Yup.
What I find weirdest are those people who seem to think the Nazis set some sort of record for people-killing efficiency, when they were actually pretty pathetic in that category.
Multiple times the Mongols captured a city with a surviving population of perhaps 500,000. The people would be captured, bound and marched out. Perhaps a half dozen would be distributed to each soldier in the 100,000 Mongol army, and on a signal everybody would chop heads. Then build a pyramid with them.
They’d ride away, leaving the bodies lie, and send a group back in a couple of weeks to slaughter any who had managed to hide in the ruins.
IOW, they’d routinely kill perhaps 500,000 people in just a few minutes. With the only added expense the labor of resharpening their swords and axes.
Compare that to the Nazis, who hauled victims all over Europe wasting desperately needed transport resources, and then at Auschwitz managed to hit a peak “production” of only around 20,000 per 24 hours, if I remember the numbers right.
People today seem to think really mass killing requires technology and industrial methods. In actual fact all you need is a whole bunch of enthusiastic killers.
The "enthusiastic killers" thought they were doing RIGHT.
After Genghis, his GRANDSON took over the killing. It took Asia a L-O-N-G time to recover from the invasions of the Khans.
