introduction of Christianity: Missionaries came in the 1840s (e.g., Badagry, 1842). Christianity prepared the ground, but it was not itself the beginning of colonial rule.
• B. Annexation of the Lagos Colony: This was the first formal acquisition of Nigerian territory by Britain, in 1861. It is the start of colonial rule.
• C. Emergence of economic adventurism: Economic motives drove colonialism in general, but this is a broad cause, not a specific event. The question asks for a particular point.
• D. Introduction of indirect rule: This was a system of administration that came after colonization, so it cannot explain the arrival.

4. Answer The question stresses "particularly", which points to a specific event.

Note that option C is a tempting distractor, because economic motives did drive the colonial project. But the question wants the specific starting point, not the general motive.

5. Exam tip Remember the order: Missionaries/traders → Lagos annexation (1861) → Protectorates (1900) → Amalgamation (1914) → Indirect rule. When a question asks when or how colonial rule "began" in Nigeria, think Lagos 1861.
