In 1524, Krishnadevaraya made his son Tirumala Raya the "Yuvaraja" (crown prince). The prince did not survive for long: he was poisoned to death. Suspecting the involvement of Timmarusu, Krishna Deva Raya had his trusted commander and adviser blinded. At the same time, Krishnadevaraya was preparing for an attack on Belgaum, which was in the Adil Shah's possession. Around this time, Krishnadevaraya took seriously ill. He died on 17 October 1529. Before his death, he nominated his brother, Achyuta Deva Raya as his successor. Achyuta Deva Raya was crowned on the fourth day after the death of Krishna Devaraya.
