Kublai Khan established the first Pony Express

Kublai Khan established the first Pony Express-style postal services in Mongolia about 1,000 years ago when correspondence was carried by a horse, and urgent messages—to which a feather was attached—were carried hundreds of miles a day on horseback nonstop. The Mongolian horse post became a special state service named örtöö (“checkpoint”), which remained in operation until 1949. The route had fixed relay stations, situated some 18–25 miles (30–40) km apart. One of the many duties of the Mongolian mail courier was to carry out tours of duty with carts and animals at the örtöö, or supply a substitute, and carry mail or travelers to the next station.
