how did genghis khan's die

Genghis Khan died in August 1227 while on a military campaign against the Western Xia empire. The exact cause of his death remains uncertain and has been the subject of much speculation and legend. According to historical sources, he fell ill during the campaign and died after about eight days of sickness. Modern research suggests the illness might have been bubonic plague, typhus, or another infectious disease. Other theories include death from injuries sustained in a fall from his horse, being wounded by an arrow, or an assassination story involving a princess. However, these latter stories are generally regarded as myths or exaggerated legends. His death was kept secret at the time to maintain the morale of his troops during the ongoing campaign. After his death, his body was returned and buried in a secret location in Mongolia, near the sacred Burkhan Khaldun mountain, according to his wishes.
