Yams of the Great Khān
In order to ensure that messengers could travel fast enough to keep up with Mongol armies, Genghis Khān instituted a system of relay stations or yams, which were set up every 30-60 km to provide food, shelter and spare horses for Mongol army messengers. This allowed messages to travel as fast as a horse can gallop, with fatigue no longer slowing the speed a messenger could travel. By these means, our empire was able to overcome the logistical problems caused by the vast scale of the Pax Mongolica - at least temporarily.
