Genghis Khan Nearly Erased A Kingdom From History For Not Sending Troops
When Genghis Khan attacked Khwarezmia, he asked the conquered kingdom of Xi Xia to send him troops. They refused. Xi Xia tried to take a bold stand against their oppressor, and they quickly regretted it. The Mongolian army swarmed through Xi Xia, destroying everything that they found. They systematically exterminated every member of the population.
By the end, Xi Xia was erased from history. They hadn’t written down their own stories, so the only records of their existence came from neighboring countries. Their language wasn’t recovered for more than 700 years. It took until the mid-20th century for archaeologists to unearth stones that had their writing on them. In the meantime, every word they had spoken was forgotten.
Genghis Khan died during the battle, most likely from being thrown from his horse. Still, the Mongolian army carried out his work. They slaughtered every person they found, even after their leader was dead and their enemy had surrendered.
