Hyderabad was named by a prince Muhammad Quli Qutb Shah, who then became the Sultan of the Qutb Shahi dynasty. He named it after a Hindu village lass named Bhagamathi, who he fell in love with and married. When Muhammad Quli founded the city, he named it Bhagyanagar in her honour. When she embraced Islam and changed her name to "Hyder Mahal," the city's name was changed to match it and has since been called Hyderabad, literally, "the city of Hyder."
It is also suggested that the city got its name from the honorary title of the fourth Caliph of Islam, Ali ibn Abi Talib who is referred to in the Islamic literature as Haydar-i Karrar (The swift moving Lion ), particularly due to the alleged Shi'ah leanings of the Qutb Shahi rulers.
