A quick update. I have completed a draft of a short history of the Faith for the period up to 1850, the dispensation of the Bab. It has grown bigger than expected - some 10,000 words. I made much use of Balyusi's great book on the Bab to guide me as to what to include - without quoting from it.
I include in this post a version of the map I include in the book. I tried to ensure the date of various events was clear so that the stories of those involved can be related to each other.
