A young son of the Sultan was placed on the throne and Malik Kafur acted as the regent. Malik Kafur killed other members of the Allauddin's family but he was murdered and Mubarak Khan the third son became the regent. He imprisoned Sahibuddin and ascended the throne as Qutub uddin Mubarak in the year 1316. He tried to win the good will of the people.
He liberalized Alauddin's rigorous administrative policies and repealed economic regulations. All prisoners were released and harsh regulations were cancelled. The lands which were confiscated were given back to their legitimate owners. Taxes were lowered. He was under the influence of youth called Hassan who later was called Khusru Khan who conspired to kill him. Thus Khalji dynasty came to an end. Khusro tried to strike a reign of terror to control the nobles. This was resented by the nobles particularly Ghazi Malik who captured and beheaded the sultan. He ascended the throne under the title of Ghiyasuddin Tughlaq Shah.
