“Genghis” wasn’t his real name.
The man who would become the “Great Khan” of the Mongols was born along the banks of the Onon River sometime around 1162 and originally named Temujin, which means “of iron” or “blacksmith.” He didn’t get the honorific name “Genghis Kahn” until 1206, when he was proclaimed leader of the Mongols at a tribal meeting known as a “kurultai.” While “Khan” is a traditional title meaning “leader” or “ruler,” historians are still unsure of the origins of “Genghis.” It may have may have meant “ocean” or “just,” but in context it is usually translated as “supreme ruler” or “universal ruler.”
He was tolerant of different religions.
Unlike many empire builders, Genghis Khan embraced the diversity of his newly conquered territories. He passed laws declaring religious freedom for all and even granted tax exemptions to places of worship. This tolerance had a political side—the Khan knew that happy subjects were less likely to rebel—but the Mongols also had an exceptionally liberal attitude towards religion. While Genghis and many others subscribed to a shamanistic belief system that revered the spirits of the sky, winds and mountains, the Steppe peoples were a diverse bunch that included Nestorian Christians, Buddhists, Muslims and other animistic traditions. The Great Khan also had a personal interest in spirituality. He was known to pray in his tent for multiple days before important campaigns, and he often met with different religious leaders to discuss the details of their faiths. In his old age, he even summoned the Taoist leader Qiu Chuji to his camp, and the pair supposedly had long conversations on immortality and philosophy.
He created one of the first international postal systems.
Along with the bow and the horse, the Mongols most potent weapon may have been their vast communication network. One of his earliest decrees as Khan involved the formation of a mounted courier service known as the “Yam.” This medieval express consisted of a well-organized series of post houses and way stations strung out across the whole of the Empire. By stopping to rest or take on a fresh mount every few miles, official riders could often travel as far as 200 miles a day. The system allowed goods and information to travel with unprecedented speed, but it also acted as the eyes and ears of the Khan. Thanks to the Yam, he could easily keep abreast of military and political developments and maintain contact with his extensive network of spies and scouts. The Yam also helped protect foreign dignitaries and merchants during their travels. In later years, the service was famously used by the likes of Marco Polo and John of Plano Carpini.
