Conflict in africa was largely the result of a system under which an outside government take control of an area for its own benefit. balkanization, urbanization, colonization, ethnic cleansing

The answer is colonization.  Many European countries took control of the African continent and used its manpower and resources for their own benefit.  What is worse is the way they treated the people who lived there by making them servants in their own homes.  Some European countries still exert influence in the region even though many African countries gained their independence.

the ss was the main organization responsible for the genocidal murder of around six million people of european ethnic minorities, essentially jews, in the holocaust. the members of all its branches committed war crimes and crimes against humanity during the second world war (1939-1945). likewise, the ss were involved in commercial enterprises and exploited the inmates of the concentration camps as slave laborers.

the tortures and assassinations committed by the ss were the result of an ideology developed long before the armed conflict, this ideology was based on the racial supremacy of the germans over the rest.
