Question

How was slave dynasty overthrown by khilji dynasty?

Answer 1

Qutb ud-Din Aibak became the sultan of Delhi, and that was the beginning of the Slave dynasty. ... The Khalji dynasty came into being when Jalal ud din Firuz Khalji overthrew the last of the Slave dynasty rulers, Muiz ud din Qaiqabad, the grandson of Balban, and assumed the throne at Delhi.

Answer 2

The nobles control the Delhi sultanate after Balban's death. Balban had nominated Kai Khusrau, his eldest son, as the ruler. However,the noble supported Qaiqabad, the son of Bughra Khan (an independent ruler of Bengal). He ascended the throne with the help of the nobles. This power tussle went on for a very long time. It was after a period of 2 years that Jalaluddin Khilji, another prominent noble, ascended the throne. Thus, began the reign of the Khalji dynasty.
