A good and interesting wide lens survey of the Crusades. It is helpful that he includes the larger view of crusades outside of the middle east. It does not deliver any new insights or perspectives. If you want to have a deeper insight I recommend; Holy War: The Crusades and Their Impact on Today's World
by Karen Armstrong.

“Crusaders” is definitely an ambitious take on a subject that has already had so much written about it. Dan Jones goes well beyond the Levant and Egypt to also include the Reconquista in the Iberian Peninsula, the oft-forgotten Baltic Crusades, Sicily, and elsewhere throughout three different continents. Despite the hefty reach over both its geographic and chronological range, it successfully avoids turning into a bog of place names, names of rulers, and dates. The finely crafted historical narrative keeps its path intact all the way from start to finish.

The only mild complaint is that there definitely were points where I felt the coverage of certain items felt a bit thin. But then again, trade offs will be inevitable in the construction of a history that will be both accessible and expansive. And considering all that it needs to encompass, “Crusaders” does the best job that it can possibly do striking that balance between accessibility and and detailed depth. Overall, Dan Jones has pulled together a history that is quite impressive in its simultaneously intimate yet sweeping review of the religious wars whose influence continues to reach out to the present day.
