Good morning, everyone. Today we're going to discuss the history of the postal service. Many people assume that postal systems were invented in Europe, but in fact, the earliest known postal system dates back to ancient China around 2000 BCE. It was primarily used by the emperor to send military orders across the vast empire. Later, the Persian Empire developed a more organized relay system using horses and messengers. However, it was the Romans who introduced a public postal service for civilians, though it was initially reserved for government officials. By the 19th century, the introduction of the postage stamp revolutionized mail delivery, making it affordable for ordinary people. So, the key point is that the concept evolved gradually over centuries.
