On 26th August 1303, Alauddin Khilji of the Khilji Dynasty attacked and captured Chittorgarh by defeating Ratan Singh in a historic battle. This was an unequal battle since Khilji's army was much bigger than Ratan Singh's army. After winning Khilji handed over the Chittorgarh to his son Khizr Khan. Khilji gave the responsibility of the fort to his minor son, Khizr Khan, renamed Chittor as Khizrabad, and returned to Delhi. Meanwhile, from Khiljis, the power in Delhi shifted to the Tughlaq Dynasty. Rana Amar Singh (First), the eldest son and successor of Maharana Pratap, got back the Chittaurgarh Fort after a treaty with Mughal King Shah Jahan in 1615.
