Genghis Khan established an incredibly efficient postal system across the Mongol Empire in the 13th century, utilizing a massive network of relay stations that allowed riders to cover up to 200 miles in a single day. Known as the Yam, this communication network was so fast and reliable that it essentially functioned as the medieval equivalent of broadband internet, keeping the vast empire connected through sheer horse power and the looming threat of brutal executions for anyone who slowed down the mail. Messengers wore special bells so station masters knew to have a fresh horse ready, allowing them to ride continuously without stopping for trivial things like sleep or maintaining a reasonable heart rate. It is incredibly ironic that a warlord most famous for burning entire civilizations to the ground somehow managed to build a courier service that was arguably more reliable and punctual than modern postal delivery systems
