Chapar Khaneh
"Chapar Khaneh" is a Persian term for the postal service used during the Achaemenid era. The system was created by Cyrus the Great, the founder of the Persian Empire, and later developed by Darius the Great, as the royal method of communication throughout the empire. Each "Chapar Khaneh" was a station mainly located along the Royal Road, a 2500 km ancient highway, which stretched from Sardis to Susa, connecting most of the major cities of the empire.
Herodotus' description of the "Royal Road" and the various "Chapar Khanehs" along it is as follows:
The "Chapars" were express couriers who were provided with fresh supplies and horses at each station along the way, allowing them to quickly complete their way without having to procure supplies on their own or wait for their horse to rest.
