Chapar means “the house of courier” or the “messenger (JSK)” which was the first generation of the postal service created by Cyrus the Great, the founder of the Persian Empire.
This communication service covered the Persian Empire from Europe, Asia Minor, Egypt, Babylon, Aden, and Arabia to the Indian Ocean. The messengers were carrying mail by day and night. The relay stations, “chapar-khaneh”, were built only so far apart from each other so that a horse could run without resting or feeding. Thousands of kilometers of roads were built to facilitate the delivery of mail throughout the Persian Empire.
Chapari was later adopted as the method of communication throughout the empire.
