Good morning, everyone. Today we're going to discuss the history of the postal service. As you know, modern postal systems rely heavily on technology, but the origins go back much further. For instance, the ancient Persians developed a relay system using horses and messengers, which could cover about 200 miles in a single day. However, it was the Romans who established the first official postal network, known as the 'cursus publicus', primarily for military and governmental communication. Interestingly, ordinary citizens were not allowed to use it until much later. This system was quite efficient, with stations placed every few miles to change horses. So, while the Persians had speed, the Romans had organization and scale.
