We tend to be a quiet lot (except during the annual bacchanalia we call the International Congress on Medieval Studies in Kalamazoo, Michigan, of all places), poring over musty chronicles and writing dull yet meticulous studies that few will read. With the possible exception of Umberto Eco, medieval scholars are not used to getting much media attention. This piece, from 2002, after 9/11, notes Bill Clinton seemingly trying to justify Islamic terrorist behavior by reaching back to the Crusades, just as President Obama seemed to do yesterday at the National Prayer Breakfast.
By the time of the Crusades, Muslims had already captured 2/3 of the Christian world.
