Making Sense of the Central African Republic is a collection, edited by Tatiana Carayannis and Louisa Lombard, of shorlarly articles on CAR. It’s probably the most comprehensive book you’ll get on the country, though it was published in 2015 and so misses out more recent developments. There’s articles from a mix of experts, including Central African academics.
It captures both the macro an micro, with articles looking at the broad sweep of CAR’s history and it’s identity – how it is caught between the politics and identities of Sahel countries like Chad and Sudan in the north and the Congo Basin in the south. It also gets into the micro, examining the Pk5 neighbourhood, which has both flourished as a trade hub and been fought over.
The works also build up a larger picture of how a state like CAR ends up so fragile or even failed – the ineffectiveness of peacekeepers, rent-seeking from elites and outsiders, and how natural resources underpin most of the chaos.
