Khizr Khan
Khizr Khan ibn Malik Sulaiman (reigned 1414-21) was the founder of the Sayyid dynasty, the ruling dynasty of the Delhi sultanate, in northern India soon after the invasion of Timur and the fall of the Tughlaq dynasty. He was known to be an able administrator. He did not take up any royal title from fear of Amir Timur and contended himself with the titles of Rayat-i-Ala (Sublime Banners) and Masnad-i-Aali or (Most High Post). During his reign, coins were struck in the name of Amir Timur and after his death in the name of his successor Shah Rukh. After his death on 20 May 1421, he was succeeded by his son Mubarak Khan, who took the title of Muizz-ud-Din Mubarak Shah.
