The Bengali language is not an original regional language evolved through the intermingling of tribal and Sanskrit languages. It was accepted as a major regional language under the Mughal rule. The rich Bengali literature can be divided into two categories i.e. I. Derived from Sanskrit books like the Mangalakavyas and Bhakti literature like the autobiographies of Chaitanyadeva, and II. Original literature like Maynamati, Gopichandra, Dharma Thakur stories, folktales and fairy tales.
Alongside Mughals started building mosques and the leaders of which were called Pirs. The term Pir was used to address saints or Sufis and other religious personalities, daring colonisers and deified soldiers, various Hindu and Buddhist deities, and even animistic spirits.
Powerful individuals and groups started building temples to display their goodness and the Bengali style of temple architecture went through an evolution like the double roof (dochala) and four-roofed (chauchala) on thatched huts.
The temples were built on square platforms and the builders focused on creating exquisite exteriors decorated with paintings, ornamental tiles or terracotta tablets while the interiors were kept plain. Rice and fishing make the staple food of the Bengalis. Fish was so popular a chief diet that even the Brahmins consumed it as per the Sanskrit text Brihaddharma Purana.
