I think this book does an excellent job of breaking down the history of the multiple conflicts that have happened in Sudan post-independence and puts them into easy to understand contexts.
It starts with British colonization and the missteps that have hindered many African nations post-scramble for Africa. Uniting a colony that has political borders that indiscriminately place people of different ethnicities into a new country is a difficult task. Much like modern Sudan, colonial Sudan had also had a majority of its resource allocation center on the Arab, Muslim, and Northern half of the country. The non-Arab, Christian, and Southern half was an afterthought in colonial and post-colonial development. Because the center of power was in the North, as Sudan was just about to gain independence, the Arab, Muslim families in Khartoum were closer to the centers of power and were able to adopt stewardship of the newfound country in independence.
The author writes about the history of the identity politics that drive these conflicts and why Sudan is a "dissolving" state. The North/South conflict is separate from the Darfur genocide. The author writes about the modern shift of mindsets of the conflicts. Originally, pre-Darfur conflict, Sudanese wars could be thought of simply as wars between the North and the South. Darfur shifts that mindset to Khartoum vs. periphery. The book also has chapters about how oil exploration exasperates these conflicts and leads western democracies to turn a blind eye to genocide to protect private/corporate profits. The government in Khartoum also recruited and harbored Islamic extremist groups to wage warfare against citizens, the Janjaweed being a prime example.
While the book was written pre-2010, and the conflicts that ravage Sudan have probably changed a ton since (South Sudan is its own country now) this was a really informative book that gave me a lot of context to the genocides the Sudanese government has exacted on its citizens.
