Which traveller described the postal system prevalent in India in the medieval period in detail ?

Ibn Battuta, the Moroccan traveller who visited India during the reign of Muhammad bin Tughlaq (14^th century), provided a vivid and detailed account of the Indian postal system in his travelogue, Rihla.

He described two distinct types of postal services:

• Uluq: The horse post, which used royal horses stationed at intervals of every four miles.
• Dawa: The foot post, which had three stations per mile. At each station, runners stood ready to carry messages to the next point.

Battuta was particularly impressed by the efficiency of the foot post, noting it was often faster than the horse post and was used to transport essential items and news across the empire rapidly. While other travellers like Bernier and Pelsaert wrote about Mughal India, Battuta's specific and detailed classification of the Tughlaq-era postal system is a hallmark of his writings.
