Romance of Dewal Devi with Khizr Khan: Khizr Khan was the eldest son of Ala-ud-din Khilji. We first hear of him on the occasion of Ala-ud-din Khilji’s conquest of Chittorgarh in 1303. We are told that when Chittor was reduced, Ala-ud-din conferred the government of it on Prince Khizr Khan, and the place was renamed as Khizrabad. A few days after the arrival of Dewal Devi at Delhi, the prince became enamored of her beauty and they fell in love with each other. The Sultan wished to betroth her to Khizr Khan. But Mallika Jahan, mother of the prince, objected this since she wished to betroth him to the daughter of her brother Alp Khan. When she came to know about the prince’s affair with Dewal Devi, she thought means to separate them. Afterwards they were placed in different apartments, but still they met occasionally. The queen mother was anxious of these meetings and decided to sent Dewal Devi to the Red Palace of Siri fort. On that occasion, Khizr Khan in distress, “tore off his clothes and exhibited other signs of frantic grief”. But when he became normal, the queen mother again determined to sent Dewal Devi to the Red Palace. On her way she met Khizr Khan; he presented her with a lock of his hair to preserve as a memento, and she gave him a ring.
Marriage of Dewal Devi with Khizr Khan (1312): The queen mother arranged the marriage of Khizr Khan with the daughter of Alp Khan. But, seeing her son in deep distress, she finally gave her consent to his marriage with Dewal Devi.
