In 1311 Delhi Sultanate ruler Alauddin Khalji dispatched an army to capture the Jalore Fort in present-day Rajasthan, India. Jalore was ruled by the Chahamana ruler Kanhadadeva, whose armies had earlier fought several skirmishes with the Delhi forces, especially since Alauddin's conquest of the neighboring Siwana fort. Kanhadadeva's army achieved some initial successes against the invaders, but the Jalore fort ultimately fell to an army led by Alauddin's general Malik Kamal al-Din. Kanhadadeva and his son Viramadeva were killed, thus ending the Chahamana dynasty of Jalore.
