"Over 9 million refugees and internally displaced people from conflicts in Africa. Hundreds and thousands of people have been slaughtered from a number of conflicts and civil wars." The source is here.
Wikipedia lists over 50 African countries that have been involved in war. The list is here.
I followed civil war in Rwanda. I have just read the book, "a long way gone". I have heard atrocities of war in the Congo. I have Liberian refugees in my class. Why is Africa at war?
If you would like a learned paper, please read, "Why are there so many civil wars in Africa."
One of the reasons cited in the paper is poverty. A brilliant depiction of the Tragedy of the Commons is on Marginal Revolution. Private property instills the incentive to produce. Of course, those rights have to be enforced. This brings me to the question, can there be private property without government?
