This book has a concise history also.

In brief, one of our brothers who is living in an English speaking countryused to suffer from the isolation of his fellow Shi’ites and their poor knowledge of their history, their Imams, their school of thought and other related religious matters. This is due to the lack of information available in the English language and their own deficiencies in Arabic or other islamic languages that could provide them with the neccessary background and references.

This dear brother of ours was so dedicated to Islam and keen on finding a solution to help his Muslim brothers that he thought of compiling a concise book about the history of the Fourteen Infallibles i.e. The Holy Prophet, his daughter fatima Az-Zahra and the Twelve Imams, peace be upon them all.
