This book relates the story of the involvement of a French priest, known as Peter the Hermit, in the Frank – Byzantine – Sunni Seljuk Turk – Shia Fatimid Egyptian religious and territorial war at the end of the eleventh century. He was a very talented speaker able to inspire those around him with great confidence to face the difficult task of marching from Cologne in Germany to Jerusalem on the East coast of the Mediterranean Sea, facing many hardships on the way. This account is very personalised as the author uses historical records of various communications to establish the characters of some of the participants in this crusade and thus to suggest the reasons for their actions.
