Postal Service Technology Timeline

 The evolution of the postal service throughout history shows one overarching theme: humanity's desire for connection and need to communicate across extensive distances. Through my research, there were different examples of empires or regions that claimed to develop the first postal service. 

For example, some of the earliest documented postal systems dates back to ancient Egypt around 2400 BCE. During this time, pharaohs used couriers (a person employed to deliver messages, documents, or packages quickly) to deliver decrees across their territories. At this time--and until the Middle Ages--the main purpose of the postal service was for government communication across their empire or territory.

Furthermore, there also were similar systems developed in other civilizations around this time period: the Han Dynasty, Islamic Empire, and the Mughal Empire are all key examples of the early forms of the postal service that developed a foundation for the system we know today. 

Another example of an ancient form of the postal service was the Zhou Dynasty in China. Developed nearly 3,000 years ago, it reflected similar goals as other early regions like Egypt: to facilitate communication between the central government and and regional authorities, specifically for military and administrative purposes. 

This was important because it allowed these empires to formulate plans for strategic defense and transit official commands. Something I found interesting is how drastically the purpose of the postal service has changed over time; now, we use the postal service to support our individual consumerism and personal communications.

Looking closer at ancient China--specifically the Zhou Dynasty--they had a very intricate system for developing a postal service in their empire. The system worked as follows: the Chan system delivered messages by vehicle; the You system relied on foot couriers; and the Yi system, which used horse couriers to maximize speed. 

Additionally, relay stations were known as Zhi, which served as resting points where couriers could exchange horses, rest, and prepare for the rest of their journey. 

The shift from government communication to personal communication started slowly in the Middle Ages. According to Britannica, Paris was one of the first cities where they "started to maintain corps of messengers to serve their particular needs." The main reason for the lack of personal communication was due to the lack of literacy. Only a small portion of civilians knew how to read and write, making it unnecessary for personal communication.

The catalyst for the change in literacy rates and personal communication can be credited to Johannes Gutenberg and his development of the printing press. Invented in 1450, this machine helped change the narrative regarding literacy. 

Now, because of the long-standing postal service traditions across various nations, our society is able to be more connected than ever. If we order something, chances are we see it on our doorstep the next day. Globalization created the need for universal access of information, allowing messages to travel quicker than ever.
