Persian emerged as a dominant language in Bengal beginning in the early 13th century, particularly after the establishment of independent Muslim dynasties. By the mid-14th century, Persian was not only the language of administration but also a key cultural medium. Historian Richard Eaton highlights that Bengal serves as a linguistic archive, preserving Persian vocabulary that has since disappeared in Iran. The Mughal Empire, especially under Emperor Akbar, further solidified Persian's status as the official language of governance, which enabled it to flourish in literature and administration. The Nawabs of Murshidabad, who gained autonomy from the Mughals, continued to promote a Persianized culture, fostering an environment rich in Persian literature and arts. However, the British colonial period marked a significant decline in the status of Persian, particularly after the 1837 legislation that replaced it with local vernaculars and English in administrative functions. Despite this decline, Persian's influence persists in Bengali language and culture, reflecting a complex historical relationship that has shaped modern Bengali identity.
