The provincial style of Islamic architecture includes the introduction of the Islamic architectures and their gradual developments in the Indian subcontinent region in the medieval period. These Indo-Islamic architectures in India were introduced during the Islamic rules in different provinces which made tremendous growth especially in this field. These styles were neither Islamic nor Hindu but the fusion of both. The Muslim rulers tried to reshape the Hindu architecture by adding arch, dome and minar to their constructions as well as they also borrowed several Hindu styles and applied to decorate their buildings. Due to this many new features were introduced in their building art. The Muslims rulers during this period mostly created mausoleums, mosques, minarets, forts and palaces.

There were numerous reasons which conditioned the character of the provincial styles, one of which was the Muslim powers and their practice of arts at Delhi. When a province remained closely associated to the central power which was the Muslim dynasty, their effect on architecture grew strong, while this influence is less noticeable for the distant parts of the country. Another major factor in developing the provincial style was the nature of the indigenous arts which succeeded within the area of the province that flourished due to the association of local artisans. Another reason behind the development of provincial style in India was the migration of experienced foreign craftsmen to the court of different Muslim rulers. They were wonderful artisans and created amazing Islamic architectures and different principles of their native land mixing with Indian provincial culture. Sometimes climatic conditions also played a major role in developing a specific provincial style. In certain parts this climatic conditions imposed several technical differences, one kind of building material being common in some regions and rare in others, all of which naturally affected the character of the building art.

These provincial styles of Islamic architectures developed in Indian subcontinent from Punjab province and gradually expanded to the entire India. They constructed wonderful architectures with the fusion of typical Islamic style of Western Asia and the Hindu culture. The provincial developments of Islamic architecture .

Indian subcontinent were divided into following categories:

Indo- Islamic Architecture in Punjab: Punjab was the first province that experienced the Islamic architecture in Indian subcontinent. These architectures established in the city of Multan. Arab invaded the city from the Sindh region earlier in the eighth century. But the province received a permanent Islamic influence in the tenth century. The Indo-Islamic architecture of Punjab province was mainly of brickworks and produced highly decorated building arts. Their palaces were embedded with brickwork and other wooden elements, mainly their doorways, windows and other hanging balconies. These buildings were constructed in Islamic styles with the fusion of Hindu culture.

Indo- Islamic Architecture in Bengal: In the thirteenth century Arabs invaded the Bengal province and introduced their architecture for the first time in this region. These Muslim rulers constructed several new cities fortresses, palaces, free-standing victory-towers, citadels, immense land bridges and embankments, etc in this province that included present day Bangladesh and West Bengal in India. These architectures were maintained for a period of two hundred and fifty years. They created the buildings with the locally available building materials combining the regional styles with the typical Muslim features such as domes, arches, the minaret and the mihrab. This amalgamation resulted into a new and improved technique named as Indo-Islamic architecture, enriched with regional building tradition in Bengal.

Their skilled artisans constructed the buildings to its distinctive appearance and decorated wonderfully in which colour played an important role in their architectural scheme. They obtained this colour sequence partially by the use of various coloured stones and marble, and partially by means of encaustic tiles and used sand stone, marbles and semi precious stones for the construction of the buildings.
