Yam (Mongolian: Өртөө, Örtöö, checkpoint) was a postal system or supply point route messenger system extensively used and expanded by Ögedei Khan and also used by subsequent great khans and khans.[2]
Relay stations provided food, shelter and spare horses for Mongol army messengers. Ögedei Khan gave special attention to Yam because Mongol armies travelled quickly; their messengers had to be even faster, and they covered 200–300 kilometres (120–190 mi) per day.[2] The system was used to speed up the process of information and intelligence.
The system was preserved in the Tsardom of Russia after the disintegration of the Golden Horde.
