TEHRAN -- For centuries, Persian served as the language of administration, scholarship and elite culture across the Indian subcontinent. 
Although its official status declined under British colonial rule, Persian remains deeply embedded in the literary, cultural and linguistic heritage of India and Pakistan.
The history of Persian in the subcontinent extends far beyond its role as a foreign or administrative language. For nearly a millennium, Persian became a central element of intellectual and cultural life, shaping courts, government institutions, religious schools, literary circles and historical writing. 
It was not merely the language of rulers but also a medium through which knowledge, poetry, philosophy and spiritual thought were transmitted.
The expansion of Persian began in the early centuries after Islam, gaining wider influence from the Ghaznavid period onward. With the rise of Muslim dynasties in parts of India, Persian gradually entered administrative and cultural institutions. 
Its spread was not solely the result of political power; Persian-speaking scholars, poets, administrators, mystics and intellectuals migrated to the region, while local elites also adopted the language as a means of participation in cultural and political life.
During the Delhi Sultanate, Persian became the language of official correspondence, royal decrees, historical chronicles and scholarly works. Knowledge of Persian was often essential for those seeking positions within government and intellectual circles. 
Over time, the language became a shared cultural medium connecting diverse communities across the subcontinent.
Persian reached its peak during the Mughal era, when it became the official and cultural language of one of the most powerful empires of the Islamic world. Mughal courts supported Persian literature, translation, historiography and scholarship, turning cities such as Delhi, Lahore, Agra and Hyderabad into major centers of Persian intellectual activity.
The subcontinent also became a major center for Persian literary production. Poets such as Amir Khusrau Dehlavi and Abdul Qadir Bidel demonstrated that India was not merely a recipient of Persian literature but one of its most important creative landscapes.
