Europe has always been a rather tenuous concept. A rump continent, Europe represented the barbarous hinterlands for the Greeks and Romans. The first use of the term “European” occurred in a chronicle describing the forces of Charles the Hammer that turned back the northward advance of Islam at the battle of Tours in 732. Long celebrated in Europe as a victory of civilization over barbarism, the Battle of Tours was, as historian David Levering Lewis reminds us in God’s Crucible actually the opposite: “the victory of Charles the Hammer must be seen as greatly contributing to the creation of an economically retarded, balkanized, fratricidal Europe that, in defining itself in opposition to Islam made virtues out of religious persecution, cultural particularism, and hereditary aristocracy.”
