Historians note Ala ud-Din Khalji as being a tyrant. Anyone Ala ud-Din suspected of being a threat to this power was killed along with the women and children of that family. He grew to eventually distrust the majority of his nobles and favored only a handful of his own slaves and family. In 1298, between 15,000 and 30,000 people near Delhi, who had recently converted to Islam, were slaughtered in a single day, due to fears of an uprising. He is also known for his cruelty against kingdoms he defeated in battle.
