Concept:The year 1914 marks the formal amalgamation of the Northern and Southern protectorates into one country called Nigeria.
Explanation:Before 1914, the area now called Nigeria was administered separately as the Northern and Southern protectorates.
British influence existed earlier through trading companies such as the Royal Niger Company, but there was no single unified administration.
In 1914, Lord Lugard officially merged the two protectorates to form one Nigerian entity.
This is why the event tied to 1914 is the amalgamation, not the beginning of British control or the start of the First World War.
Answer:C. year Lugard effected amalgamation of Nigeria.
