The struggle to usurp the reign over nations amongst local africans in the post-colonial era was affecting countries all over the continent. Some times the transfer of power were conducted in the absence of war. In some countries the end of colonialism brought with it bloody conflicts that would battere the stability for a nation in years to come. Some countries fought the colonial empire for independence and other was granted the freedom. Some european settlers hade made their colony their home and a source of income, and though the empire that onces conquer the land no longer had means to rule it, some of its settlers did. Whilst in other cases, tribes native to the once colonized land created unrest due to their lack of believe in the new regim and had a wish for governance over their own lands. Noriyuki Katagiri’s theory on how insurgents win wars against a state is based mainly on studies conducted on conflicts between colonial empires and insurgents. This study aims to examine wether Katagiris theory is applicable in conflicts between previous colonies which gained independence but still is ruled by an unpopular government rather than the local natives. The results of this study will perhaps bring new understandings of the outcome of conflicts by examining the rebellion in the region Katanga in Congo in the early 1960s aswell as the conflict in Rhodesia between 1965 and 1979.
