The Mongols Created the First International Postal System Called the Yam

One of the most impressive achievements of the Mongol Empire was the creation of the Yam, a sophisticated postal relay system that connected the vast empire. This network of stations allowed messengers to travel extraordinary distances at high speed by changing horses at regular intervals. A message could travel from the Mongol capital to the edges of the empire in just a few days, a journey that previously took months. The system was so efficient that riders could cover up to 200 miles per day. The Yam stations provided fresh horses, food, and lodging for official messengers and travelers. This communication network was crucial for administering the massive empire and maintaining control over distant territories. The system was later admired and emulated by other civilizations, including Marco Polo who described it in detail.
