I read Half of a Yellow Sun thinking I would find out what really caused the war. I hear phrases like the factors that led to war are still with us today. But the book did not do a good enough job at all of addressing the real reason war broke out. It skirted around the issue really. It was a rather disappointing read. It only sprinkled references to the notion that people thought the Igbos wanted to control everything. Or at least that is what I thought Chimamanda made reference to at one point.The Rwandan genocide was heard the world over. Then again, that was in the 1990's. Most Africans are lost to the fact that a civil war ever broke out in Nigeria. I don't think 8 out of 10 West Africans even know about it. Not my generation.
What's more, Ojukwu used propaganda as a key weapon in the war, so a lot of work was done to "advertise" the war, with the images of starving children broadcast across the world. Many Western celebrities (most notable being John Lennon and Yoko Ono) staged very public protests against the war. It was on the covers of all the magazines and newspapers throughout Europe and the USA and it was on TV every single night.
If you or others of your generation don't know that there was a civil war in Nigeria it's certainly not because it was never given any coverage.
