The Pashtun emperor Sher Shah Suri, who founded the Sur Empire centered at Delhi, turned Peshawar's renaissance into a boom when he ran his Delhi-to-Kabul Shahi Road as a northwestern extension of the Grand Trunk Road through the Khyber Pass and Peshawar in the 16th century. Later Babur's grandson, Akbar the Great, recorded the name of the city as Peshawa, meaning The Place at the Frontier or Near Water and expanded the bazaars and fortifications. The Muslim technocrats, bureaucrats, soldiers, traders, scientists, architects, teachers, theologians and Sufis flocked from the rest of the Muslim world to the Islamic Sultanate in South Asia, with many settling in the Peshawar region.
