Mehmed bin Süleyman Fuzuli, Fuzuli also spelled Fuḍūlī (born c. 1495, Karbalāʾ, Iraq—died 1556, Karbalāʾ), Turkish poet and the most outstanding figure in the classical school of Turkish literature.

A resident of Baghdad, Fuzuli apparently came from a family of religious officials and was well versed in the thought of his day, but very little is known about his life. Among his early patrons was Shāh Esmāʿīl I, founder of the Ṣafavid dynasty of Iran and conqueror of Baghdad in 1508. Twenty-six years later, when the Ottoman sultan Süleyman I took Baghdad, Fuzuli attempted to curry favour with his new masters and henceforth wrote in the name of the Ottoman sovereign. It seems that he was never able to move to the Ottoman capital Constantinople (Istanbul), however, but remained in Iraq throughout most of his life.

He composed his famous Şikâyetname (“Complaint”), in which he caustically commented on not being given the status of court poet in Constantinople. Fuzuli composed poetry with equal facility and elegance in Turkish, Persian, and Arabic. Although his Turkish works are written in the Azerbaijani Azeri dialect, he had a thorough knowledge of both Ottoman and Chagatai Turkish literary traditions.
The works for which he is famous include his melodic and sensitive rendition of the great Muslim classic Leylâ ve Mecnun. This celebrated allegorical romance depicts the attraction of the Majnūn (the human spirit) for Laylā (divine beauty). Fuzuli is the author of two divans (collections of poems), one in Azerbaijani Turkish and one in Persian. These anthologies contain examples of his most lyrical poetry, many concerned with mystical love and others lamenting the ephemeral nature of this world. His poetic expression, characterized by sincerity, passion, and a pervasive strain of melancholy, transcended the highly formalized classical Islāmic literary aesthetic. Fuzuli’s works influenced many poets up to the 19th century.
