The worst impact of European colonization was that a culture of violence was created.  The Europeans solved their problems in Africa through violence.  When the Europeans left Africa, the only way that the Africans knew how to solve problems was by violence.  That led to many problems for them later on.
   In African countries, there was only one way they knew how to remove their leader from power. That would be to force him or her out of power.  Most of the first leaders were forced out of power.  Some of them were killed in the process, but nobody knew any other way.  There really wasn't any other way because there wasn't any voting.  If there was conflict between countries, they wouldn't just talk it out.  It would not end well at all.
