The sultanate is noted for its integration of the Indian subcontinent into a global cosmopolitan culture (as seen concretely in the development of the Hindustani language and Indo-Islamic architecture), being one of the few powers to repel attacks by the Mongols (from the Chagatai Khanate) and for enthroning one of the few female rulers in Islamic history, Razia Sultana, who reigned from 1236 to 1240.
