Timur appointed Khizr Khan as his deputy to oversee Timurid interests in the Punjab marches. Khizr Khan (1414-21) went on to seize Delhi and establish the Sayyid dynasty (1414–51). 

• The Sayyid dynasty established by Khizr Khan had four sultans ruling up to 1451. The early Sayyid Sultans ruled paying tribute to Timur’s son.  
• Their rule is marked for the composing of Tarikh-i- Mubarak Shahi by Yahiya bin Ahmad Sirhindi. By the end of their rule the empire was largely confined to the city of Delhi. 
• In the entire history of the Delhi Sultanate there was only one Sultan who voluntarily abdicated his throne and moved to a small town away from Delhi, where he lived for three full decades in contentment and peace. He was Alam Shah of the Sayyid dynasty.
