The term “barbarian,” we know, was originally applied by the Greeks to all non–Greek speakers—captured slaves as well as quite “civilized” neighbors such as the Egyptians, the Persians, and the Phoenicians. “Ba-ba” was meant to be a parody of the sound of non-Greek speech. In one form or another the term was reinvented by all early states to distinguish themselves from those outside the state. It is fitting, therefore, that my seventh and last chapter is devoted to the “barbarians” who were simply the vast population not subject to state control.
