Genghis Khan would be more accurately described as a destroyer of cities than a slayer of people, because he often razed entire cities for strategic reasons in addition to revenge or to provoke fear. In a massive and highly successful effort to reshape the flow of trade across Eurasia, he destroyed cities on the less-important or more inaccessible routes to funnel commerce into more routes that his army could more easily supervise and control. To stop trade through an area, he demolished the cities down to their very foundations.
