How to Plan a Crusade: Religious War in the High Middle Ages

The story of the wars and conquests initiated by the First Crusade and its successors is itself so compelling that most accounts move quickly from describing the Pope's calls to arms to the battlefield. In this highly original and enjoyable new book, Christopher Tyerman focuses on something obvious but overlooked: the massive, all-encompassing and hugely costly business of actually preparing a crusade. The efforts of many thousands of men and women, who left their lands and families in Western Europe, and marched off to a highly uncertain future in the Holy Land and elsewhere have never been sufficiently understood. Their actions raise a host of compelling questions about the nature of medieval society. How to Plan a Crusade is remarkably illuminating on the diplomacy, communications, propaganda, use of mass media, medical care, equipment, voyages, money, weapons, wills, ransoms, animals, and the power of prayer during this dynamic era. It brings to life an extraordinary period of history in a new and surprising way.

Review :
"An impressive synthesis of a complicated subject, presented in elegant, readable prose. Not many historians could have done it." -- The Spectator "His deeply researched study is dedicated to exploring the relationship between human reason and religious war in all its aspects-justification, propaganda, recruitment, finance, logistics-to show us how 'reason made religious war possible.'" -- The London Review of Books "Mining details on logistics 800 years ago is Tyerman's forte, and he throws them on to the page like chaff from a trebuchet. It is comprehensive, laying down a great skein of fact where there was only supposition (much of it false). And, as the West gears up for the crusade against Islamic State, it is horribly timely." -- The Times (London) "Fascinating not just for what it has to tell us about the Crusades, but for the mirror it holds up to today's religious extremism." -- Tom Holland - The Mail on Sunday "Serious and scholarly, the synthesis of decades of work on difficult, fragmented sources. An impressive and lively book, laced with wry asides and enough surprising details to pique the general reader." -- Jessie Childs - The Guardian
