Bloody wars engulfed the entire planet long before Columbus, and they were bloodiest in India and China - parts of the world you evidently know nothing about.

China's thousands of internal wars by hundreds of warlords killed untold tens of millions over the centuries. And of course, the Mongols were famous for depopulating cities of up to a million people, and stacking mountains of heads outside their burned remains.
