The subsequent Slave dynasty of Delhi managed to conquer large areas of northern India, while the Khilji dynasty conquered most of central India but were ultimately unsuccessful in conquering and uniting the subcontinent. The Sultanate ushered in a period of Indian cultural renaissance. The resulting "Indo-Muslim" fusion of cultures left lasting syncretic monuments in architecture, music, literature, religion, and clothing. It is surmised that the language of Urdu (literally meaning "horde" or "camp" in various Turkic dialects) was born during the Delhi Sultanate period as a result of the intermingling of the local speakers of Sanskritic Prakrits with immigrants speaking Persian, Turkic, and Arabic under the Muslim rulers. The Delhi Sultanate is the only Indo-Islamic empire to enthrone one of the few female rulers in India, Razia Sultana (1236–1240).
Is there an answer to this question (If it cannot be answered, say "unanswerable"): By what is the fusion of Islamic and Indian cultures called?
Indo-Muslim
