The method that was used by the Europeans to control the administration of Southern Nigeria was "Divide and Rule". This approach involved dividing the people of Southern Nigeria along ethnic and regional lines in order to weaken their unity and make it easier to control them. By exploiting existing rivalries and tensions among different groups, the Europeans were able to maintain their dominance and prevent the emergence of a united front against their colonial rule. This approach was particularly effective in Southern Nigeria, which was home to a large number of diverse ethnic groups with their own distinct cultures and traditions. By playing one group against the other, the Europeans were able to maintain control over the entire region without facing significant resistance. Overall, the "Divide and Rule" method was a key strategy used by European powers during the colonial era to maintain their control over the regions they had conquered. While it was effective in achieving their goals of dominance, it often had long-lasting negative effects on the societies and cultures of the regions affected by this approach.
