How did Kublai Khan’s road system assist travelers and messengers?

Under the reign of Kublai Khan, the Mongol Empire utilized an extensive network of postal relay stations known as the yam to facilitate communication, administration, and long-distance travel.1

This system functioned as a series of strategically placed relay stations that allowed messengers and travelers to move efficiently across the vast empire. By providing a structured network of stops, the yam ensured that official communications could be transmitted rapidly and that travelers had access to necessary support, which significantly improved the connectivity and governance of the Mongol Empire. This infrastructure was a key component of the Pax Mongolica, a period that also saw the revitalization of the Silk Road through the protection of merchant caravans and the issuance of official passports called paiza.1
