The Persian Empire was known for its efficient administration and the use of a courier system called the Angarium. This system facilitated rapid communication across the vast empire through a network of couriers and relay stations, allowing for the swift transmission of messages and official decrees. The Persian Empire, particularly under leaders like Cyrus the Great and Darius I, created a highly organized governance structure that managed diverse cultures and regions. The Angarium was an essential tool for maintaining control and coherence across this expansive territory, contributing to the empire's longevity and effectiveness.
