Answer:
There are many reasons why African nations were unprepared to take over their leadership of their countries. One of the most pressing challenges African states faced at Independence was their lack of infrastructure. European imperialists prided themselves on bringing civilization and developing Africa but they left their former colonies with little in the way of infrastructure.
Another reason is that African nations did not undergo industrial revolutions. This meant that they were still rural and backward nations with a system of education ranging from ineffective to nonexistent. The power unit at the bottom of the administrative structure is still the village with local chiefs in charge of local affairs. The power structure is essentially feudal.
African leaders consistently have failed to be on the lookout against pitfalls which have sabotaged their work and plunged their countries into economic and governance failures, or downright chaos.
