How were the the messengers used in olden days?

In ancient times, messengers played a crucial role in communication, delivering important messages, news, and proclamations across distances. They traveled on foot, horseback, or by other means, often navigating challenging terrains to ensure timely delivery. Messengers were essential for military communications, diplomatic missions, and relaying information between rulers and their subjects. Their reliability and speed were vital for maintaining connections in a world that lacked modern communication technologies.
