Explanation:

 In 1301 Alauddin Khalji, the ruler of the Delhi Sultanate in India, conquered the neighbouring kingdom of Ranastambhapura (modern Ranthambore).

Hammira, the Chahamana (Chauhan) king of Ranthambore, had granted asylum to some Mongol rebels from Delhi in 1299. He refused requests to either kill these rebels or hand them over to Alauddin, resulting in an invasion from Delhi. Hammira lost his general Bhimasimha to an army led by Alauddin's general Ulugh Khan, and his brother Bhoja defected to Alauddin some days later.
