According to an account of the visiting Persian chronicler Abdur Razzak, Deva Raya II's empire extended from Ceylon to Gulbarga, and Orissa to the Malabar.
From the account of the contemporary European explorer Nicolo Conti, the king levied tribute on Ceylon, Quilon, Pegu, Pulicat and Tenasserim.
During an uncertain period that followed in c. 1443, when the king appears to have been a victim of an attempted assassination, some regions in the Tungabhadra River-Krishna River doab were lost to the Bahamani Sultanate.
According to this account, with an intent of strengthening his army, Deva Raya II employed many expert Muslim archers and cavalry and this incited the war.
According to Razzak who was eye witness to the episode, a brother of Deva Raya II invited the king and many important nobility to a feast and had most of the invitees beheaded.

Razzaq who was also an ambassador at the court of Deva Raya II wrote:"This prince has in his dominions three hundred ports, each of which is equal to Calicut and his territories compromise a space of three months journey.

Srinatha is known to have lived a life of pleasure and moved on equal terms with the ministers in the king's court, though he died a poor man.
