Need help with my World History Writing Homework about Ghana’s transition

As nations in Africa gained independence from colonial powers, some made relatively smooth transitions to self-rule while others experienced violence and upheaval. In some nations, the violence continues even today. What might have been done to help those nations transition to self-rule peacefully? Write a short essay that sets forth ideas on ways that violence and civil war might have been prevented.

You might consider:

Why Ghana’s transition to independence was peaceful

Why French colonies tended to have more peaceful transitions than the colonies of other European powers

Who lived in the colony at the time of independence; for example, ethnic groups, religious groups, European elites, and so forth.
