The Sayyid dynasty is the fourth dynasty of the Delhi Sultanate from 1414 to 1451.

They succeed the Tughlaq dynasty and rule the sultanate until they are displaced by the Lodi dynasty.This family claims to be Sayyids, descendants of Muhammad.

After Timur sacks Delhi and ends the Delhi Sultanate in 1398, he appoints Sayyids as the governor of Delhi.

Their thirty-seven-year period of dominance witnesses the rule of four different members of the dynasty.The dynasty is established by Khizr Khan, deputized by Timur to be the governor of Multan (Punjab).

Khizr Khan takes Delhi from Daulat Khan Lodi on May 28, 1414 and founds the Sayyid dynasty, but he does not take up the title of sultan and nominally, continues to be a Rayat-i-Ala (vassal) of the Timurids, initially of Timur and after his death, his successor Shah Rukh, grandson of Timur.

Khizer Khan is succeeded by his son Mubarrak Khan after his death on May 20, 1421, who styles himself as Muizz-ud-Din Mubarak Shah in his coins.

A detailed account of his reign is available in the Tarikh-i-Mubarak Shahi written by Yahya-bin-Ahmad Sirhindi.

After the death of Mubarak Shah, his nephew Muhammad Khan ascends the throne and styles himself as Sultan Muhammad Shah.

Just before his death, he callshis son Ala-ud-Din from Badaun and nominatsd him as his successor.The last ruler of this dynasty, Ala-ud-Din Alam Shah voluntarily abdicates the throne of the Delhi sultanate in favour of Bahlul Khan Lodi on April 19, 1451, and leaves for Badaun, where he will remain until his death in 1478.
