Medieval Persian refers to the Persian language as it was used from the 9th to the 15th centuries, particularly during the Islamic Golden Age. This period saw the development of a rich literary tradition, with notable works in poetry, philosophy, and science. The language evolved from Old Persian and was influenced by Arabic due to the Islamic conquests. During this time, Persian became the cultural and administrative language of various empires, including the Samanid and Safavid dynasties. It played a crucial role in the exchange of ideas across Central Asia and the Middle East, fostering a vibrant intellectual environment.
