To best understand Christopher Tyerman's impressive God's War: A New History of the Crusades (Belknap/Harvard), you must go back more than a half century, to when Sir Steven Runciman produced his three-volume History of the Crusades.

For all of its eccentricities, including such heavy-handed moralizing, Runciman's work is a beautifully written classic that has inspired several generations of historians to engage in Crusade studies.
