State communications in the Neo-Assyrian Empire
The state communications in the Neo-Assyrian Empire allowed the Assyrian king and his officials to send and receive messages across the empire quickly and reliably. Messages were sent using a relay system (Assyrian: kalliu) which was revolutionary for the early first millennium BCE. Messages were carried by military riders who travelled on mules. At intervals the riders stopped at purpose-built stations, and the messages were passed to other riders with fresh mounts. The stations were positioned at regular intervals along the imperial highway system. Because messages could be transmitted without delay and without waiting for riders to rest, the system provided unprecedented communication speed, which was not surpassed in the Middle East until the introduction of the telegraph. The efficiency of the system contributed to the Neo-Assyrian Empire's dominance in the Middle East and to maintaining cohesion throughout the empire. These Assyrian innovations were adopted by later empires, including the Achaemenid Empire which inherited and expanded the Assyrian communication network. History The Neo-Assyrian Empire was an Iron Age empire centered in Mesopotamia. The reign of Adad-nirari II () was considered the start of the empire.
