yep, it was called the "dark ages" 10,000 year rule of a mighty black empire that conquered most of modern day europe and parts of asia

china has a history of a ruthless "black empress" during the shang dynasty who killed her own servants and was into human ritual sacrifice, of course when she died she made all her servants commit suicide by drinking a poison and were all buried with her in a PYRAMID

this is a closely guarded secret

many of the black shang dynasty people later escaped the dynasty wars that came afterwards or were killed during civil war in china's ancient history
