Shah Rukh. After the accession of Khizr Khan, the Punjab, Uttar Pradesh and Sindh were reunited under the Delhi Sultanate, where he spent his time subduing rebellions. Khizr Khan was succeeded by his son Sayyid Mubarak Shah after his death on 20 May 1421. Mubarak Shah referred to himself as Muizz-ud-Din Mubarak Shah on his coins, removing the Timurid name with the name of the Caliph, and declared himself a Shah. A detailed account of his reign is available in the Tarikh-i-Mubarak Shahi written by Yahya-bin-Ahmad Sirhindi.
