The Yam's Cipher Breakers: Mongol Postal Codebreaking

In the 13th century, the Mongol Empire's Yam postal system was the most advanced communication network in the world. But what happened when messages were intercepted? In this episode, Lucas and Luna explore the forgotten art of Mongol codebreaking. They delve into the secret ciphers used by Mongol couriers, the tamgha seals that authenticated messages, and the bitikchi scribes who devised increasingly complex encryption methods. Discover how the Mongols countered espionage by enemy states like the Mamluks and Song Dynasty, and how they used captured codebreakers to crack enemy communications. Learn about the role of the Yassa legal code in protecting postal secrets, and the fate of one Persian vizier who tried to read the Khan's private mail. This episode reveals a hidden layer of the Yam's history — not just as a relay system, but as a battlefield of wits.
