In the past, Qutb Shahi rulers and Nizams attracted artists, architects and men of letters from different parts of the world through patronage. The resulting ethnic mix popularised cultural events such as mushairas (poetic symposia). The Qutb Shahi dynasty particularly encouraged the growth of Deccani Urdu literature leading to works such as the Deccani Masnavi and Diwan poetry, which are among the earliest available manuscripts in Urdu. Lazzat Un Nisa, a book compiled in the 15th century at Qutb Shahi courts, contains erotic paintings with diagrams for secret medicines and stimulants in the eastern form of ancient sexual arts. The reign of the Nizams saw many literary reforms and the introduction of Urdu as a language of court, administration and education. In 1824, a collection of Urdu Ghazal poetry, named Gulzar-e-Mahlaqa, authored by Mah Laqa Bai—the first female Urdu poet to produce a Diwan—was published in Hyderabad.
