Ameer Muawiyah (R.A) was the founder and first caliph of the Umayyad Caliphate, serving from 661 until his death. 

He is credited with establishing government departments responsible for the postal route (Barid), correspondences, and chancellery. 

The postal service was the state-run courier service of the Umayyad and later Abbasid Caliphates. Mu’awiyah’s successor Abd al-Malik ibn Marwan strengthened the organization, making additional improvements to it after the end of the Second Fitna.
