This is a general review of the history of the First Crusade, which was the expedition sent from Western Europe under the auspices of the Church of Rome, to capture and reclaim Jerusalem from her Muslim rulers. The flow of the narrative works rather well. Not too much time is spent on particularities of battles, but rather a broad picture is given so that the reader experiences the major points of contention in each skirmish, and the effects and aftereffects on the Crusading armies.
Likewise, with an obviously huge cast, the author focuses in on a handful of Crusader princes, the Byzantine Emperor, and the Pope. We learn a bit about each man, but are not drowned in historical minutiae. The author makes great pains to stress that the original intent of the Crusades was indeed a holy one, but through hardship and exposure to new lands and the enticement of power, many of the Crusaders subjugated their religious fervor into the expropriation of power.
Primarily, this books is about the Westerners, with some digression to the Byzantine Emperor and his court. The opposing Muslims war lords, however, are not fully explored. I think this does a great disservice to the book, and although the Muslims are not caricatures, they are not fully human, either. Their frame of mind is not explored, nor much of the history of how Islam became the dominant religious force in the area, nor much about how the various Islamic states, and their shifting alliances, came to be
Additionally, the author grazes over the differences between Latin and Greek Christians. At the time of the First Crusade, in 1098, the Great Schism was less than fifty years in the past. Instead of pointing merely to the increase in papal authority and ambition, and the rather minute differences in liturgical and spiritual life, a more thorough discussion about the Schism and political, as well as the theological, ramifications of it would have been helpful, particularly as the Crusaders left behind a few Latin bishops and patriarchs in place of the indigenous Greek/Byzantine ones. The concluding chapter rightly notes that the Crusade became a benchmark in later Christian/Islamic relations, but it was for Latin and Greek Christians, as well.
Thankfully, this is not a hagiography of the Crusaders, and we are not spared the atrocities committed by the Crusaders in the name of their God. They were definitely a bloody bunch, with no problems massacring the elderly, women, children, and infants in the cities they overran. The bloodbath committed in Jerusalem is particularly revolting. Although the Muslim treatment of people they conquered is not mentioned, in warfare, both sides were brutal and savage, as it seems to be the way war was waged in those times.
Worth checking into if you'd like a brief history of the First Crusade. The book is actually just 339 pages, the rest being a glossary, footnotes, and selected bibliography.
