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 those nations transition to self-rule peacefully?

When nations gained independence from colonial powers, the reason why some were able to transition quite peacefully while others were experiencing violence and upheaval was that there were different interest groups in terms of what they wanted from a specific country.

In essence, where nations didn't transit to self-rule peacefully, other nations could have made sure that they would be able to transition peacefully through different ways of helping their fellow neighbouring nations. 

Thats not a question. what do you want me to do?
