The Sayyid dynasty ruled the Delhi Sultanate from 1415 to 1451. The Timurid invasion and plunder had left the Delhi Sultanate in shambles, and little is known about the rule by the Sayyid dynasty. Annemarie Schimmel notes the first ruler of the dynasty as Khizr Khan, who assumed power by claiming to represent Timur. His authority was questioned even by those near Delhi. His successor was Mubarak Khan, who renamed himself Mubarak Shah and unsuccessfully tried to regain lost territories in Punjab from Khokhar warlords.
