Cyrus Established The World's First Postal

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. The Persians made use of a highly efficient relay-style delivery system more than Two Millennia Ago.
