Answer:
Mongol Empire
One significant innovation of the Mongol Empire was their use of a sophisticated communication system known as the Yam. The Yam was a vast network of postal stations and messengers that allowed the Mongols to quickly and efficiently transmit messages across their vast empire. This was a remarkable achievement considering the sheer size of the Mongol Empire, which spanned over 17 percent of the world's landmass and encompassed a quarter of the global population.
The Yam system consisted of a series of relay stations that were spaced out at regular intervals along major trade routes and strategic locations. Each station was staffed with fresh horses and messengers, who could quickly carry letters, documents, and other messages to the next station. The system was highly efficient and reliable, allowing messages to travel thousands of miles in just a matter of days.
This innovation was significant because it allowed the Mongols to maintain control over their vast and diverse empire. By facilitating rapid communication, the Yam helped the Mongols to coordinate their military campaigns, enforce their laws and policies, and administer their territories. Additionally, the Yam system facilitated cultural and economic exchange between different parts of the empire, promoting the spread of new ideas, technologies, and goods.
Today, the legacy of the Yam system can still be seen in the many historical sites and artifacts that have been discovered along the old trade routes of the Mongol Empire. For example, the ruins of relay stations and postal inns have been found throughout Central Asia, China, and Iran. This serves as a testament to the innovative spirit of the Mongol Empire and their remarkable achievements in the fields of communication and transportation.
