Alauddin Khilji his parents when he was young and was raised by his uncle
Alauddin Khilji lost both of his parents when he was very young. He was born in West Bengal's Birbhum area. When his parents passed away, he became the son-in-law/nephew of Jalaluddin, the First Sultan of the Khilji dynasty, who was responsible for raising Alauddin and his three brothers.
Jalal-ud-din, who was originally known as Firuz, began his career as a Mamluk dynasty official and later attained prominence under Sultan Muizzuddin Qaiqabad. A gang of nobles attempted to assassinate Jalal-ud-din when Qaiqabad became crippled and named his young son Shamsuddin Kayumars as the new Sultan. As a substitute, Jalal-ud-din had them killed and took over as regent. He overthrew Kayumars a few months later, becoming the new Sultan.
When Jalaluddin became the Sultan of Delhi, he nominated Alauddin as Amir-i-Tuzuk (Master of ceremonies) and his younger brother Almas Beg as Akhur-beg (Master of the Horse). His uncle gave him important positions in his government, but in return, he paid with his life and the loss of his kingdom because Alauddin Khilji treacherously murdered him and ascend the throne in 1296 CE.
