I thought this was excellent.
There is relatively little 'Qatari history' which makes this book an excellent, and detailed coverage of much previous work and current scholarship. Morton covers the formation of the state extremely well and manages, through a clear and concise narrative, the weave complex tribal and clan-based affiliations and geographies into a coherent and readable historical narrative and analysis. Relations with Saudi and the Emirates and with Bahrain and particularly well done here to allow the casual reader an opportunity to untangle the complexities of some of the relationships.
My only criticism was that, even with the dirth of historical evidence, I would have liked a 'chunkier' coverage of the Qatari peninsula from prehistory through the Islamic Empires to the modern formation. Archaeological details, though scarse, could have allowed for a little more detail.
