Ibn Battuta, who visited India during the rule of Muhammad bin Tughlaq, recorded one of the most detailed accounts of the postal system in the Delhi Sultanate. According to his writings, there were two main network systems: one operated using mounted horse messengers and the other using trained runners. These relay stations were placed at short intervals, allowing rapid communication across the empire. His description highlights the administrative efficiency and communication network that helped maintain political control over distant territories. His writings serve as a valuable historical source for understanding governance during the Sultanate era.
