He installed one of the first international postal systems
One of the earliest worldwide postal systems in the world is credited to Genghis Khan, according to historians. Ortoo was the name given to this system in the Mongol Empire. Communication stations were utilized in this system for the delivery of official mail. Additionally, the stations were utilized by military personnel, foreign dignitaries, and traveling officers. Additionally, these stations assisted in the transportation of both domestic and foreign commodities.
The Mongols' extensive communication network may have been their most effective weapon, along with the bow and the horse. One of his first orders as Khan was to establish the "Yam," a mounted courier service. This medieval express was made up of an efficient network of post houses and way stations dispersed throughout the entire Empire. Official riders may frequently cover up to 200 miles per day by resting or switching mounts every few miles. The system served as the Khan's eyes and ears while also enabling the movement of products and information at an unheard-of rate.
He could easily stay up to date on military and political developments and stay in touch with his vast network of spies and scouts because of the Yam. Additionally, the Yam provided protection for traveling merchants and dignitaries from other countries. Later on, notable people like Marco Polo and John of Plano Carpini used the service.
