The dynasty was established by Sayyid Khizr Khan, deputised by Timur to be the governor of Multan (Punjab). Khizr Khan took Delhi from Daulat Khan Lodi on May 28, 1414 and founded the Sayyid dynasty. But he did not take up the title of sultan and nominally, continued 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 was succeeded by his son Sayyid Mubarak Shah after his death on May 20, 1421, who styled 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 Shah ascended the throne and styled himself as Sultan Muhammad Shah. Just before his death, he called his son Sayyid Ala-ud-Din Shah from Badaun and nominated him as his successor.

Ala ud-Din Khilji (r. 1296-1316) was the second and the most powerful ruler of the Khilji dynasty of Delhi Sultanate in South Asia.

Alauddin was a nephew and a son-in-law of his predecessor Jalaluddin. When Jalaluddin became the Sultan of Delhi after deposing the Mamluks, Alauddin was given the position of Amir-i-Tuzuk (equivalent to Master of ceremonies). Alauddin obtained the governorship of Kara in 1291 after suppressing a revolt against Jalaluddin, and the governorship of Awadh in 1296 after a profitable raid on Bhilsa. In 1296, Alauddin raided Devagiri, and used the loot to stage a successful revolt against Jalaluddin. After killing Jalaluddin, he consolidated his power in Delhi, and subjugated Jalalaudidn's sons in Multan.
