The first regular postal service in the world was established in ancient Persia in 6th century BC during the reign of the first king of the Achaemenids, Cyrus the Great (550 BC-529 BC). The riders would stop at regularly placed “post houses” to get a fresh horse and to pass on their packages, mails of dispatches to another messenger for the remainder of the distance.
“Neither snow nor rain nor heat nor gloom of night stays these couriers from the swift
completion of their appointed rounds”, said the Greek historian Herodotus.
The Persians made use of a highly efficient relay-style delivery
system more than two millennia ago.
The Achaemenid Persian Empire (550-330 B.C.) which ultimately ruled over 23 nations spread across approximately 3,000,000 square miles stretching from North Africa to Indus Valley was based on law and order. According to Herodotus, even the kings were not allowed to put a man to death for an offense. An ideal Persian leader had to be intelligent, decisive, just, and guarantor of civil order.
