Adoni has undergone a number of substantial changes over the past few centuries. Emerging as a military base for the Vijayanagara Empire in the 15th century, the city has evolved to become a modern, manufacturing hub. Under the Vijayanagara, the city stood at the center of the consolidation of a shifting, fragmented countryside into a more structured empire. Even after the Empire fell in the 16th century, as a product of military conflicts, the city remained a core part of Southern Indian history.

In that year, he surrendered to the Mughal general Anup Singh, maharaja of Bikaner.

Art historian Mark Zebrowski notes in his book Deccani Painting that the capture of Adoni revealed that Siddi Masud had been an avid collector of painting, and a patron of the Kurnool school of painting.
After the decline of the Mughal Empire, Adoni remained under governors appointed by the Nizams of Hyderabad. In 1760, it was held by Basalut Jung, who made it his capital.
