On the one hand, the British introduced a number of administrative and legal reforms that helped to modernize Nigeria and improve the lives of its citizens. They also established a system of education that produced a new generation of leaders who were committed to national unity and development.
On the other hand, the British also implemented policies that caused resentment among Nigerians, such as the imposition of colonial rule, the exploitation of resources, and the unequal distribution of power and wealth. These policies contributed to the eventual independence of Nigeria and the rise of ethnic nationalism.
It is important to note that the Igbo, Yoruba, and Hausa-Fulani are not monoliths. There were significant differences in opinion within each group about the role of the British and the direction of Nigerian society. Some individuals welcomed British rule as a positive force, while others saw it as a threat to their culture and way of life.
In conclusion, it is inaccurate to claim that the British style of government worked better with one ethnic group than others. Each group experienced a complex mix of advantages and disadvantages during the colonial period.
