Adoni is located in the Kurnool district of Andhra Pradesh. The municipality of Adoni also functions as the headquarter of the Adoni Mandal and the Adoni Revenue Division. Adoni has a population of more than 1.5 lakh residents, who speak in Telugu. Adoni was a fort town of the famous Vijayanagara Empire during the 15th to 16th centuries. After the decline of this glorious empire, Adoni went into the hands of Ali Adil Shah I of the Bijapur Sultanate. The Mohammedan rulers soon captured the area within a few years. The area was tossed to the hands of the Nizams and the Marathas and finally went to the British. In the late 19th century, Adoni faced a severe El Nino famine which claimed nearly one-third of its population. Adoni became a part of Andhra Pradesh in 1953. Adoni is a huge producer of cotton.
