My topic is: To what extent did Belgian colonialism pave the way for the Rwandan Civil War?

I want to section my essay into Belgian colonization and then Rwandan Civil War. My teacher said I should focus more on Belgian colonization because I need to explain the extent part of the question. How belgian colonization in a way, caused the civil war in Rwanda. Any type of non-fictional sources would help me, as part of the IA, I need to mention my sources, but it will not be the entire component of the paper.

Sources need to be from books, 8 of them that I can use. They have to be contemporary sources, as I would like to eliminate any possibility of outdate or in other words, the possibility that my sources have been debunked or updated. And I am allowed 2 online resources. So you can see how, as a 17 year old who has never done this before nor has had something like this explained to or guided (and this is my entire IB graduating class we have not been helped..), could be stressing.

So far, I have: "Africa's World War" by Gerard Prunier "King Leopold's Ghost: A Story of Greed, Terror, and Heroism in Colonial Africa" by Adam Hochschild. (If you guys can tell me if these are professional and credentialed and I can count on these, that would be of great help.)

If any of you can help me, I would be most grateful.

P.S.: I, along with my entire class of 2016 IB students, have not been taught how to write something of such massive historiological proportion. We are are scrambling to find 8 qualified sources in a span of two days. She told us about the deadline last minute, and we know not a knick of contemporary history, I mean, none whatsoever. I'm scared and I want to do a good job, and I can't turn to anyone else because I don't know any historians. My teacher does not offer help, I have asked and received none, she just threw this on us.

Sorry if this is a bother, I just really need some help.

Thank you to all.

With much regards, TheAndromedaGalaxy
