Genghis Khan (1162-1227), the founder and great khan (emperor) of the Mongol empire, defeated Song emperors and established the Yuan dynasty.
As head of the ruling clan, he united the nomadic tribes of the Mongolian plateau and established the largest land empire in history, conquering huge swaths of central Asia and China.
His descendants expanded the empire even further, advancing to such far-off places as Poland, Vietnam, Syria and Korea. At its peak, the empire covered between 28.5 million and 32 million contiguous square kilometers, an area equivalent to the size of Africa.
Many people were slaughtered in the course of his invasions, and Genghis Khan was known for the brutality of his campaigns.
He acquired land through slaughter and war, but eventually realized enough was enough and that a certain restraint was required.
This restraint was heavily influenced by Taoist master Qiu Chuji, founder of the Dragon Gate sect. Qiu, the most famous of the Seven True Taoists of the North, was also an expert in feng shui and astrology.
In a May 1219 letter, Genghis Khan asked Qiu to pay him a visit. The sage left Shandong in February 1220 and only caught up with Genghis Khan near the northern Indian border in 1222.
Genghis Khan honored Qiu as a great sage, giving him the title of Spirit Immortal.
Qiu advised Genghis not to hunt as that would mean more killing. On Qiu's advice, Genghis Khan granted religious freedom throughout his empire, abolished torture, encouraged trade and created the first international postal system. He also called for restraint against further unnecessary slaughter.
Genghis Khan died in 1227 during a military campaign against the Chinese kingdom of Xi Xia. His final resting place remains unknown.
To this day, many Japanese and other foreigners have been looking for his tomb to no avail.
Some feng shui masters believe that his tomb will show a feng shui setting and orientation that befits the most powerful leader of the era.
