The Mongol Yam: How Riders Swapped Horses at 40 MPH

In this episode, Lucas and Luna dig deeper into the Mongol Yam relay system — but this time, they zoom in on the nuts and bolts: the physical infrastructure, the staggering speed of communication, and the human cost behind the empire's information superhighway. Drawing on accounts from Marco Polo, William of Rubruck, and the Persian historian Juvayni, they explore how Yam stations were spaced exactly one day's ride apart, how riders could cover 200-300 miles in a single day by swapping horses at every post, and how the system was funded by a tax on every household in the empire. Lucas explains the harsh penalties for failing to maintain a station — including death — and reveals that the Yam was so efficient that news could travel from Beijing to the Volga in under two weeks. They also touch on how Kublai Khan expanded the system to include foot runners and boat routes, and how the Yam indirectly enabled the Black Death's spread along the Silk Road. A focused, concrete look at one of history's most remarkable communication networks. #MongolEmpire #Yam #GenghisKhan #KublaiKhan #MarcoPolo #WilliamOfRubruck #Juvayni #SilkRoad #BlackDeath #RelayRiders #CommunicationHistory #CentralAsia #13thCentury #Karakorum #Khanbalik #PostalSystem #History #FexingoHistory #YamSystem #MongolPostalSystem Keep every episode free: buymeacoffee.com/fexingo
