The Malabar coast in the southwestern region of the Indian subcontinent has had a maritime trade relationship with the Arab world since ancient times. In the wake of Islam in the Arab world, a ubiquitous need for a mosque was necessitated to perform the prayer wherever Muslims stayed. Hence, the oldest mosque in the Indian subcontinent is said to have been built in the Malabar region. In the early eighth century (91 Hijri), an Umayyad army Commander, Mohammad bin Qasim al Thaqafi, invaded the subcontinent and built the mosques at Banbhore, Mansura, and Udigram in Sindh (now in Pakistan). The remains of the grand mosque at Bhanbhore did not have the mihrab that attributed it to the very early mosque of Islam. Later, by the end of the twelfth century, Islamic Sultanate was established in the North. Delhi, Agra, Lahore, and Fatehpur Sikri were the four capitals of Muslim rule in the North of the subcontinent. Being the first confronter and the epicenter of Muslim rule, North India observed the most prolific development of mosque architecture in the subcontinent. However, with a regional and provincial architectural accent, several typologies of mosque morphology were developed in medieval India, such as Gujarat, Jaunpur, Bengali, Deccani, Malwa style, etc. Every dynasty of the Sultanate and Mughal period in medieval India contributed to the development of mosque architecture with distinguished features. However, the morphological changes and the continuity of mosque architecture were influenced by regional and foriegn architecture and several sociopolitical conditions of the region. Through the spatial, decorative, and structural elements and finishing materials, this research studies the morphological development of mosque architecture in North India in medieval times. With the help of literature, observations, analysis, and comparison of case studies, the research explores the influences on Indian medieval mosque architecture. The study is limited to medieval India’s three capitals of Islamic rule: Delhi, Agra, and Fatehpur Sikri.
