Qutb-ud-din Mubarak Shah was the third and the last ruler of khilji dynasty in India. He was the son and successor of Alauddin Khilji, who belonged to Pashtun of the Ghilzai tribe.

Qutb-ud-din Mubarak Shah`s younger brother, who was only six years old became the king and Qutb-ud-din was his regent at the age of eighteen. However, Qutb-ud-din blinded his brother within two months and became the king. He started his reign by releasing thousands of prisoners and forgiving all taxes and penalties imposed by his father Alauddin Khilji.

In the year 1320, his malefavorite Khusru Khan assasinated him and announced himself as the king. This ended the Khilji dynasty.
