Professor Bosworth's latest book continues the story he began in The Ghaznavids : their empire in Afghanistan and eastern Iran (Edinburgh, 1963) The first volume ended with the Ghaznavid defeat at the hands of the Saljuq invaders at Dandanqin in 431/1040. But the dynasty survived that disaster by nearly 150 years, and Bosworth's second volume concludes with its final extinction by the Ghürids in 582/1186. It is a much shorter book than The Ghaznavids since, as Bosworth says, ' the sources for the middle and later Ghaznavids are infinitely sparser than those for the earlier period '. Certainly it is useful to have available a concise, clear, and carefully researched account of the decline of this once-great dynasty.
Perhaps to characterize the period from 1040 to 1186 simply as one of decline ' is unjust : Bosworth stresses the cultural achievements attained under Ghaznavid patronage, and on the political side he suggests that it may well be that the reduction of the sprawling early Ghaznavid empire to a more manageable size was a source of strength rather than of weakness'—a view that the long survival of the empire might be held to confirm.

This work is clearly designed for the specialist as shown by the intense attention to detail. However, it's not like there are a whole lot of popular histories being written about medieval Afghanistan, so the book is definitely worth reading through if you have an interest in the topic.
