The Golden Horde of Mongols, led by Genghis Khan, ravaged most of the known world in the 13th century, from China to Rome. Everything in between was left in carnage or total surrender and they amassed the greatest treasure ever imagined. Legend has it that the treasure was buried with their Khan but there were no witnesses, because the burial party was killed to keep it a secret. The archaeological world may have found a sacred royal burial site, the Asian equivalent of the Valley of the Kings in Egypt. But is this the tomb of Genghis Khan himself?
