Theories explaining the origins and etymology behind Hyderabad's name differ. A popular theory suggests that after founding the city, Muhammad Quli fell in love with and married a local Banjara girl known as Bhagamathi. He named this city after her as Bhagyanagaram. Upon her conversion to Islam, Bhagamathi changed her name to Hyder Mahal and the new city's name was correspondingly changed to match it, resulting in the eponymous name Hyderabad (literally, "the city of Hyder").

Hyderabadi Biryani is the city's famous meat-and-rice dish.

It is a traditional celebration meal made using goat meat and rice and is the staple of a die-hard Hyderabadi. The Hyderabadi Biryani is so named as it is created in the city of Hyderabad, India. The blending of mughlai and Telangana cuisines in the kitchens of the Nizam (ruler of the historic Hyderabad State), resulted in the creation of Hyderabad Biryani.
