Tughlaq in the context of "Khizr Khan"

Khizr Khan (1361 – 20 May 1421) was the Sultan of Delhi from 1414 to 1421. He was the founder of the Sayyid dynasty, the fourth ruling dynasty of the Delhi sultanate, in northern India soon after the invasion of Timur and the fall of the Tughlaq dynasty.Khizr Khan was Governor of Multan under the Tughlaq ruler, Firuz Shah Tughlaq, and was known to be an able administrator. He did not take up any royal title due to fear of invasion by Amir Timur (better known historically as Tamerlane) 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 continued to be struck in the name of previous Tughlaq rulers. 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.
