The Khilji Dynasty was founded in Delhi on 13 June 1290 with the ascension of Jalal-ud – din Khilji as the Delhi Sultan.
The Mamluk dynasty ruled Delhi in the starting of the year 1290 A.D. The tenth and last line ruler was Muiz ud din Qaiqabad, it has been said Jalal-ud – din Khilji murdered him. When a community of Qaiqabad nobles put his infant son, Kayumars at the throne, they were killed by Jalal-ud-din and the infant was deposed.
Then Jalal-ud-din overtook the crown, and on 13 June 1290 declared Sultan of Delhi, that marked the beginning of Delhi’s Khilji dynasty.
Jalal-ud-din, born Firoz, was a member of the originally Turkish Khilji tribe. Since the tribe had been living in Afghanistan for some time but at Delhi court, they were considered to be Afghans.
Malik Firoz, as Jalal-ud-din had been known before he became the Sultan, was originally a military officer in the army of the Mamluk dynasty.
Qaiqabad had appointed him to an influential military role because he had succeeded in repelling Mongolian invasions.
In 1296, his nephew and son-in-law Alauddin Khilji murdered Jalal-ud-din, who then took the title, Sultan of Delhi.
In the southern part of the world, Alauddin annexed further territory and expanded the sultanate. His generals gained huge spoils of war from the Southern Kingdoms that helped to reinforce the Khilji rule. The famous Koh-i-Noor diamond was stolen by Alauddin’s army in 1310 from the Kakatiya dynasty at Warangal.
20 Years ruled by Alauddin and his General Malik Kafur became the king after his death in 1315 but was murdered in a few months.
The next three years saw three sultans take power in different coups only to be murdered. Shihab-ud-din Omar was positioned on the throne with his brother Qutab ud din Mubarak Shah as the regent, after Malik Kafur, a 6-year-old son of Alauddin.
One of his generals Khusraw Khan, in turn, murdered Mubarak Shah. An Army commander Ghazi Malik killed Khusraw Khan, who had become the Sultan. Ghazi Malik then ascended to the Delhi throne and adopted the name of Ghiyasuddin Tughlaq, that marked the start of the Tughlaq dynasty.
