After the ravages of Amir Timor at Delhi and the end of Tughlaq Dynasty, Khizar Khan founded the Sayyed Dynasty in the north of India of the medieval ages. His claim to the throne was recognized by Sayyed Jalal-ud-Din, the religious chief of Bukhara. Though the historians have quoted him as the descendent of the
Prophet of Islam (Peace be upon Him) but his father (Malik Suleman) had been adopted as his son by Malik Mardan Daulta, the governor of Multan and not Sayyed Jalal-ud-Din with whom he had a devotion. The son of Malik Mardan Daulat died and was succeeded by Malik Suleman who took over as the new governor of Multan and after the death of Malik Suleman, the governorship of Multan came to Khizar Khan, his son. He was expelled by Sarang Khan in 1395 AD and was forced to flee to Mewat where he joined Timor. Reportedly, Amir Timor left him as his Nybe of the Sultanate but he contended only to Multan, Depalpur and a few parts of Sindh. After coming into power, he came across Malu Iqbal Khan and then Daulat Khan Lodhi whose defeat brought him to the avenues of power and became the first ruler of Sayyed Dynasty.
Khizar Khan, unlike the other kings before him, did not title him with heavy names and sat on the throne as Rayat –e Ala (the exalted banner) all his life submitting to Shah Rukh, the son of Timor. He did not issue the coins in his name and contended the name of Timor and his son Shah Rukh on the coins even in his age. He appointed Malik-ul-Sharq Malik Tohfa as his minister with the title of Taj-ul-Mulk who accompanied him till his death in 1421 AD. Khizar sent Taj-ul-Mulk to curb Har Singh, the Raja of Katehar in 1414 AD. Another expedition was sent to Gwalior, Patali and Bayana under the trusted minister Taj-ul-Mulk in July 1416 AD to receive homage from these areas. He received the money by looting the farmers and local people to fill the treasure.
In 1417 AD Khizar Khan sought permission of Shah Rukh to include his name on the coins after the name of Shah Rukh. Khizar invaded Gujrat and he plundered Jhain, Bayana, and Gwalior on his return to Delhi. In 1418 AD Khizar Khan sent Taj-ul-Mulk to curb the rebellion of Doab and Katehar. Har Singh, the Raja of Katehar (who had revolted again) fled to the forest but was arrested by Taj-ul-Mulk and was released after his pledge of paying tribute to the Sultan. Koel and Sambhal near Delhi were raising opponent voices which were noticed and answered by him. He sent Islam Khan, the governor of Sirhind to compress the rebels of Bijwara in the east Punjab whereas Taj-ul-Mulk set off to appease the rebels of Koel and Itawa and looted Chandwar and Katehar retuning to Delhi. In 1421 AD Khizar Khan invaded Gwalior and Mewat but he had to come back to Delhi due to his illness of which he died on May 2, 1421 AD.
Khizar Khan was succeeded by his son Mubarak Khan who took over as Moiz-ud-Din Mubarak Shah who was surrounded by the revolts all around him. His rule lasted for thirteen years though could not appease the rebellions in the empire and finally fell a prey to the enemies in 1334 AD.
