This family claimed to be Sayyids, or descendants of Prophet Muhammad. The central authority of the Delhi Sultanate had been fatally weakened by the invasion of Timur (Tamerlane) and his sack of Delhi in 1398. After a period of chaos, when no central authority prevailed, the Sayyids gained power at Delhi. Their 37-year period of dominance witnessed the rule of four different members of the dynasty.
The dynasty was established by Khizr Khan, deputised by Timur to be the governor of Multan (Punjab). Khizr Khan took Delhi from Daulat Khan Lodhi on May 28, 1414 and founded the Sayyid dynasty. But he did not take up the title of king 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[1]. Khizr Khan was succeeded by his son Mubarak Khan 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 Khan ascended the throne and styled himself as Sultan Muhammad Shah. Just before his death, he called his son Ala-ud-Din from Badaun and nominated him as his successor.
The last ruler of this dynasty, Ala-ud-Din Alam Shah voluntarily abdicated the throne of the Delhi sulatanate in favour of Bahlul Khan Lodhi on April 19, 1451 and left for Badaun. He continued to live there till his death in 1478[2].
