Today we're going to discuss the history of the postal service. Many people assume that the postal system began in the 19th century with the introduction of stamps, but in fact, organized mail delivery dates back much further. For example, in ancient Persia, around 550 BC, a system of mounted couriers was established to carry messages across the empire. These couriers could travel about 200 kilometers in a day, which was remarkable for that time. However, the service was limited to royal use. It wasn't until the 16th century that postal routes were opened to the public in Europe, and even then, only for letters, not parcels.
